    Realistic Impact Method with Force Feedback in VR Space Using a Lower Limb Exoskeleton Device
    (The Eurographics Association, 2025) Kanta, Ogura; Shimizu, T.; Sugino, T.; Sawahashi, R.; Nishihama, R.; Nakamura, T.; Garro, Valeria; Young, Gareth; Elwardy, Majed
    In recent years, the widespread adoption of Head-Mounted Displays (HMDs) has made Virtual Reality (VR) experiences more accessible, leading to the development of force-feedback devices to enhance immersion. Force-feedback devices enhance VR immersion but presenting large, realistic forces, such as for a soccer kick, is challenging due to safety constraints. Therefore, designing the presented reaction force is crucial to enhance realism and mitigate perceptual discrepancies. In this study, we used a lower limb-mounted force-feedback device to investigate how different torque waveforms presented during a ball kick affect user perception.

    Spatial Body Augmentation for Destructive Interaction in Giant Avatar Embodiment using a Wearable Force Feedback Device
    (The Eurographics Association, 2025) Sawahashi, Ryunosuke; Nishihama, R.; Nakamura, T.; Garro, Valeria; Young, Gareth; Elwardy, Majed
    This study examined the effects of force presentation on physicality in a VR environment using a giant avatar. Focusing on a sense of body ownership (SoB) and a sense of agency (SoA), we designed an interaction in which the user's upper limb movements are synchronized with the arm movements of a giant avatar to destroy a building using a wearable force-sensing device. The device combines a magneto-viscous fluid brake and a vibration motor, and is capable of presenting inertial forces and a sense of collision in response to joint acceleration. Experimental results showed that the device improved the sense of weight and the sense of destruction while maintaining the sense of body ownership and the sense of agency.
