Resumen
Visual-tactile fused sensing for object clustering has achieved significant progresses recently, since the involvement of tactile modality can effectively improve clustering performance. However, the missing data (i.e., partial data) issues always happen due to occlusion and noises during the data collecting process. This issue is not well solved by most existing partial multi-view clustering methods for the heterogeneous modality challenge. Naively employing these methods would inevitably induce a negative effect and further hurt the performance. To solve the mentioned challenges, we propose a Generative Partial Visual-Tactile Fused (i.e., GPVTF) framework for object clustering. More specifically, we first do partial visual and tactile features extraction from the partial visual and tactile data, respectively, and encode the extracted features in modality-specific feature subspaces. A conditional cross-modal clustering generative adversarial network is then developed to synthesize one modality conditioning on the other modality, which can compensate missing samples and align the visual and tactile modalities naturally by adversarial learning. To the end, two pseudo-label based KL-divergence losses are employed to update the corresponding modality-specific encoders. Extensive comparative experiments on three public visual-tactile datasets prove the effectiveness of our method.

Resumen
Working memory (WM) is limited in capacity, but it is controversial whether these capacity limitations are domain-general or are generated independently within separate modality-specific memory systems. These alternative accounts were tested in bimodal visual/tactile WM tasks. In Experiment 1, participants memorized the locations of simultaneously presented task-relevant visual and tactile stimuli. Visual and tactile WM load was manipulated independently (one, two, or three items per modality), and one modality was unpredictably tested after each trial. To track the activation of visual and tactile WM representations during the retention interval, the visual contralateral delay activity (CDA) and tactile CDA (tCDA) were measured over visual and somatosensory cortex, respectively. CDA and tCDA amplitudes were selectively affected by WM load in the corresponding (tactile or visual) modality. The CDA parametrically increased when visual load increased from one to two and to three items. The tCDA was enhanced when tactile load increased from one to two items and showed no further enhancement for three tactile items. Critically, these load effects were strictly modality-specific, as substantiated by Bayesian statistics. Increasing tactile load did not affect the visual CDA, and increasing visual load did not modulate the tCDA. Task performance at memory test was also unaffected by WM load in the other (untested) modality. This was confirmed in a second behavioral experiment where tactile and visual loads were either two or four items, unimodal baseline conditions were included, and participants performed a color change detection task in the visual modality. These results show that WM capacity is not limited by a domain-general mechanism that operates across sensory modalities. They suggest instead that WM storage is mediated by distributed modality-specific control mechanisms that are activated independently and in parallel during multisensory WM.

Resumen
Abstract The question whether the attentional control of working memory (WM) is shared across sensory modalities remains controversial. Here, we investigated whether attention shifts in visual and tactile WM are regulated independently. Participants memorized visual and tactile targets in a first memory sample set (S1) before encoding targets in a second sample set (S2). Importantly, visual or tactile S2 targets could appear on the same side as the corresponding S1 targets, or on opposite sides, thus, requiring shifts of spatial attention in visual or tactile WM. The activation of WM representations in modality-specific visual and somatosensory areas was tracked by recording visual and tactile contralateral delay activity (CDA/tCDA). CDA/tCDA components emerged contralateral to the side of visual or tactile S1 targets, and reversed polarity when S2 targets in the same modality appeared on the opposite side. Critically, the visual CDA was unaffected by the presence versus absence of concurrent attention shifts in tactile WM, and the tactile CDA remained insensitive to visual attention shifts. Visual and tactile WM performance was also not modulated by attention shifts in the other modality. These results show that the dynamic control of visual and tactile WM activation processes operates in an independent modality-specific fashion.

Resumen
Sites of lesions responsible for visual, tactile, and/or motor extinction have not been clearly identified. We sought to determine the frequency of extinction in various modalities immediately after acute ischemic stroke, the rate of co-occurrence of extinction across modalities, and areas of infarct and/or hypoperfusion associated with each modality of extinction. A total of 148 patients with right supratentorial stroke were studied. In Study 1, 88 patients without hemiplegia, hemianesthesia, or visual field cuts were tested within 24 hours of onset for visual, tactile, and motor extinction, and underwent magnetic resonance diffusion and perfusion imaging. Associations between modality of extinction and areas of neural dysfunction (hypoperfusion/infarct) were identified. Of the 88 patients, 19 had only tactile extinction, 8 had only visual extinction, 12 had only motor extinction, 14 had extinction in two or more modalities, and 35 had no extinction. Tactile extinction was associated with neural dysfunction in the inferior parietal lobule; visual extinction was associated with dysfunction in the visual association cortex; and motor extinction was associated with neural dysfunction in the superior temporal gyrus. In Study 2, data from 60 patients who were excluded from Study 1 because of motor deficits were analyzed in the same way to determine whether frontal lesions contributed to visual or tactile extinction. Results again demonstrated that tactile extinction is associated with inferior parietal dysfunction, and visual extinction is associated with dysfunction of the visual association cortex. Potential accounts of the results, based on the “hemisphere rivalry” model of extinction and the limited attentional capacity model, are considered.

Resumen
Abstract. Modality compatibility refers to the similarity of stimulus modality and modality of response-related sensory consequences. Previous dual-task studies found increased switch costs for modality incompatible tasks (auditory-manual/visual-vocal) compared to modality compatible tasks (auditory-vocal/visual-manual). The present task-switching study further examined modality compatibility and investigated vibrotactile stimulation as a novel alternative to visual stimulation. Interestingly, a stronger modality compatibility effect on switch costs was revealed for the group with tactile-auditory stimulation compared to the visual-auditory stimulation group. We suggest that the modality compatibility effect is based on crosstalk of central processing codes due to ideomotor “backward” linkages between the anticipated response effects and the stimuli indicating this response. This crosstalk is increased in the tactile-auditory stimulus group compared to the visual-auditory stimulus group due to a higher degree of ideomotor-compatibility in the tactile-manual tasks. Since crosstalk arises between tasks, performance is only affected in task switching and not in single tasks.

Resumen
AbstractApparent motion can occur within a particular modality or between modalities, in which a visual or tactile stimulus at one location is perceived as moving towards the location of the subsequent tactile or visual stimulus. Intramodal apparent motion has been shown to be affected or 'captured' by information from another, task-irrelevant modality, as in spatial or temporal ventriloquism. Here we investigate whether and how intermodal apparent motion is affected by motion direction cues or temporal interval information from a third modality. We demonstrated that both moving and asynchronous static sounds can capture intermodal (visual–tactile and tactile–visual) apparent motion; moreover, while the auditory direction cues have less impact upon the perception of intramodal visual apparent motion than upon the perception of intramodal tactile or intermodal visual/tactile apparent motion, the auditory temporal information has equivalent impacts upon both intramodal and intermodal apparent motion. These findings suggest intermodal apparent motion is susceptible to the influence of dynamic or static auditory information in similar ways as intramodal visual or tactile apparent motion.

Resumen
Aujourd'hui, les robots sont de plus en plus présents dans la vie quotidienne. L’étude et le développement de stratégies d'interaction sociale et émotionnelle constitue un point clé de leur insertion dans notre espace social. Ces derniers années, beaucoup de recherches se sont intéressées à la communication homme-robot en exploitant les expressions faciales, posturales ou encore vocales, mais très peu de recherches se sont intéressées à l’interaction physique via le toucher. Cependant, des recherches récentes dans le domaine de la psychologie et des interfaces homme-machine (IHM) ont montré le rôle de la modalité haptique et plus particulièrement tactile dans la perception des émotions et de leurs différentes dimensions (par exemple valence, activation, dominance). L’objectif de ce projet est d’exploiter cette modalité sensorielle dans l'interaction affective homme-robot. Sur la base du robot humanoïde MEKA, un ensemble de capteurs tactiles et physiologiques seront étudiés et développés afin de sensibiliser certaines régions de son corps (ex. bras, épaule, main) et détecter l’état émotionnel de l’utilisateur. Par la suite, une série d’études seront menées afin d'analyser le comportement des utilisateurs dans des situations d’interaction affective avec le robot. Les résultats de ces études nous permettront d’identifier des comportements affectifs haptiques types qui seront utilisés pour modéliser le comportement du robot dans des contextes d’interactions sociales
Today, robots are more and more present in everyday life. The study and the development of strategies of social and emotional interaction constitutes a key point of their insertion in our social space. The latter years, many researches were carried out in the man-robot communication by exploiting the facial expressions, posturals or still vocal, but very few focused on the physical interaction via the touch. However, recent researches in the field of the psychology and the human-machine interfaces (HMI) showed the role of the haptic modality and more particularly tactile in the perception of the feelings and their various dimensions (for example valence, activation, dominance). The objective of this project is to exploit this sensory modality in the emotional man-robot interaction. On the basis of the robot humanoid MEKA, a set of tactile and physiological sensors will be studied and developed to make sensitive certain regions of its body (eg arm, shoulder, hand) and to detect the emotional state of the user. Afterward, a series of studies will be led to analyze the behavior of the users in situations of emotional interaction with the robot. The results of these studies will allow us to identify typical haptic emotional behavior which will be used to model the behavior of the robot in contexts of social interactions

Resumen
When people multi-task with inputs that demand attention, processing, andencoding, sensory interference is possible at almost any level. Multiple Resource Theory (MRT) suggests that such interference may be avoided by drawing from separate pools of resources available when using different sensory channels, memory processes, and even different response modes. Thus, there should be advantages in dividing tasks among different sensory channels to tap independent pools of attentional resources. For example, people are better with two tasks using the eye and ear, than when using two auditory or two visual inputs. The majority of the research on MRT involves visual to auditory comparisons, i.e., the prime distance senses. The unstated implication is that the theory can be easily applied to other sensory systems, such as touch, but this is untested. This overlooks the fact that each sensory system has different characteristics that can influence how information processing is allocated in a multiple-task environment. For example, vision requires a directed gaze that is not required for sound or touch. Testing MRT with touch, not only eliminates competing theories, but helps establish its robustness across the senses. Three experiments compared the senses of touch and hearing to determine if the characteristics of those sensory modalities alter the allocation of processing resources. Specifically, it was hypothesized that differences in sensory characteristics would affect performance on a simple targeting task. All three experiments used auditory shadowing as the dual task load. In the first and third experiments a target was placed to the left or right of the participant and the targeting cue (either tactile, auditory, or combined) used to locate the target originated from the side on which the target was located. The only difference between experiments 1 and 3 was that in experiment 1 the auditory targeting cue was delivered by headphones, while in experiment 3 it was delivered by speakers. Experiment 2 was more difficult both in auditory perception and in processing. In this study the targeting cues came from in front of or behind the participant. Cues coming from in front of the participant meant the target was to the left, and conversely if the cue came from behind it meant that the target was to the right. The results of experiments 1 and 3 showed that when the signals originated from the sides, there was no difference in performance between the auditory and tactile targeting cues, whether by proximal or distal stimulation. However, in experiment 2, the participants were significantly slower to locate the target when using the auditory targeting cue than when using the tactile targeting cue, with nearly twice the losses when dual-tasking. No significant differences were found on performance of the shadowing task across the three experiments. The overall findings support the hypothesis that the characteristics of the sensory system itself influence the allocation of processing resources. For example, the differences in experiment 2 are likely due to front-back reversal, a common problem found with auditory stimuli located in front of or behind, but not with tactile stimuli.

Resumen
Les enfants prématurés reçoivent des stimulations sensorielles inappropriées lors d'une période critique de leur développement cérébral. Le toucher semble être une modalité clé chez les enfants prématurés. L'enjeu de ce travail de thèse était d'étudier les compétences tactiles manuelles précoces des enfants prématurés. Pour cela, nous nous sommes intéressés au traitement haptique (tactilo-kinesthésique) manuel de la forme des objets sans contrôle de la vision. Ce champ de recherche était resté jusqu'alors inexploré chez les enfants prématurés. Une première étude qui nous a servi d'étude pilote, nous a permis d'explorer les compétences (intra-main) à percevoir d'une main la différence entre deux formes d'objets (prisme vs. Cylindre) chez des enfants prématurés âgés de 33 à 34+6 SA (Semaines d'Aménorrhée). Dans une seconde étude, nous avons examiné l'évolution de ces compétences tactiles manuelles en fonction du degré de prématurité (trois groupes). Enfin, dans une troisième étude, nous avons étudié les compétences (inter-main) des enfants prématurés âgés de 33 à 34+6 SA à percevoir et mémoriser une forme d'objet avec une main et détecter une différence de forme avec l'autre main. Nos résultats révèlent l'existence d'une habituation et d'une discrimination manuelle de la forme des objets chez les enfants prématurés dès 28 SA. De plus, les enfants prématurés âgés de 28 à 34 SA présentent également des compétences de reconnaissance d'un objet familier suite à une interférence (présentation du nouvel objet) contrairement aux enfants âgés de plus de 34 SA. Les résultats particuliers de ce dernier groupe d'âge mettent en évidence des différences qualitatives avec les deux autres groupes de prématurité. Cependant les résultats ne montrent pas de différence quantitative des performances tactiles manuelles entre les trois groupes de prématurité. Enfin, les résultats révèlent qu'un transfert inter-manuel de la forme est présent chez les enfants prématurés témoignant de l'existence d'une communication entre les deux hémisphères cérébraux dès 33 SA. L'ensemble des résultats montre que l'enfant prématuré est déjà doté de compétences tactiles précoces. Ce travail de thèse apporte de nouvelles connaissances concernant le développement de la perception tactile et fournit des pistes de réflexion dans le cadre des soins de développement
Preterm infants receive inadequate sensory stimulations during a critical period of brain development. Touch seems to be a key modality in preterm infants. The aim of this thesis was to investigate early manual abilities in preterm infants. Therefore, we focused on manual haptic processing of object shape without vision control. This field of research remained hitherto unexplored in preterm infants. The first study investigated the abilities (intra-manual) to perceive in one hand the difference between the shape of two objects (prism vs. Cylinder) in preterm infants from 33 to 34+6 GW (Gestational Weeks). In a second study, we examined the development of these manual abilities depending on the degree of prematurity (three groups). Finally, in a third study, we investigated the abilities (inter-manual) of preterm infants from 33 to 34+6 GW to perceive and memorize an object's shape with one hand and to detect differences between two shapes in the opposite hand. Our results reveal that manual habituation and discrimination of object shape are present in preterm infants from 28 GW. In addition, preterm infants from 28 to 34 GW show recognition memory after haptic interference (presentation of a novel object) contrary to infants from 34 GW. This last result indicates qualitative differences between groups of prematurity. However, our results show no quantitative difference in manual performance between the three groups of prematurity. Finally, results reveal that an inter-manual transfer of shape information is present in preterm infants at 33 GW demonstrating the existence of communication between the two cerebral hemispheres. Overall, our results show that the preterm infant is already endowed with early tactile abilities. This thesis provides new theoretical insights concerning the development of tactile perception and opens new perspectives in the context of developmental care

Resumen
La pseudonegligence observee chez les normaux (bowers et heilman, 1980) consiste a repondre a gauche du centre objectif quand on demande de partager des lignes horizontales par le milieu. Certains l'expliquent par la nature spatiale de la tache qui, en activant l'hemisphere d, entrainerait un "surdimensionnement" de la partie g du stimulus. Mais son instabilite souligne aussi la puissance du biais d'orientation vers la d. D'autres pensent que le sens de l'exploration determine celui des deviations, ou invoquent un amorcage de l'attention du cote ou debute l'exploration. Nous avons teste l'hypothese de l'existence dans cette tache de composantes sensorielle et motrice s'exercant en sens inverse. Nos resultats ne confirment pas la pseudonegligence et ne montrent pas de difference entre les sujets aveugles et voyants. Chaque main devie dans l'hemiespace controlateral. D'autre part, si on impose toujours le meme sens d'exploration, les deviations suivent ce sens. Mais, lorsqu'on amorce lateralement l'attention avant l'exploration, les erreurs sont attirees du cote de l'amorcage. La discussion porte sur la theorie d'activation hemispherique et sur l'hypothese d'un decalage du referentiel egocentre
Bowers and heilman (1980) observed that when righthanded adults were asked to locate, in the hapic modality, the midpoint of a horizontal line, both hands tended to deviate to the left of the true midpoint. This error, called "pseudoneglect" by reference to the rightward error of patients suffering from right posterior brain lesions, was also observed in vision and has been explained by hemispheric activation theories. Because bisection is spatial in nature, it would activate the right hemisphere and would therefore induce a left lateral shift of attention. In our research on bisection in the haptic modality of normal blindfolded and totally blind adults, we first replicated bowers and heilman's results (sampaio & philip, 1991). But further studies failed to confirm the existence of pseudoneglect. Actually, each hand tended to deviate in the contralateral space. In addition, when the direction of exploration of the line to be bisected was constrained (from left-to-right only, or from right-to-left), the responses were deviated in the direction of the arm movement. Finally, attentional priming of one end of the stimulus tended to deviate the subjective midpoint in the direction of the lateral cue. These results are discussed in relation to hemispheric activation theories and to the hypothesis assuming changes in the egocentric reference frame

Resumen
Ce travail s'inscrit dans le cadre d'une approche comparative de la perception haptique chez l'homme et le babouin. Chez les primates, la motricite digitale fine est sous le controle de l'hemisphere controlateral. La comparaison des competences de chaque main, chez des sujets humains droitiers, met generalement en evidence une superiorite de la main gauche (hemisphere droit) dans la reconnaissance d'objets explores tactilement. Cependant, bien que l'activite exploratoire de la main semble jouer un role critique dans les capacites perceptives, les relations entre la lateralisation hemispherique et les procedures d'exploration manuelle ont jusqu'ici ete negligees. L'existence d'asymetries manuelles similaires chez les primates non humains au cours de la perception haptique des objets reste sujet a controverses en raison de l'insuffisance des donnees disponibles. Grace a une approche originale, permettant d'analyser les contacts de la main sur les objets au cours de la perception haptique, nous avons etudie, chez l'homme et chez le babouin, les asymetries manuelles non seulement dans le niveau de performance atteint mais aussi dans les strategies d'exploration adoptees par chaque main. Les resultats de trois experiences menees chez des sujets humains droitiers, montrent que: (1) la main droite et la main gauche utilisent des procedures exploratoires differentes, susceptibles de refleter des processus de traitement propres a chaque hemisphere ; (2) ces differences sont plus importantes chez les sujets masculins que feminins ; (3) les asymetries mises en evidence dans les strategies d'exploration peuvent echapper a une analyse restreinte au seul niveau de la performance ; (4) les strategies d'exploration manuelle sur les objets sont determinees par les contraintes biomecaniques que la tache impose a la motricite manuelle et par les modes de traitement propres a chaque hemisphere. Deux experiences ont ete menees chez le babouin. La premiere est une experience preliminaire centree sur les preferences manuelles d'un groupe de babouins dans deux epreuves de discrimination tactilo-kinesthesique. Dans la seconde experience, mettant en uvre un dispositif identique a celui utilise chez l'homme, nous avons observe une superiorite de la main gauche chez deux babouins soumis a une tache de discrimination tactilo-kinesthesique complexe entre deux objets. Cet avantage pourrait etre lie a une periode d'exploration plus longue de la main gauche que de la main droite. Bien que les differences de procedure entre les experiences menees avec les sujets humains et les babouins limitent la portee d'une comparaison des deux especes, les resultats obtenus restent compatibles avec l'idee d'une homologie des mecanismes de la perception haptique chez les primates humains et non humains

Resumen
In this chapter, the extent to which actions and perceptions depend on each other is explored particularly for the visual system. Viewing the world through a mirror or a lens that displaces or inverts images provides examples of our ability to learn new sensorimotor consistencies. The use of sensory prostheses that replace one sensory modality with another, for example, visual by tactile stimuli or vestibular by tactile stimuli, provides examples of the capacity of our brains to learn about new sensorimotor relationships, often with surprising rapidity, even in an adult.

Resumen
This article discusses the impact of eugenics in Britain. It discusses eugenics as a biological way of thinking about social, economic, political, and cultural change. It gives scientific credibility to prejudices, anxieties, and fears that are prevalent primarily among the middle and upper classes. It delineates the tensions between “classic” and “reform”, although this is only one modality along which to align the complex factors that polarized the society—some of them ideological, some of them about tactics, and some based on personalities. It gives a detailed description of the differentiation of societies' activities into study and practice. The social problem group; research into contraceptive methods; family allowances; race mixture; and immigration are discussed. The practices are divided into negative and positive. Finally, this article concludes that eugenicists see feeblemindedness as hereditary, emblematic of degeneracy, and contributes to numerous social problems, such as poverty and unemployment.

Resumen
The concept of tactile working memory indicated that the system can actively maintain (maintenance) and flexibly manipulate (manipulation) tactile information received from the body surface. The cognitive processes consisted of providing for the interim integration, processing, disposal, and retrieval of information. In this review, we combined psychophysical and neurophysiological experiments to highlight some of the most important characteristics and the neural substrates of tactile working memory. In particular, these studies have addressed how neural codes are related to perception and working memory in tactile modality. Tactile information is stored by segregated neural networks that include not only the prefrontal and parietal cortex, but also the somatosensory areas where relatively early stages of perceptual processing are carried out and past and current sensory information are combined to drive higher cortical areas.

Resumen
When a user integrates a sensory substitution device into her life, the process involves perceptual learning, that is, ‘relatively long-lasting changes to an organism’s perceptual system that improve its ability to respond to its environment’. In this chapter, I explore ways in which the extensive literature on perceptual learning can be applied to help improve sensory substitution devices. I then use these findings to answer a philosophical question. Much of the philosophical debate surrounding sensory substitution devices concerns what happens after perceptual learning occurs. In particular, should the resultant perceptual experience be classified in the substituted modality (as vision), in the substituting modality (as auditory or tactile), or in a new sense modality? I propose a novel empirical test to help resolve this philosophical debate.

Resumen
This chapter explores the relationship between sensory substitution devices and the training of attention. Sensory substitution devices, typically used by the blind, deliver information about the environment by converting the information normally received through one sense (e.g., vision) into information for another sense (e.g., audition or touch). When a user integrates a sensory substitution device into her life, the integration process involves perceptual learning. This chapter explores two questions. First, in what ways can sensory substitution illuminate how the training of attention works more generally? Second, how does knowledge of the way attention is trained in perceptual learning help us to better understand sensory substitution? The chapter draws on findings in these areas to answer a philosophical question: Should the post-perceptual learning experience be classified in the substituted modality (e.g., as vision), in the substituting modality (e.g., as auditory or tactile), or in a new sense modality?

Resumen
In a current academic architectural design culture often characterized by parametricism, cybernetics, and virtual reality, architectural design’s visceral and haptic dimensions have assumed an inferior position in architectural design ideation and process. Whether through intentional dismissal or benign neglect, the design process pursued in many undergraduate architectural programs has assumed an occularcentric modality. Students ideate in a weightless, immaterial, design landscape of simulation, devoid of the shifting qualities of color, light and shadow, the nuance of olfactory and tactile cues, and material resonance. Rather than advance a nostalgic, anti-digitally mediated position, the design practices described here deploy haptic means to tender a design process that advances a tactile tectonic grounded in the DNA or patterns of human experience and nature.

Resumen
A surface texture is a common design factor that affects a customer’s sensory perception of product quality. Customers perceive a surface quality using multiple sensory modalities, for example, vision and touch, and switch them through an interaction with a product, for example, a transition from vision to touch. Between such sensory modality transitions, human beings often predict subsequent modal perceptions using a prior modality, for example, predicting the tactile quality of a product from its appearance before actually touching it. We believe that a disconfirmation between prediction using a modality and an experience using another modality affects a perceived quality. In this paper, we propose a method to evaluate the quality of a surface texture with attention to the effects of a disconfirmation between a prior visual prediction and posterior tactual experience. To identify the textural factors contributing to such an effect, we conducted a sensory evaluation experiment with combinations of visual and tactile texture samples that were synthesized using a half-mirror. We demonstrate the appropriateness of the method with analysis of the results of an experiment using fourteen plastic texture samples having different textures that are commonly used in a product design.

Resumen
Multimedia languages traditionally, they focus on synchronizing a multimedia presentation (based on media and time abstractions) and on supporting user interactions for a single user, usually limited to keyboard and mouse input. Recent advances in recognition technologies, however, have given rise to a new class of multimodal user interfaces (MUIs). In short, MUIs process two or more combined user input modalities (e.g. speech, pen, touch, gesture, gaze, and head and body movements) in a coordinated manner with output modalities . An individual input modality corresponds to a specific type of user-generated information captured by input devices (e.g. speech, pen) or sensors (e.g. motion sensor). An individual output modality corresponds to user-consumed information through stimuli captured by human senses. The computer system produces those stimuli through audiovisual or actuation devices (e.g. tactile feedback). In this proposal, we aim at extending the NCL multimedia language to take advantage of multimodal features.

Resumen
In the user’s perception of a product’s qualities, the state of their sensory modality may shift from one state to another. For example, users see and then touch a product to perceive its texture. Between such state transitions, users have expectations regarding their subsequent states based on their experience of a current state event. Expectation effect is a psychological effect in which prior expectation changes posterior perception itself. The effect is a key factor to design user’s emotions induced by expectation disconfirmation as well as designing a perceived quality based on prior expectations. Although experimental findings on the expectation effect exist in a variety of research disciplines, general and theoretical models of the effect have been largely neglected. The present authors previously found out the visual expectation effect on tactile perceptions of surface texture. The causes of the expectation effect, however, remain largely unexplored. To intentionally design the expectation effect, general and theoretical models that estimates conditions of the effect is needed. In this paper, we propose a theoretical model of the expectation effect using information theory and an affective expectation model (AEM). We hypothesize that Shannon’s entropy of the prior subjective probability distributions of posterior experience determines the occurrence of the expectation effect and that the amount of information gained after experiencing a posterior event is positively correlated with the intensity of the expectation effect. We further hypothesize that a conscious level of expectation discrepancy distinguishes between two types of expectation effect, namely, assimilation and contrast. To verify these hypotheses, we conducted an experiment in which participants responded to the tactile qualities of surface texture. In the experiment, we extracted the visual expectation effect on tactile roughness during a sensory modality transition from vision to touch and analyzed the causes of the effect based on our hypotheses. The experimental results indicated the appropriateness of the proposed model of the expectation effect.

Resumen
Informal learning environments (ILEs) like museums incorporate multi-modal displays into their exhibits as a way to engage a wider group of visitors, often relying on tactile, audio, and visual means to accomplish this. Planetariums, however represent one type of ILE where a single, highly visual presentation modality is used to entertain, inform, and engage a large group of users in a passive viewing experience. Recently, auditory displays have been used as a supplement or even an alternative to visual presentation of astronomy concepts, though there has been little evaluation of those displays. Here, we designed an auditory model of the solar system and created a planetarium show, which was later presented at a local science center. Attendees evaluated the performance on helpfulness, interest, pleasantness, understandability, and relatability of the sounds' mappings. Overall, attendees rated the solar system and planetary details very highly, in addition to providing open-ended responses about their entire experience.

Resumen
With advancements in surgical techniques, patients have experienced improvements in health and recovery outcomes. However, about 87% of laparoscopic surgeons [1] and an increasing number of surveyed allied health professionals [2, 3] report musculoskeletal symptoms. Medical practitioners and human factors engineers have highlighted the “hostile” and “dangerous” operating room (OR) environment [1, 4, 5]. With increasing technology and surgical case complexity, physical demands for surgical team members will continue to increase due to circumstances such as technology restricting posture, taking up working space and more team members working around smaller surgical incisions [6]. There is widespread concern that these medical professionals’ work is unsustainable for safe and healthy patients and surgical team members. Surgical team members can benefit from posture improvement during surgery; however, direct postural feedback may be difficult during their work due to the high visual and auditory stimuli during surgery. The tactile modality has been recently explored as a method to provide additional information without interfering with cognitive resources dedicated to visual and auditory pathways [7]. Tactile devices have successfully been implemented in high-stress environments, e.g., military, healthcare, and rehabilitation with a resulting improvement in performance [8–11]. Vibrotactile feedback has been specifically implemented in the healthcare field for improved performance by 31–75% anesthesiologists during simulated tasks [10]. Additionally, it has contributed to improved postural control in rehabilitation patients[11]. Despite success in other application areas, the potential of tactile devices for improving healthcare workers’ safety and performance remains unexplored. This study is a part of a larger project to design a wearable device that provides realtime vibrotactile feedback for preventing fatigue and musculoskeletal disorders for healthcare workers in the workplace. This specific aim of this study is to measure distraction, frustration, and performance during a surgical simulation task performed with and without vibrotactile feedback. This is a test of initial feasibility of vibrotactile feedback for use in training proper ergonomics for surgical team members. The researchers hypothesize that there will be some distraction with the vibrotactile feedback wearable but no frustration or performance degradation during the basic simulation task.

Resumen
A deviation of reality from our prior expectation causes positive or negative emotions such as unexpected pleasure or disappointment depending on the condition. Although recognition of this psychological phenomenon has much potential in the design of a product’s emotional quality, i.e., that which evokes the customer’s specific feelings, impressions, or emotions, this factor is largely unexplored. In the transition from prior expectation to posterior experience, we often observe switching sensory modalities, such as from vision to touch. In this paper, we discuss the differences in emotional quality between different sensory modalities in the context of shifting from visual expectation to somatosensory experience. As a case study, we investigate the effects of an object’s surface characteristics on the deviation from visual expectation in the context of “lifting an object”. In this context, the sensory modality shifts from vision to touch and vision, i.e., we see and then lift a target object. We conducted an experiment using cylinder-shaped objects of equal weight with different surface characteristics such as brightness, roughness and gloss. The experiment consists of three phases. 1) We asked eight participants to give their impressions by only looking at the object using adjectives and onomatopoeias, 2) we asked them to lift the objects and recorded their grip force, and 3) we conducted the same evaluation as the first phase except that the participants were allowed to pick up the objects. The results show that the deviation from visual prediction regarding object massiveness and surface roughness can be observed using redundant grip force differences, and that this deviation affects a posteriori tactile emotional qualities such as tactile feelings. With the result, we discuss the need to consider such deviations in emotional quality design.
