Augmented reality with large 3D models on a PDA

Abstract

We have implemented a client/server system for running augmented reality applications on a PDA device. The system incorporates various data compression methods to make it run as fast as possible on a wide range of communication networks, from mobile phone links to WLAN, We provide a detailed description of various implementation issues, data compression optimisations, and performance analysis of the system, Usability of the system is evaluated in a demanding architectural application, with a large virtual building rendered in an outdoors location.
