Eye-Gaze Tracking-Based Telepresence System for Videoconferencing

摘要

An approach to the teleimmersive videoconferencing system enhanced by the pan-tilt-zoom (PTZ) camera, controlled by the eye-gaze tracking system, is presented in this paper. An overview of the existing telepresence systems, especially dedicated to videoconferencing is included. The presented approach is based on the CyberEye eye-gaze tracking system engineered at the Multimedia Systems Department (MSD) of Gdansk University of Technology (GUT), as well as on a standard PTZ security camera communicating with the computer by the TCP/IP protocol. Technical aspects of the developed system prototype including two different use cases (one-way and two-way configuration of system) are described. Moreover, a discussion related to the gathered user's experience as well as to difficulties and opportunities concerning the proposed approach are included.
