Abstract

Creating virtual characters with natural movements is a challenging problem. Users are very aware of how people in general move when interacting based on a lifetime of experience. Unintentionally unnatural movements can adversely affect the experience of the participant. Computationally intensive techniques for calculating dynamic movements can cause the system to run slowly, reducing the frame rate or the performance of the avatar within the simulation. Our system provides a simple implementation that enables precise individual control of multiple avatars.

Animating Gaze Shifts for Virtual Characters Based on Head Movement Propensity
VS-GAMES '10: Proceedings of the 2010 Second International Conference on Games and Virtual Worlds for Serious Applications

An automatic model is presented for animating gaze shifts of virtual characters towards target locations in a virtual environment. Two connected components are described: an eye-head controller and a blinking controller. The gaze control model is based ...
Eye, Head and Torso Coordination During Gaze Shifts in Virtual Reality

Humans perform gaze shifts naturally through a combination of eye, head and body movements. Although gaze has been long studied as input modality for interaction, this has previously ignored the coordination of the eyes, head and body. This article ...
Vibrotactile stimulation of the head enables faster gaze gestures

Gaze gestures are a promising input technology for wearable devices especially in the smart glasses form factor because gaze gesturing is unobtrusive and leaves the hands free for other tasks. We were interested in how gaze gestures can be enhanced with ...
