Autonomic gaze control of avatars using voice information in virtual space voice chat system

چکیده
Avatars play an important role for the embodiment of the users in virtual space communication systems. However, the conventional systems to realize the gaze have required camera-based precise eye tracking and the numbers of the users have been restricted. This paper proposes a simple substitution for the gaze control in a virtual space voice chat system. The method is to control the gaze target of the avatar based on the Appeal Point that is calculated from the voice levels of the other users. The subjective evaluation experiment demonstrated the effectiveness of the method on the naturalness of the virtual space communication.

Modern eye tracking technology allows an observer’s gaze to be determined in realtime by measuring their eye movements. Recent studies have examined the viability of using gaze data as a means of controlling computer games. This paper investigates the combination of gaze and voice recognition as a means of hands-free interaction in 3D virtual environments. A novel game evaluation framework is i...

متن کاملSimulation versus Reproduction for Avatar Eye-Gaze in Immersive Collaborative Virtual Environments
Using video technology in telecommunication systems poses spatial orientation problems because participants have a window onto each other’s space, rather than sharing one space. These problems can be overcome using immersive virtual reality in which remote participants are represented as avatars. Because of the challenges involved in capturing eyegaze reliably and problems of loss in transmissi...
