  • FEELTECH Wear: Enhancing Mixed Reality Experience with Wrist to Finger Haptic Attribution

    R Umehara, H Taguchi, A Horie, Y Kamiyama, S Sakamoto, H Ishikawa, ...

    ACM SIGGRAPH 2024 Emerging Technologies, 1-2  2024.07

    　View Summary

    FEEL TECH Wear is a system that facilitates haptic interactions while keeping most of the palm free, by presenting directional force through rotational skin-stretch distribution feedback to the wrist and providing texture sensation through vibration feedback to the fingertips. With advancements in hand tracking and passthrough technologies, hand interactions in Mixed Reality (MR) environments have become more accessible, necessitating palm-free haptic feedback methods that do not hinder interactions with real objects or impair vision-based hand tracking. The hardware of FEEL TECH Wear primarily consists of two components: a hand-mounted device for each hand and a control unit located at the back of the head. The hand-mounted device is equipped with four channels of rotational skin-stretch tactors at the wrist and vibration tactors at the thumb and index finger. Using FEEL TECH Wear, three applications have been realized: haptic feedback for virtual objects, haptic augmentation for real objects, and haptic guidance towards objects.

  • The Malleable-Self Experience: Transforming Body Image by Integrating Visual and Whole-Body Haptic Stimuli

    T Person, N Hanamitsu, D Hynds, S Wakisaka, K Isobe, L Mochizuki, ...

    ACM SIGGRAPH 2024 Emerging Technologies, 1-2  2024.07

    　View Summary

    The Malleable-Self Experience comprises the integration of the visual element of virtual reality (VR) with the whole-body haptic sensations of the Synesthesia X1 haptic chair. The goal is to induce a provocative experience that expands one's understanding of the self by creating a malleable perception of the body image. We explore the effects of visual and whole-body haptic integration on augmenting body image during dynamic transformations of visual representations of the body in VR. We design the plausibility of these perceptual augmentations using a specific sequence of multisensory events: (1) establishing body ownership of a virtual body anchored in the same self-located space as the participant, (2) separating the virtual body to hover above the participant's physical body, enhanced by accompanying haptic stimuli to increase proprioceptive uncertainty, and (3) transforming the virtual body with integrated visuo-haptic stimuli to sustain perceptual congruency.

  • HaptoRoom: Using Vibrotactile Floor Interfaces To Enable Reconfigurable Haptic Interaction Onto Any Furniture Surfaces

    K Tsujita, T Yoshida, K Kobayashi, A Horie, N Hanamitsu, K Minamizawa

    ACM SIGGRAPH 2024 Emerging Technologies, 1-2  2024.07

    　View Summary

    Vibrotactile interaction is an essential source of HCI and should be on a large scale, such as room scale, whereas in the past many devices have been small. However, there is a practical difficulties for implementing vibrotactile actuators and sensors to every furnitures in the room. To address this problem, our approach, HaptoRoom, archives reconfigurable ubiquitous haptic interaction to existing furniture without additional equipment by installing actuators only in the floor. A user can design detailed spatial distribution of vibrotactile pattern, leveraging with multi-point individual control of actuators array inside floor interfaces.

  • Cymatics Cup: Shape-Changing Drinks by Leveraging Cymatics

    W Chen, Y Yang, KH Liu, YS Pai, J Yamaoka, K Minamizawa

    Proceedings of the CHI Conference on Human Factors in Computing Systems, 1-19  2024.05

    　View Summary

    To enhance the dining experience, prior studies in Human-Computer Interaction (HCI) and gastrophysics have demonstrated that modifying the static shape of solid foods can amplify taste perception. However, the exploration of dynamic shape-changing mechanisms in liquid foods remains largely untapped. In the present study, we employ cymatics, a scientific discipline focused on utilizing sound frequencies to generate patterns in liquids and particles-to augment the drinking experience. Utilizing speakers, we dynamically reshaped liquids exhibiting five distinct taste profiles and evaluated resultant changes in taste perception and drinking experience. Our research objectives extend beyond merely augmenting taste from visual to tactile sensations; we also prioritize the experiential aspects of drinking. Through a series of experiments and workshops, we revealed a significant impact on taste perception and overall drinking experience when mediated by cymatics efects. Building upon these findings, we designed and developed tableware to integrate cymatics principles into gastronomic experiences.

  • People with Disabilities Redefining Identity through Robotic and Virtual Avatars: A Case Study in Avatar Robot Cafe

    Y Hatada, G Barbareschi, K Takeuchi, H Kato, K Yoshifuji, K Minamizawa, ...

    Proceedings of the CHI Conference on Human Factors in Computing Systems, 1-13  2024.05

    　View Summary

    Robotic avatars and telepresence technology enable people with disabilities to engage in physical work. Despite the recent popularity of the metaverse, few studies have explored the use of virtual avatars and environments by people with disabilities. In this study, seven disabled participants working in a cafe where remote customer service is provided via robotic avatars, were engaged in the development and use of personalized virtual avatars displayed on a large screen in-situ in combination with existing physical robots, creating a hybrid cyber-physical space. We conducted longitudinal semi-structured interviews to investigate the psychological changes experienced by the participants. The results revealed that mass-produced robotic avatars allowed participants to not disclose their disability if they did not want to, but also backgrounded their identities; by contrast, customized virtual avatars shaped without physical constraints, highlighted their personalities. The combined use of robotic and virtual avatars complemented each other and can support pilots in redefining their identity.

    　View Summary

    <p>Information technologies, such as IoT, artificial intelligence (AI), and virtual reality (VR), have seen so much development that there is now a wide variety of digital equipment incorporated into the infrastructure of daily life. From the agrarian society (Society 1.0) through the information society (Society 4.0), humankind has created farmlands and cities by structuring natural environments physically and has built information environments by structuring them informationally. However, despite the rapid development of information environments, it may be fair to say that the perspectives of the human body have not changed at all since the industrial revolution.</p><p>In the context of these recent technological developments, greater attention is being paid to human augmentation studies. These studies aim for a new embodiment of “human-computer integration,” one which can physically and informationally compensate or augment our innate sensory functions, motor functions, and intellectual processing functions by using digital equipment and information systems at will, as if they were our hands and feet. It has also been proposed that the technical systems that enable us to freely do what we want by utilizing human augmentations be called “JIZAI” (freedomization) as opposed to “automation.”</p><p>The term “JIZAI body” used in these studies represents the new body image of humans who will utilize engineering and informatics technologies to act at will in the upcoming “super smart society” or “Society 5.0.” In these studies, human augmentation technologies are an important component of JIZAI, but JIZAI is not the same as human augmentation. JIZAI is different in scope from human augmentation, as it aims to enable humans to move freely among the five new human body images: “strengthened sense” (augmented perception), “strengthened physical body” (body augmentation), “separately-designed mind and body” (out of body transform), “shadow cloning,” and “assembling.” In the society of the future where JIZAI bodies widely prevail, we will use technologies that enable us to do what we have failed at or given up due to limitations of our physical bodies. We believe that a future society, one in which aging does not reduce our capabilities but instead increased options give us hope, can be realized. This special issue, consisting of two review papers and twelve research papers, deals with diverse and wide-ranging areas, including human augmentation, robotics, virtual reality, and others. We would like to express our sincere appreciation to all the authors and reviewers of the papers contributed to this special issue and to the editorial committee of the Journal of Robotics and Mechatronics for their gracious cooperation.</p>

    　View Summary

    In this study, with the aim of constructing a "body conjugate system" that projects our body image to control targets in various shapes, we studied on design guidelines and design limits of the body conjugate system by using VR avatars and wearable robots. We examined our cognition on the body conjugate system in the case of constructing it with not only the whole body but also with the local elements of the body. As a result of this study, we acquired the concept of "body schema editing" according to physical tasks.
