Embodied Tentacle: Mapping Design to Control of Non-Analogous Body Parts with the Human Body Open
Manipulating a non-humanoid body using a mapping approach that translates human body activity into different structural movements enables users to perform tasks that are difficult with their innate bodies. However, a key challenge is how t…

Effects of self-avatar cast shadow and foot vibration on telepresence, virtual walking experience, and cybersickness from omnidirectional movie Open
Human locomotion is most naturally achieved through walking, which is good for both mental and physical health. To provide a virtual walking experience to seated users, a system utilizing foot vibrations and simulated optical flow was deve…

Investigating the perceptual attribution of a virtual robotic limb synchronizing with hand and foot simultaneously Open
Introduction: Incorporating an additional limb that synchronizes with multiple body parts enables the user to achieve high task accuracy and smooth movement. In this case, the visual appearance of the wearable robotic limb contributes to t…

Temporal visuomotor synchrony induces embodiment towards an avatar with biomechanically impossible arm movements Open
Visuomotor synchrony in time and space induces a sense of embodiment towards virtual bodies experienced in first-person view using Virtual Reality (VR). Here, we investigated whether temporal visuomotor synchrony affects avatar embodiment …

Effect of connection induced upper body movements on embodiment towards a limb controlled by another during virtual co-embodiment Open
Even if we cannot control them, or when we receive no tactile or proprioceptive feedback from them, limbs attached to our bodies can still provide indirect proprioceptive and haptic stimulations to the body parts they are attached to simpl…

Shared Avatar for Hand Movement Imitation: Subjective and Behavioral Analyses Open
Virtual co-embodiment enables sharing avatars with others in virtual environments and can be applied for training motor skills by allowing teachers to share movements with learners in first-person perspective. We conducted a task where par…

MultiSoma: Motor and Gaze Analysis on Distributed Embodiment With Synchronized Behavior and Perception Open
Human behavior and perception are optimized for a single body. Yet, the human brain has plasticity, which allows us to extend our body schema. By utilizing technology like robotics or virtual reality (VR), we can modify our body parts or e…

Knowing the intention behind limb movements of a partner increases embodiment towards the limb of joint avatar Open
We investigated whether sharing a common goal with a partner and knowing the partner’s intention behind arm movements affect the senses of agency and ownership towards an arm fully controlled by the partner. Participant dyads controlled di…

Cyborgs, Human Augmentation, Cybernetics, and JIZAI Body Open
We propose a concept called "JIZAI Body" that allows each person to live the way they wish to live in society. One who acquires a JIZAI Body can (simultaneously) control (or delegate control) of their natural body and extensions of it, bot…

Embodiment of Supernumerary Robotic Limbs in Virtual Reality Open
The supernumerary robotic limb system expands the motor function of human users by adding extra artificially designed limbs. It is important for us to embody the system as if it is a part of one’s own body and to maintain cognitive transpa…

The effects of body direction and posture on taking the perspective of a humanoid avatar in a virtual environment Open
Visual perspective taking is inferring how the world looks to another person. To clarify this process, we investigated whether employing a humanoid avatar as the viewpoint would facilitate an imagined perspective shift in a virtual environ…

Virtual Mirror and Beyond: The Psychological Basis for Avatar Embodiment via a Mirror Open
In virtual reality (VR), a virtual mirror is often used to display the VR avatar to the user for enhancing the embodiment. The reflected image of the synchronization of the virtual body with the user’s movement is expected to be recognized…

Illusory body ownership of dynamic invisible body is not associated with multimodal changes in body perception Open
Illusory body ownership to a virtual body is induced by synchronous movements of own body and the virtual body. This illusion can be induced by the synchronous movement of only the hands and feet (Kondo et al., 2018). Here, we examined whe…

Peripersonal space in the front, rear, left and right directions for audio-tactile multisensory integration Open
Peripersonal space (PPS) is important for humans to perform body–environment interactions. However, many previous studies only focused on the specific direction of the PPS, such as the front space, despite suggesting that there were PPSs i…

Enhancing Virtual Walking Sensation Using Self-Avatar in First-Person Perspective and Foot Vibrations Open
Walking is a fundamental physical activity in humans. Various virtual walking systems have been developed using treadmill or leg-support devices. Using optic flow, foot vibrations simulating footsteps, and a walking avatar, we propose a vi…
