Here's looking at you: A Spherical FTVR Display for Realistic Eye-Contact
2018
In this work we describe the design, implementation and initial evaluation of a spherical Fish Tank Virtual Reality (FTVR) display for realistic eye-contact. We identify display shape, size, and depth cues as well as model fidelity as important considerations and challenges for setting up realistic eye-contact and package it into a reproducible framework. Based on the design, we implemented and evaluated the system to assess the effectiveness of the eye-contact. In our initial evaluation participants were able to identify eye-contact with an accuracy of 89.6%. Moreover eye-contact with a virtual character triggered changes in participant's social behavior that are in line with real world eye-contact scenarios. Taken together, these results provide practical guidelines for building displays for realistic eye-contact and can be applied to applications such as teleconferencing and VR treatment in psychology.
