This immersive VR system developed in Unity served to explore transformations of the virtual hand space that allow reduced arm strain in repetitive tasks – in particular overhead manipulation tasks, while preserving the illusion of body ownership.
Motion tracking for the user’s right hand is supported by two LeapMotion sensors, which are attached to the head mounted display (HTC Vive). To improve interaction and enhance the body ownership illusion, a vibration motor (LRA) on the user’s right index finger provides tactile feedback when touching virtual objects.
This system served as prototype for the experiments presented in the publication Ownershift: Facilitating Overhead Interaction in Virtual Reality with an Ownership-Preserving Hand Space Shift.
