Deictic Pointing in Collaborative Virtual Reality Environments

Master thesis at Institut für Visualisierung und Interaktive Systeme (VIS) Universität Stuttgart, Germany.


Virtual reality headsets are becoming more accessible to users. This accessibility opened room in the market for various applications that are social or include multi-player elements. Interactions between users in virtual reality is becoming a key element. However, most collaborative VR applications have inaccurate representations of users’ behavior and lack seamless interaction between users. These limitations could negatively influence communication between two users inside VR. In this work, we propose a novel approach where accurate visual and behavioral representation of users within a collaborative VR environment was made possible. A study was conducted to evaluate the approach by making participants use deictic pointing gestures to communicate with one another. The results confirm that the user communication through the proposed approach has been successful.
