Paper Abstract

The goal of this research is to compare the performance of different stereoscopic displays and tracking/interaction devices in the context of motor behavior and interaction quality within various Virtual Reality (VR) environments. Participants were given a series of VR tasks requiring motor behaviors with different degrees of freedom. The VR tasks were performed using a monoscopic display and two stereoscopic displays (shutter glasses and autostereoscopic display) and two tracking devices (optical and magnetic). The two 3D tracking/ interaction devices were used to capture continuous 3D spatial hand position with time stamps. Participants completed questionnaires evaluating display comfort and simulation fidelity among the three displays and the efficiency of the two interaction devices. The trajectory of motion was reconstructed from the tracking data to investigate the user's motor behavior. Results provide information on how stereoscopic displays can affect human motor behavior and interaction modes during VR tasks. These preliminary results suggest that the use of shutter glasses provides a more immersive and user-friendly display than autostereoscopic displays. Results also suggest that the optical tracking device, available at a fraction of the cost of the magnetic tracker, provides similar results for users in terms of functionality and usability features.
