SELF-REFERENCED TRACKING

摘要

A new tracking technique is essentially "sourceless" (30) in that it can be used anywhere with no set-up, yet it enables a much wider range of virtual environment-style navigation and interaction techniques than does a simple head-orientation tracker. A sourceless head orientation tracker (30) is combined with a head-worn tracking device (120) that tracks a hand-mounted 3D beacon (14) relative to the head (16). The system encourages use of intuitive interaction techniques which exploit proprioception.
