Predator-prey vision metaphor for multi-tasking virtual environments

Narrow field of view of common Head Mount Displays, coupled with lack of adaptive camera accommodation and vergence make it impossible to view virtual scenes using familiar eye-head-body coordination patterns and reflexes. This impediment of natural habits is most noticeable in applications where users are facing multiple tasks, which require frequent switching between viewing modes, from wide range visual search to object examination at close distances. We propose a new technique for proactive control of the virtual camera by utilizing a predator-prey vision metaphor. We describe the technique, the implementation, and preliminary results.
