GravityCup: a liquid-based haptics for simulating dynamic weight in virtual reality

During interaction in a virtual environment, haptic displays provide users with sensations such as vibration, texture simulation, and electrical muscle stimulation. However, as humans perceive object weights naturally in daily life, objects picked up in virtual reality feel unrealistically light. To create an immersive experience in virtual reality that includes weight sensation, we propose GravityCup, a liquid-based haptic feedback device that simulates realistic object weights and inertia when moving virtual handheld objects. In different scenarios, GravityCup uses liquid to provide users with a dynamic weight sensation experience that enhances interaction with handheld objects in virtual reality.
