This project investigates an effective means of streaming and displaying complex 3D scenes over a low-bandwidth wireless network to a remote PDA device, which has limited graphical capabilities. The PDA is also made position-aware, allowing user interaction to occur with a new degree of freedom, mapping real world movements such as rotation to virtual environment changes. Rendering techniques such as silhouetting optimise PDA display rate, but slow PDA processing speed means image compression to reduce network latency is unfeasible. In spite of any technical limitations, however, preliminary user testing shows that the concept and methods of interaction developed are intuitive, with good potential for further system development.
