Abstract

Virtual reality allows users to immerse themselves into an alternate reality. Science fiction books and films, like Ready Player One, have represented the interaction with virtual reality as a body and mind immersion, where the user is able to move freely, interact with objects and feel the surrounding environment like in the real world. Although we are not there yet, advances in technology are bringing us closer to this vision. One of which, is the advancement in dielectric elastomers sensors (DES). By integrating DES into a wetsuit to capture shoulder and elbow motion, we are able to replicate the movement in a virtual reality humanoid avatar. Compared to the elbow motion, which can be modelled as extension and flexion motions, the shoulder joint is much more complex with a greater number of degrees of freedom. In this paper we present a wetsuit with 5 dielectric elastomer sensors that captures the elbow flexion/extension, shoulder flexion/extension, abduction/adduction and rotation with an RMSE of 11.8°, 5.2°, 5.4° and 7.9° respectively.
