Motion Control in VR — Real-time Upper Limb Tracking via IMU and Flex Sensor

Real-time limb motion tracking offers a natural and intuitive way to interact with virtual environment in VR head-mounted displays. In this report, we present an affordable while accurate and lowlatency tracker design using a single IMU plus a flex sensor. A kinematically-constrained model is developed to fuse the 7-degree measurement and reconstruct the state of upper limb. We build a prototype together with a third person shooting game to demonstrate the effectiveness of our design.
