Visual Contextual Awareness in Wearable

Small, body-mounted video cameras enable a diierent style of wearable computing interface. As processing power increases, a wearable computer can spend more time observing its user to provide serendipitous information , manage interruptions and tasks, and predict future needs without being directly commanded by the user. This paper introduces an assistant for playing the real-space game Patrol. This assistant tracks the wearer's location and current task through computer vision techniques and without oo-body infrastructure. In addition, this paper continues augmented reality research, started in 1995, for binding virtual data to physical locations.
