MetamorphX: An Ungrounded 3-DoF Moment Display that Changes its Physical Properties through Rotational Impedance Control
Takeru Hashimoto, Shigeo Yoshida, Takuji Narumi
Humans can estimate the properties of wielded objects (e.g., inertia and viscosity) using the force applied to the hand. We focused on this mechanism and aimed to represent the pro…
The Effect of Photorealism Consistency between the Virtual Hands and Environment on the Sense of Body Ownership and Presence in Virtual Reality
Nami Ogawa, Takuji Narumi
Virtual reality (VR) technology allows users to feel a virtual body as if it was their own (i.e., body ownership illusion). Previous studies have explored how the visual realism of…
Leveraging Tendon Vibration to Enhance Pseudo-Haptic Perceptions in VR
Yutaro Hirao, Tomohiro Amemiya, Takuji Narumi +2
Pseudo-haptic techniques are used to modify haptic perception by appropriately changing visual feedback to body movements. Based on the knowledge that tendon vibration can affect o…
Revisiting Walking-in-Place by Introducing Step-Height Control, Elastic Input, and Pseudo-Haptic Feedback
Yutaro Hirao, Takuji Narumi, Ferran Argelaguet +1
Walking-in-place (WIP) is a locomotion technique that enables users to "walk infinitely" through vast virtual environments using walking-like gestures within a limited physical spa…
Visual-Tactile Cross-Modal Data Generation using Residue-Fusion GAN with Feature-Matching and Perceptual Losses
Shaoyu Cai, Kening Zhu, Yuki Ban +1
Existing psychophysical studies have revealed that the cross-modal visual-tactile perception is common for humans performing daily activities. However, it is still challenging to b…
Virtual Co-Embodiment: Evaluation of the Sense of Agency while Sharing the Control of a Virtual Body among Two Individuals
Rebecca Fribourg, Nami Ogawa, Ludovic Hoyet +4
In this paper, we introduce a concept called ''virtual co-embodiment'', which enables a user to share their virtual avatar with another entity (e.g., another user, robot, or autono…
Redirection Controller Using Reinforcement Learning
Yuchen Chang, Keigo Matsumoto, Takuji Narumi +2
There is a growing demand for redirected walking (RDW) techniques and their application. To apply appropriate RDW methods and manipulation, the RDW controllers are predominantly us…
