Experimental aesthetics has shed light on the involvement of pre-motor areas in the perception of abstract art. However, the contribution of texture perception to aesthetic experience is still understudied. We hypothesized that digital screen-based art, despite its immateriality, might suggest potential sensorimotor stimulation. Original born-digital works of art were selected and manipulated by the artist himself. Five behavioral parameters: Beauty, Liking, Touch, Proximity, and Movement, were investigated under four experimental conditions: Resolution (high/low), and Magnitude (Entire image/detail). These were expected to (...) modulate the quantity of material and textural information afforded by the image. While the Detail condition afforded less content-related information, our results show that it augmented the image’s haptic appeal. High Resolution improved the haptic and aesthetic properties of the images. Furthermore, aesthetic ratings positively correlated with sensorimotor ratings. Our results demonstrate a strict relation between the aesthetic and sensorimotor/haptic qualities of the images, empirically establishing a relationship between beholders’ bodily involvement and their aesthetic judgment of visual works of art. In addition, we found that beholders’ oculomotor behavior is selectively modulated by the perceptual manipulations being performed. The eye-tracking results indicate that the observation of the Entire, original images is the only condition in which the latency of the first fixation is shorter when participants gaze to the left side of the images. These results thus demonstrate the existence of a left-side bias during the observation of digital works of art, in particular, while participants are observing their original version. (shrink)

During the pandemic there were many ways of handling the contagious SARS-CoV-2 virus, most of them in haptic terms, or in terms of touch: masks, hand disinfection, social distancing, quarantines, (self)isolations. Touch thus became not only the privileged object of the new bio-politics, striving to preserve life at all costs, but also what was lost during the pandemic. To be sure, a loss of something we never had that even the vaccine, which promised a return to normal, but actually (...) paved the way for a “brave new post-pandemic world,” could not rehabilitate. In short, one of the elements that radically changed with and in the (post-)pandemic world is precisely the elusive object of touch, which we propose to conceptually grasp through the coinage of the concept of its “mateReal hapticity.”.

This article presents a conceptual discussion on the phenomenon of incorporation of tools and other objects in the light of Maine de Biran’s philosophy of the relation between the body and the motor will. Drawing on Maine de Biran’s view of the body as that portion of the material world which directly obeys one’s motor will, as well as on his view (supported by studies in contemporary cognitive science) of active touch as the perceptual modality that is sensitive to (...) objects as fields of forces resisting the perceiver’s movements, we discuss the phenomena of motor incorporation and haptic incorporation, as well as the relation between them. Motor incorporation occurs when something is integrated into the motor system, i.e. when practice enables one to animate an object as directly, effortlessly and fluently as one is able to animate one’s own body. The subject then has the experience of acting there, where the object is located, not at the body–object interface. In order to better understand the phenomenon of motor incorporation, we highlight the phenomenological difference between directly and indirectly moving something. Haptic incorporation occurs when something is integrated into the haptic system, i.e. when an object is used as an instrument for the haptic perception of other objects. Finally, we seek to shed light on the phenomenon of transparency, understanding the transparency acquired by the incorporated object as both a relational property and a matter of degrees. (shrink)

A further step in Pylyshyn's discontinuity thesis is to examine the penetrability of haptic (tactual-kinesthetic) perception. The study of the perception of orientation and the “oblique effect” (lower performance in oblique orientations than in vertical–horizontal orientations) in the visual and haptic modalities allows this question to be discussed. We suggest that part of the visual process generating the visual oblique effect is cognitively impenetrable, whereas all haptic processes generating the haptic oblique effect are cognitively penetrable.

Enactive cognitive science (ECS) and ecological psychology (EP) agree that active movement is important for perception, but they remain ambiguous regarding the precise role of agency. EP has focused on the notion of sensorimotor invariants, according to which bodily movements play an instrumental role in perception. ECS has focused on the notion of sensorimotor contingencies, which goes beyond an instrumental role because skillfully regulated movements are claimed to play a constitutive role. We refer to these two hypotheses as instrumental agency (...) and constitutive agency, respectively. Evidence comes from a variety of fields, including neural, behavioral, and phenomenological research, but so far with confounds that prevent an experimental distinction between these hypotheses. Here we advance the debate by proposing a novel double-participant setup that aims to isolate agency as the key variable that distinguishes bodily movement in active and passive conditions of perception. We pilot this setup with a psychological study of width discrimination using the Enactive Torch, a haptic sensory substitution device. There was no evidence favoring the stronger hypothesis of constitutive agency over instrumental agency. However, we caution that during debriefing several participants reported using cognitive strategies that did not rely on spatial perception. We conclude that this approach is a viable direction for future research, but that greater care is required to establish and confirm the desired modality of first-person experience. (shrink)

This article explores forms of haptic sociality in interspecies interaction. Data examined are taken from a corpus of equine assisted therapy sessions, in Finland and France. During these sessions, therapists invite clients to pay close attention to the horse’s behavioral displays of comfort or discomfort and to react accordingly. In this way, the horse is regarded as a living, sentient creature, whose body has haptic and kinesthetic properties, resulting in socialization practices that cultivate forms of care. The study (...) discusses Merleau-Ponty’s concept of “esthesiologic body”, in light of analytical instances, draws on contemporary re-examinations of phenomenological notions (such as intersubjectivity and intercorporeality) by ethnomethodologists and analysts of social interaction, and proposes to respecify them in the particular context of human–animal interactions. The argument is inspired by a conversation analytic approach, sensitive to the orderly character of social actions. Two formats, displaying diverse ways in which participants interact with the horse as an _esthesiologic_ body, are examined in detail. The analysis shows the fundamental role played by touch and haptic practices in the practical accomplishment of intercorporeality. (shrink)

Haptic object recognition is usually an efficient process although slower and less accurate than its visual counterpart. The early loss of vision imposes a greater reliance on haptic perception for recognition compared to the sighted. Therefore, we may expect that congenitally blind persons could recognize objects through touch more quickly and accurately than late blind or sighted people. However, the literature provided mixed results. Furthermore, most of the studies on haptic object recognition focused on performance, devoting (...) little attention to the exploration procedures that conducted to that performance. In this study, we used iCube, an instrumented cube recording its orientation in space as well as the location of the points of contact on its faces. Three groups of congenitally blind, late blind and age and gender-matched blindfolded sighted participants were asked to explore the cube faces where little pins were positioned in varying number. Participants were required to explore the cube twice, reporting whether the cube was the same or it differed in pins disposition. Results showed that recognition accuracy was not modulated by the level of visual ability. However, congenitally blind touched more cells simultaneously while exploring the faces and changed more the pattern of touched cells from one recording sample to the next than late blind and sighted. Furthermore, the number of simultaneously touched cells negatively correlated with exploration duration. These findings indicate that early blindness shapes haptic exploration of objects that can be held in hands. (shrink)

A general shortcoming of the localist, decompositional, approach to neuroscientific explanation that the target article exemplifies, is that it is incomplete unless supplemented with an account of how the hypothesized subsystems integrate in the normal case. Besides, a number of studies that show that object recognition is proprioception dependent and that cutaneous information affects motor performance make the existence of the proposed subsystems doubtful.

Although acoustic frequency is not a spatial property of physical objects, in common language, pitch, i.e., the psychological correlated of frequency, is often labeled spatially (i.e., “high in pitch” or “low in pitch”). Pitch-height is known to modulate (and interact with) the response of participants when they are asked to judge spatial properties of non-auditory stimuli (e.g., visual) in a variety of behavioral tasks. In the current study we investigated whether the modulatory action of pitch-height extended to the haptic (...) estimation of height of a virtual step. We implemented a HW/SW setup which is able to render virtual 3D objects (stair-steps) haptically through a PHANTOM device, and to provide real-time continuous auditory feedback depending on the user interaction with the object. The haptic exploration was associated with a sinusoidal tone whose pitch varied as a function of the interaction point’s height within (i) a narrower and (ii) a wider pitch range, or (iii) a random pitch variation acting as a control audio condition. Explorations were also performed with no sound (haptic only). Participants were instructed to explore the virtual step freely, and to communicate height estimation by opening their thumb and index finger to mimic the step riser height, or verbally by reporting the height in centimeters of the step riser. We analyzed the role of musical expertise by dividing participants into non musicians and musicians. Results showed no effects of musical pitch on high-realistic haptic feedback. Overall there is no difference between the two groups in the proposed multimodal conditions. Additionally, we observed a different haptic response distribution between musicians and non musicians when estimations of the auditory conditions are matched with estimations in the no sound condition.

The last decade has seen rise in technologies that allow humans to send and receive intimate touch across long distances. Drawing together platform studies, digital intimacy studies, phenomenology of touch, and ethics of technology, we argue that these new haptic communication devices require specific ethical consideration of consent. The paper describes several technologies, including Kiiroo teledildonics, the Kissenger, the Apple Watch, and Hey Bracelet, highlighting how the sense of touch is used in marketing to evoke a feeling (...) of connection within the digital sphere. We then discuss the ambiguity of skin-to-skin touch and how it is further complicated in digital touch by remediation through platforms, companies, developers, manufacturers, cloud storage sites, the collection and use of data, research, satellites, and the internet. Lastly, we raise concerns about how consent of data collection and physical consent between users will be determined, draw on examples in virtual reality and sex-robotics, and ultimately arguing for further interdisciplinary research into this area.

In this paper, we study the interactional organization of an instructed object exploration among sighted and visually impaired people (VIPs) in order to contribute to studies of instructional activities and the observable accomplishment of haptic perception. We do this by showing the situated, interactional, and co-operative organization of achieving object understanding. We focus on the dynamics of haptic perception as being reliant on instructions, while at the same time being an observable production that furnishes further instructions. We (...) show the organization of visual and verbal instructions versus the touching of objects for haptic perception. Based on ethnomethodological conversation analysis of video data, we study a VIP’s haptic actions in interaction with a professional, sighted ICT consultant who provides instructions on what an object is and what it can do. We show how the instructions are sequentially adjusted to make them relevant for a simultaneous, emerging exploration in which the VIP uses their hands and fingers to perceive very specific details of the object. We argue that achieving object understanding is accomplished in and through the fine-tuned coordination of haptic exploration, both as a response to verbal instructions and also as a means of conveying perception-related actions, which the ICT uses to build new actions. The paper thus makes a case for instructed and distributed haptic perception as observable in social interaction and as a resource for building object understanding within phenomenal fields.

In the last decades, the rapid growth of functional brain imaging methodologies allowed cognitive neuroscience to address open questions in philosophy and the social sciences. At the same time, novel insights from cognitive neuroscience research have begun to influence various disciplines, leading to a turn to cognition and emotion in the fields of planning and architectural design. Since 2003, the Academy of Neuroscience for Architecture has been supporting ‘neuro-architecture’ as a way to connect neuroscience and the study of behavioral responses (...) to the built environment. Among the many topics related to multisensory perceptual integration and embodiment, the concept of hapticity was recently introduced, suggesting a pivotal role of touch and haptic imagery in architectural appraisal. Arguments have thus risen in favor of the existence of shared cognitive foundations between hapticity and the supramodal functional architecture of the human brain. Precisely, supramodality refers to the functional feature of defined brain regions to process and represent specific information content in a more abstract way, independently of the sensory modality conveying such information to the brain. Here we highlight some commonalities and differences between the concepts of hapticity and supramodality according to the distinctive perspectives of architecture and cognitive neuroscience. This comparison and connection between these two different approaches may lead to novel observations in regard to people-environment relationships, and even provide empirical foundations for a renewed evidence-based design theory.

Previous research in the social sciences has shown that haptic interaction rituals are critical for maintaining social relationships. However, during the coronavirus pandemic, ‘social distancing’ was encouraged in order to avoid the spread of disease. Drawing on data from self-ethnography as well as publicly available resources, in this study we explore some new, locally negotiated haptic trajectories to accomplish interaction rituals in the time of coronavirus. First, we present self-ethnographic observations of distancing in face-to-face encounters from our everyday (...) lives. Second, utilizing methods of microanalysis of naturally occurring interaction, we investigate video recordings of the embodied negotiation of space and touch among politicians. We analyze three different ways in which politicians negotiate transitional moves in this haptic ritual when one party initiates a handshake: repairing, declining and apologizing. Our analysis shows that politicians adapt their entire bodies in conjunction with talk, gestures and laughter not only to accomplish the greeting but also to remedy the potentially face-threatening situation of not getting the greeting right. This research has implications for better understanding the spontaneous ability of human beings to invent new ways of engaging with each other. Moreover, it adds to our knowledge of how the materiality of human bodies can impact forms of sociality. (shrink)

A Touch of Doubt traces the theme of touch in the evolution of skepticism through Platonism, German idealism, Continental philosophy and psychoanalysis. Haptic Scepticism, the field of ethics emerging from this study, explores the grasp-ability of contradiction. Contradiction is a haptic marvel. We can cup it in our palms, press it against our lips, dip our toes into its coolness, and, if we are not careful, we may even burn ourselves on its surface.

The aim of this essay is to extend and refine the concept of ‘haptic visuality’ which has taken decisive shape in film studies so that it can be used to describe narrative form. In recent theory, the haptic has on the whole been set in opposition to narrative. Should narrative cinema then be understood in and through its neglect or disavowal of haptic visuality? Or might certain feature films in fact incorporate haptic imagery, without thereby (...) ceasing to narrate? These are questions urgently provoked by Lynne Ramsay's brilliant first feature film, Ratcatcher. The answer proposed here takes its bearings from the history of literary and filmic Naturalism, and from the understanding of narrative process Siegfried Kracauer develops in his Theory of Film.

This paper discusses spatial cognition in the domain of minimally invasive surgery. It draws on studies from this domain to shed light on a range of spatial cognitive processes and to consider individual differences in performance. In relation to modeling, the aim is to identify potential opportunities for characterizing the complex interplay between perception, action, and cognition, and to consider how theoretical models of the relevant processes might prove valuable for addressing applied questions about surgical performance and training.

This article focuses on how to provide environmental descriptions of the context with the intent of creating access to information and dialogical participation for deafblind persons. Multimodal interaction is needed to communicate with deafblind persons whose combined sensory loss impedes their access to the environment and ongoing interaction. Empirical data of interpreting for deafblind persons are analyzed to give insight into how this task may be performed. All communicative activities vary due to their context, participants, and aim. In this study, (...) our data are part of a cross-linguistic study of tactile sign language and were gathered during a guided tour for a deafblind group. The guided tour was tailored to a specific group (adult deafblind tactile signers and their interpreters) visiting one of the oldest cathedrals and pilgrim sites in Scandinavia, with interpreters following up the guide’s presentation and providing descriptions based on the given situation. The tour and the interpreters’ work were videotaped, and the ongoing interaction and communication have been studied through video-ethnographic methods and conversational analysis. The data have been investigated for the research question: What elements are involved in descriptions to provide deafblind individuals access to their environments? Theories from multimodality communicative studies are relevant for the ways tactile descriptions are presented and analyzed. Some of this is an investigation at a microlevel of interaction. An overall inspiration for this study is interaction studies with data from authentic formal and informal conversations and ways of analyzing embodied action and situated gestures in studies of human interaction. Also, concepts of “frontstage,” “backstage,” and “main conversation” are brought into our interpreter-mediated data to follow the role of building meaning in complex conversations. Theories on interaction are used in the analyses to illustrate the participating framework between the guide, the interpreter, the deafblind person, and the situated frame of their interaction. The study opens for a broader understanding of the repertoire of multimodal interaction and how such interaction may be handled as inputs in communication processes. This is of relevance for communication with deafblind persons, for professionals meeting blind and deafblind clients, and for knowledge of multimodal interaction in general. (shrink)

In recent years, there has been a significant increase in research on mediated communication via social touch. Previous studies indicated that mediated social touch can induce similar positive outcomes to interpersonal touch. However, studies investigating the user experience of MST technology predominantly involve brief experiments that are performed in well-controlled laboratory conditions. Hence, it is still unknown how MST affects the relationship and communication between physically separated partners in a romantic relationship, in a naturalistic setting and over a (...) longer period of time. In a longitudinal explorative field study, the effects of MST on social connectedness and longing for touch among geographically separated romantic couples were investigated in a naturalistic setting. For 2 weeks, 17 couples used haptic bracelets, that were connected via the internet, to exchange mediated squeeze-like touch signals. Before and after this period, they reported their feelings of social connectedness and longing for touch through questionnaires. The results show that the use of haptic bracelets enhanced social connectedness among geographically separated couples but did not affect their longing for touch. Interviews conducted at the end of the study were analyzed following the thematic analysis method to generate prominent themes and patterns in using MST technology among participant couples. Two main themes were generated that captured the way the bracelets fostered a positive one-to-one connection between partners and the way in which participants worked around their frustrations with the bracelets. Detailed findings and limitations of this longitudinal field study are further discussed, and suggestions are made for future research. (shrink)

Haptic-based vibrotactile biofeedback (BF) is a promising technique to improve rehabilitation of balance in stroke patients. However, the extent to which BF training changes temporal structure of the center of pressure (CoP) trajectories remains unknown. This study aimed to investigate the effect of vibrotactile BF training on the temporal structure of CoP during quiet stance in chronic stroke patients using detrended fluctuation analysis (DFA). Nine chronic stroke patients (age; 81.56±44 months post-stroke) received a balance training regimen using a vibrotactile (...) BF system twice a week over four weeks. A Wii Balance board was used to record five 30 s trials of quiet stance pre- and post-training at 50 Hz. DFA revealed presence of two linear scaling regions in CoP indicating presence of fast- and slow-scale fluctuations. Averaged across all trials, fast-scale fluctuations showed persistent dynamics ( = 1.05 ±.08 for ML and  = 0.99 ±.17 for AP) and slow-scale fluctuations were anti-persistent ( = 0.35 ±.05 for ML and  = 0.32 ±.05 for AP). The slow-scale dynamics of ML CoP in stroke patients decreased from pre-training to post-BF training ( = 0.40 ±.13 vs. 0.31 ±.09). These results suggest that the vibrotactile BF training affects postural control strategy used by chronic stroke patients in the ML direction. Results of the DFA are further discussed in the context of balance training using vibrotactile BF and interpreted from the perspective of intermittent control of upright stance. (shrink)

The article deals with four forms of power grabs through the conceptual connection between touch and power, focusing on four structural breakthroughs that show the changing process that this relation underwent, from the secularisation of the sacral via profane materialism until contemporary vulgar-materialism: Christian _Noli me tangere; _monarchic _King’s Evil; _materialistic _Warenfetischismus_; and profane _Grab-’em-by-the-pussy. _.

This study aimed at evaluating the role of proprioception in the process of matching the final position of one's limbs with an intentional movement. Two experiments were realised with the same paradigm of conscious recognition of one's own limb position from a distorted position. In the first experiment, 22 healthy subjects performed the task in an active and in a passive condition. In the latter condition, proprioception was the only available information since the central signals related to the motor command (...) were likely to be absent. The second experiment was realised with a deafferented patient who suffers from a complete haptic deafferentation, including loss of proprioception. The results first argue in favour of a dominant role of proprioception in action recognition, but they also stress the possible role of central signals. The process of matching the final position of one's limbs with an intended movement and thus of action recognition would be achieved through a comparison process between the predicted sensory consequences of the action, which are stored in its internal model, and the actual sensory consequences of that action.

Previous studies have shown that object properties are processed faster when they follow properties from the same perceptual modality than properties from different modalities. These findings suggest that language activates sensorimotor processes, which, according to those studies, can only be explained by a modal account of cognition. The current paper shows how a statistical linguistic approach of word co-occurrences can also reliably predict the category of perceptual modality a word belongs to (auditory, olfactory–gustatory, visual–haptic), even though the (...) statistical linguistic approach is less precise than the modal approach (auditory, gustatory, haptic, olfactory, visual). Moreover, the statistical linguistic approach is compared with the modal embodied approach in an experiment in which participants verify properties that share or shift modalities. Response times suggest that fast responses can best be explained by the linguistic account, whereas slower responses can best be explained by the embodied account. These results provide further evidence for the theory that conceptual processing is both linguistic and embodied, whereby less precise linguistic processes precede precise simulation processes.

The development of immersive media-communication environments, and their theorization in terms of the `haptic', calls for a reconsideration of the relationship between sensuality and the ethics of contact. For the most part, the cultural theorization of the virtual which remains preoccupied with the visual has tended to limit its scope to the paradoxes, politics and ethics of representation. Much of media and cultural studies work, for instance, has adopted, directly or indirectly, the traditional visual and ocularcentric paradigm in (...) its analyses of cultural forms and technologies as these have become integrated into contemporary life. Whilst it has been argued, for instance by Mark Hansen in his recent books, that this paradigm is inadequate to digital media and the developments of human-machine interactions the digital introduces, few comentators have addressed how new developments in immersive sensory media environments bear on the ethics of communication. By way of a reflection on the themes of the tactility of contact and the ethics of touch in the work of Emmanuel Levinas, this article critically evaluates the ethical significance of the `sensory extension' haptic media represent. It identifies and argues against the neo-positivist tendency of Hansen's reliance on the empiricism of the neurosciences whilst locating the resources for an ethics of touch in Levinas' concept of time as `diachrony'.

Proprioception has a crucial role in promoting or hindering motor learning. In particular, an intact position sense strongly correlates with the chances of recovery after stroke. A great majority of neurological patients present both motor dysfunctions and impairments in kinesthesia, but traditional robot and virtual reality training techniques focus either in recovering motor functions or in assessing proprioceptive deficits. An open challenge is to implement effective and reliable tests and training protocols for proprioception that go beyond the mere position sense (...) evaluation and exploit the intrinsic bidirectionality of the kinesthetic sense, which refers to both sense of position and sense of movement. Modulated haptic interaction has a leading role in promoting sensorimotor integration and it is a natural way to enhance volitional effort. Therefore, we designed a preliminary clinical study to test a new proprioception-based motor training technique for augmenting kinesthetic awareness via haptic feedback. The feedback was provided by a robotic manipulandum and the test involved 7 chronic hemiparetic subjects over three weeks. The protocol included evaluation sessions, that consisted of a psychometric estimate of the subject’s kinesthetic sensation, and training sessions, in which the subject executed planar reaching movements in the absence of vision and under a minimally assistive haptic guidance made by sequences of graded force pulses. The bidirectional haptic interaction between the subject and the robot was optimally adapted to each participant in order to achieve a uniform task difficulty over the workspace. All the subjects consistently improved in the perceptual scores as a consequence of training. Moreover, they could minimize the level of haptic guidance in time. Results suggest that the proposed method is effective in enhancing kinesthetic acuity, but the level of impairment may affect the ability of subjects to retain their improvement in time. (shrink)

The studies cited by Dijkerman & de Haan (D&dH) stress the distinction between perception and action within the somatosensory system but provide little information about memory functions. Recent findings by our group and by others show that the dorsal stream is also activated during short-term memory maintenance and long-term memory retrieval of haptic information. These data complement and extend the proposed model.

Sensory feedback, which can be presented in different modalities - single and combined, aids task performance in human-robot interaction (HRI). However, combining feedback modalities does not always lead to optimal performance. Indeed, it is not known how feedback modalities affect operator performance under stress. Furthermore, there is limited information on how feedback affects neural processes differently for males and females and under stress. This is a critical gap in the literature, particularly in the domain of surgical robotics, where surgeons are (...) under challenging socio-technical environments that burden them physiologically. In the present study, we posited operator performance as the summation of task performance and neurophysiological cost of maintaining that performance. In a within-subject design, we used functional near-infrared spectroscopy (fNIRS) to assess cerebral activations of 12 participants who underwent a 3D manipulation task within a virtual environment with concurrent feedback (visual and visual + haptic) in the presence and absence of a cognitive stressor. Cognitive stress was induced with the serial-7 subtraction test. We found that while task performance was higher with visual than visual + haptic feedback, it degraded under stress. The two feedback modalities were found to be associated with varying neural activities and neural efficiencies, and these were stress- and gender-dependent. Our findings engender further investigation into effectiveness of feedback modalities on males and females under stressful conditions in HRI. (shrink)

Haptic sensation of a material can be modulated by its visual appearance. A technique that utilizes this visual-haptic interaction is called as pseudo-haptic feedback. Conventional studies have investigated pseudo-haptic feedback in situations, wherein a user manipulated a virtual object using a computer mouse, a force-feedback device, etc. The present study investigated whether and how it was possible to offer pseudo-haptic feedback to a user who manipulated a virtual object using keystrokes. Participants moved a cursor (...) toward a destination by pressing a key. While the cursor was moving, the cursor was temporarily slowed down on a square area of the screen. The participants’ task was to report, on a five-point scale, how much resistance they felt to the cursor’s movement. In addition to the basic speed of the cursor, the ratio of the basic speed to the speed within the square area was varied. In Experiment 1, we found that these two factors interacted significantly with each other, but further analysis showed that the cursor speed within the square area was the most important determinant of perceived resistance. In Experiment 2, consistent with the results of the previous experiment, it was found that the cursor movement outside of the square area was not required to generate the sense of resistance. Counterintuitively, in Experiment 3, the sense of resistance was apparent even without user’s keystrokes. We discuss how the sense of resistance for a cursor moved by keystrokes can be triggered visually, but interpreted by the brain as a haptic impression. (shrink)

Modernist literature of the early to mid-twentieth century on both sides of the Atlantic is replete with examples of a particular kind of relationship with objects, namely, the touching, collecting, and grasping of small, often highly personal, and ostensibly quotidian objects. From John’s glass collection in Woolf’s “Solid Objects,” Peter Walsh’s stroking of his pocket-knife in Mrs. Dalloway, Miriam’s frenzied absorption with flowers in Lawrence’s Sons and Lovers, to Laura’s fiddling of her glass menagerie in Tennessee Williams’s eponymous play, fidgeting (...) in modernist literature and drama reveals a particular tendency of not just characters’ possession of things but also their possession by things. This phenomenon, I argue, allows characters to practice care as they withdraw from oppressive narratives of normalcy and (economic and biological) productivity, challenging their exclusionary and othering configurations. My paper looks at fidgeting in The Glass Menagerie as a part of this larger ideological and haptic orientation in modernist literature. The care invested by Laura in her intimate relationship with these “playthings” allows her to intercept not only male narrativizing forces and articulation of herself but also the rhetoric of productivity that circulates both within the play and in the larger economic backdrop of post-depression America. My paper attempts to foreground these objects of care in our readings of the play and modernist texts in general and, in so doing, highlight their importance as lenses of analysis that render visible alternate forms of agency and resistance. Lastly, it attempts to reframe fidgeting as an act of embodied refusal, evoking the radical potential of refusal within feminist and disability studies. (shrink)

Abstract:The haptic sense is an essential component of aesthetic evaluation that is often overlooked in today’s mobile internet age. Unlike hearing and vision, the sense of touch is less widely transmitted. Unfortunately, most aesthetic theories and explanations have focused solely on the visual and auditory senses, with minimal attention given to tactile evaluation. To address this gap in knowledge, we have collected studies on tactile aesthetics within the framework of experimental aesthetics from 2000 to 2022. After statistical generalization, (...) our findings suggest the following: The criteria for evaluating tactile aesthetics were mostly dichotomous, that is, positive (like/appreciation/pleasure) and negative (dislike/disgust/unpleasant). Tactile aesthetics predominantly involved the toucher dimension (synesthesia/need for touch/touch pattern) and the touch sample dimension (shape/type/texture), with the commonly overlooked factors of “need for touch” and “touch pattern.” Some studies did not restrict the shape and material of the touch samples. Based on our findings, we have systematically summarized and concluded what tactile factors influence aesthetic evaluation and have analyzed future research trends. (shrink)

In their exhaustive study of the cognitive operation of analogy, Hofstadter and Sander arrive at a paradox: the creative and inexhaustible production of analogies in our thought must derive from a “reminding” operation based upon the availability of the detailed totality of our experience. Yet the authors see no way that our experience can be stored in the brain in such detail nor do they see how such detail could be accessed or retrieved such that the innumerable analogical remindings we (...) experience can occur. Analogy creation, then, should not be possible. The intent here is to sharpen and deepen our understanding of the paradox, emphasizing its criticality. It will be shown that the retrieval problem has its origins in the failure of memory theory to recognize the actual dynamic structure of events. This structure is comprised of invariance laws as per J. J. Gibson, and this event “invariance structure” is exactly what supports Hofstadter and Sander’s missing mechanism for analogical reminding. Yet these structures of invariants, existing only over optical flows, auditory flows, haptic flows, etc., are equally difficult to imagine being stored in a static memory, and thus only exacerbate the problem of the storage of experience in the brain. A possible route to the solution of this dilemma, based in the radical model of Bergson, is also sketched. (shrink)

This study reviews the current information concerning the measurement of the situation awareness (SA) of the teleoperated drivers of remotely controlled cars. The teleoperated drivers who drive these cars are in a remote location, and they control the cars through a communication interface. The objective methods with probes are beneficial in measuring SA on a closed circuit without real traffic. Questions specifically should address the information provided on the road by haptic sensations, such as the slope of the road (...) and the vehicle's speed. Methods for measuring SA that involve probes and interruptions obviously are not suitable for use on public roads. A stable environment for the display and control of the communication interface is suitable for an eye tracker in measuring SA. These features also facilitate the use of subjective observer-rating methods. Both of these methods are suitable for driving on real roads because they are not intrusive. SA research in a real-road environment also should demonstrate how the SA of other drivers is affected by seeing a car without a driver. Given the remote character of driving, cultural differences in cognition may have a significant influence on the SA of the teleoperated driver. (shrink)

This book is a study in film and philosophy that explores the intersection of global post-fascist cinema, ethics and justice, and screen bodies. It addresses the question "What is the good of film experience?" by staging an encounter between Levinasian-Derridean concerns over ethics and justice and cinematic engagements with issues of embodied and haptic response. In the end, this book argues such international filmmaking provokes us to respond through a redeployment of our questions of ethics and justice as well (...) as our questions of film making and experiencing.

Through a close study of T. Yunkaporta's 2019’s Sand Talk, this article explores fractal thinking and the pattern of creation in Indigenous cosmology; the role of custodianship in respectful interaction between living systems; alternative Indigenous understandings of nonlinearity, time, and transience; the process-panpsychism and animism present in Indigenous perceptions of cosmos as living Country, illustrated in the Dreaming and Turnaround creation event; the role of embodied cognition and haptic and situated knowledge in Indigenous science; Indigenous holistic reasoning and the (...) mind-body connection; the process-relational metaphysic embedded in ritual and yarning practice; the knowledge encoded in place-based totemic mythology, lore, and ritual; and Indigenous understandings of complex systems as adaptive, self-organizing, and patterned. This article does not offer a process reading of Indigenous thought but rather demonstrates the significant contribution to process metaphysics that may be provided by an Aboriginal Australian perspective. Yunkaporta's text carves out a language of resistance to the McDonaldization of Indigenous research. While historic scholarly engagement with Aboriginal culture has overemphasized content, Yunkaporta demonstrates how this has occurred to the exclusion of the processes of Indigenous knowledge transmission and creation. Yet a process view requires engagement with the how, not only with the what. Such knowledge transmission is discerned in daily lived relationships among land, spirit, and people—binding epistemology to participation in a specific landscape embedded within a living culture. Place-making for Indigenous knowledges requires exploring how Indigenous ways of valuing, knowing, and being, shaped by cultural activities on Country, offer new understandings for Western metaphysics.

In the digital era, digital games, particularly those in virtual spaces, have become integral to daily life, offering users not only a blend of real and virtual world interactions but also an enhanced sense of happiness and fulfilment. However, traditional digital gaming modes often fall short in meeting the increasing demands for higher quality and more immersive experiences. This paper proposes a new model for the development of artificial intelligence-driven digital games based on virtual space, addressing the ethical and spiritual (...) implications of such advancements. The research builds on data from a 2018 user expectation survey, which indicated significant demand for enhanced virtual reality (VR) games, improved voice communication, and tactile interaction within these environments. We developed a multidimensional model incorporating vision, touch, and auditory feedback, utilizing a Kinect-based haptic interaction redirection algorithm to enhance physical-virtual interaction. This algorithm significantly reduces angular deviation by 10% in virtual navigation, enhancing the boundary definition in virtual spaces and thereby improving the immersive experience. Further enhancements include an Encoder-Decoder (ED) framework for voice communication that employs a neural network with multiple feedback loops to adjust weight values, improving speech recognition accuracy by 15%. This system provides a more responsive and realistic communication environment within digital games. Lastly, the application of computer vision technology and deep learning techniques, including a backpropagation (BP) neural network, improves the system's image recognition capabilities, extending its precision and capacity for rendering high-definition, precise game graphics. This study not only advances the technical aspects of AI in gaming but also prompts a deeper philosophical discussion on the ethical and spiritual impacts of these immersive virtual environments. As AI continues to blur the lines between reality and virtuality, this research invites further inquiry into how such technologies influence human perception, behavior, and morality within digital spaces.

The past is not dead. In fact, it’s not even past.(William Faulkner)This article investigates ‘transcultural tendencies’ and ‘transmedial transaction’ between the Sasanian, the last dynasty to rule the Persian plateau, and the Muslims who conquered this land. These transactions and exchanges took place during the seventh century in the Ērānshahr distributing lots of different features, cultures, languages, religions, sciences and artistic achievements by the Persian people and sharing them with Muslim territories from the East to the West. The article also (...) investigates the Shu’ubiyya parties, which were a non-Arab Muslim response to the privileged status of Arabs within them that would later become Sufism. The protest approach travelled in its haptic spaces from ancient Iranian times to the present day, carrying the same habits and cultures, and among protesters characterizes contemporary artists in particular. In my study, I have classified them and decoded their artistic practices. Through this article, I investigate them by looking to contemporary art practices, which contain protest language, and identifying common ground with Sufism ideology. I bring them into the light, through a non-Islamic perspective that carries a lot of truth and spirituality, which I found both Iranian people and the global culture at large need to be reacquainted with. People need to understand how and why this perspective matters in the modern world, as well as the ways in which it is relevant. How does or would it affect the world of Internet, new media, the mix of old and new media in today’s and tomorrow’s cultures? The Sasanian Empire fell to Arab Muslims, and consequently the ‘transcultural tendencies’ took place around the beginning of the seventh century (AD 628) with the death of the last great Sassanid kings of Shahanshah Khusroparviz. I wish to take up the challenge of understanding more of Iranian history at the moment of transition that occurred at the end of the Sassanid epoch. This era (historical–cultural period) can be said to have characterized the beginning of the Islamic period. The question is how did this newborn culture, an outgrowth of this ‘transactive’ movement, spread through contemporary Iranian lifestyle? (shrink)

Modality specificity in priming is taken as evidence for independent perceptual systems. However, Easton, Greene, and Srinivas (1997) showed that visual and haptic cross-modal priming is comparable in magnitude to within-modal priming. Where appropriate, perceptual systems might share like information. To test this, we assessed priming and recognition for visual and auditory events, within- and across- modalities. On the visual test, auditory study resulted in no priming. On the auditory priming test, visual study resulted in priming that was only (...) marginally less than within-modal priming. The priming results show that visual study facilitates identification on both visual and auditory tests, but auditory study only facilitates performance on the auditory test. For both recognition tests, within-modal recognition exceeded cross-modal recognition. The results have two novel implications for the understanding of perceptual priming: First, we introduce visual and auditory priming for spatio-temporal events as a new priming paradigm chosen for its ecological validity and potential for information exchange. Second, we propose that the asymmetry of the cross-modal priming observed here may reflect the capacity of these perceptual modalities to provide cross-modal constraints on ambiguity. We argue that visual perception might inform and constrain auditory processing, while auditory perception corresponds to too many potential visual events to usefully inform and constrain visual perception.

This article introduces the problem of inexistence to studies in genre and gender, providing a hermeneutic point of reference for literary history and trans theory. It seeks to negotiate the affinities and disaffinities between queer and trans by foregrounding the latter’s struggle for existence against the former’s mobilization of a rhetoric of negative relationality, while at the same time preserving the bonds of intimacy across and beyond the coalition of LGBTQIA+. Such queer intimacy is read in relation to a (...) haptic technology of queer close reading, enabling differentially sexed bodies to imaginatively inhabit each other. I begin by considering how Djuna Barnes’s close, haptic readings of Henry James and Marcel Proust enact a reversal of sex, but I consider how the affective evidence of these trans moments do not amount to trans existence but raise the ethical necessity of holding open the difference between the ephemeral trans experiences within cis existence and the real struggle for trans existence of trans subjects today. Such a divide, however, is simultaneously held against the moments of intimacy that are capable of being produced across cis and trans subjects through such close reading and cross-inhabitation of bodies. To read trans literary history before trans, I thus propose the notion of trans inexistence through an interpretation of Jacques Maritain’s figure of the “angel” and Hegel’s “beautiful soul.” By situating Barnes’s and Jean Genet’s own characterizations of their transfeminine characters in terms of the angel in a post-Romantic, Catholic context, I interpret the trans angel as a figure of inexistence, tied to a minimal transcendence from the terms of history and materiality, including the sexed body. Finally, I consider how Genet’s phenomenology of proprioception draws together the problems of queer intimacy, haptic reading, and trans inexistence. In analyzing how Genet and his characters cross-inhabit each other’s bodies via proprioceptive mimicry, I unfold both the vast potential and the limits of the intimacies constructed across cis male and transfeminine lives and the accompanying role played by the literary mode of romance.

Many upper limb amputees experience an incessant, post-amputation “phantom limb pain” and report that their missing limbs feel paralyzed in an uncomfortable posture. One hypothesis is that efferent commands no longer generate expected afferent signals, such as proprioceptive feedback from changes in limb configuration, and that the mismatch of motor commands and visual feedback is interpreted as pain. Non-invasive therapeutic techniques for treating phantom limb pain, such as mirror visual feedback (MVF), rely on visualizations of postural changes. Advances in neural (...) interfaces for artificial sensory feedback now make it possible to combine MVF with a high-tech “rubber hand” illusion, in which subjects develop a sense of embodiment with a fake hand when subjected to congruent visual and somatosensory feedback. We discuss clinical benefits that could arise from the confluence of known concepts such as MVF and the rubber hand illusion, and new technologies such as neural interfaces for sensory feedback and highly sensorized robot hand testbeds, such as the “BairClaw” presented here. Our multi-articulating, anthropomorphic robot testbed can be used to study proprioceptive and tactile sensory stimuli during physical finger-object interactions. Conceived for artificial grasp, manipulation, and haptic exploration, the BairClaw could also be used for future studies on the neurorehabilitation of somatosensory disorders due to upper limb impairment or loss. A remote actuation system enables the modular control of tendon-driven hands. The artificial proprioception system enables direct measurement of joint angles and tendon tensions while temperature, vibration, and skin deformation are provided by a multimodal tactile sensor. The provision of multimodal sensory feedback that is spatiotemporally consistent with commanded actions could lead to benefits such as reduced phantom limb pain, and increased prosthesis use due to improved functionality and reduced cognitive burden.

Clinical bioethics plays a significant role in hospital settings through bioethics consultations, which focus on providing ongoing assistance in complex situations within the doctor-patient dynamic. These consultations entail regular interaction between physicians and clinical bioethicists. This situation prompts an exploration into how bioethics consultations affect physicians. The current research aims to understand the influence of bioethics consultations on physicians’ bioethical knowledge by analyzing the lexical content in their patients’ medical records. Medical records are a synthesis carried out by physicians, often (...) reflecting collaborative efforts, and capturing verbal statements indicative of thought processes suggestive of learning. The study is a sequential mixed-methods design with a retrospective descriptive approach, comparing medical records from the early years of the Department of Humanism and Bioethics’ operation (2013–2015) to the more recent ones (2019). Technical bioethical terminology such as “therapeutic effort limitation,” “futility,” “beneficence,” and “respect for autonomy” is more prevalent in recent medical records. This trend may stem from the positive impact of bioethics consultations conducted by the Department, with haptic communication serving as a particularly effective form of interaction with others during experiences of moral distress. This appears to be characteristic of cultures like those in Latin America. (shrink)

The first section of this issue brings together four essays on “surfaces” – a subject matter which might seem conspicuous or, indeed, palpable enough. Just think of the sheets of paper, window panes, and haptic interfaces surrounding you: the world, evidently, is diffused with surfaces, membranes, and boundaries of all sorts. Some of these things have been salient, for obvious reasons in fields such as media studies, or implicit in notions such as “boundary object”: the retina, photographic plates, (...) basilar membranes, the skin, or various forms of “displays” immediately come to mind. Not even mentioning their immense metaphoricity, surfaces are the entities that make things visible, inscribable, or knowable. But not all of them have been so salient. In fact, most surface-phenomena arguably – and, typically, for similarly obvious reasons – haven't received much scholarly notice at all: plastic wraps, lacquers, lubricants, coatings, silicon wavers, cell membranes, glass, plant leaves, the ozone layer.

This article theorizes the dermalogical turn – heralded by the publication of this special issue – from a sensory studies perspective. Sensory studies involves a cultural approach to the study of the senses and a sensory approach to the study of culture. The skin is both an object and means of perception. Understandings of the skin and of touch vary across cultures: the skin may be seen as social rather than individual, as porous instead of an envelope, and (...) as knowledgeable or sentient in its own right rather than subservient to the eye or brain (i.e. cognition). These contrasting understandings have important implications for practice. Haptic Field, a performative sensory environment designed by Chris Salter, which enables the visitor to try on a second skin, is discussed as a means of shaking up conventional Western understandings of the skin and of touch, and facilitating the communication of skin knowledge across cultures.

According to Gibson's ecological theory of perception-action, the proper objects of perception are affordances. Affordances are directly perceivable, environmental opportunities for behavior. The current study assessed affordance judgments, and the confidence ratings corresponding to those judgments, of aperture pass-through-ability based on three modes of perceiving. The modes were vision and two blindfolded conditions involving haptic perception via technological aids: A cane and the Enactive Torch (ET). The first hypothesis, that vision would provide judgments of the critical boundary most similar (...) to the actual boundary, was not supported. The second hypothesis, that participants would perform better on pass-through-ability judgments using the ET than when using the cane, was supported. The third hypothesis, that across all three modalities participants’ ratings of confidence in the accuracy of their yes/no judgments would be lowest near the perceptual category boundary, was supported. Results suggest that in terms of making affordance judgments of aperture pass-through-ability, participants were more accurate with the haptic modalities than with vision. Results also suggest that participants were least confident with their more accurate modality, and most confident with their least accurate modality. (shrink)
