Abstract

Wearable augmented reality (AR) can help the task of auser by adding virtual objects to his view on the realworld. To save power in the mobile unit, rendering can beoffloaded to the backbone as much as possible. However,because of low latency requirements, images for mobileAR can not be rendered completely in the backbone. Wedeveloped a system capable of end-to-end latencies of10ms, with a seamless fitting dynamic level-of-detailframework extending the VRML and Inventor language,and building on current trends in QoS handling. In thispaper we outline the structure and components of oursystem, and discuss a demo application projecting a statueon the campus.
