Interaction and Rendering Techniques for Handheld

By Finn Ericson and Alex Olwal


We present a number of rendering and interaction techniques that exploit the user's viewpoint for improved realism and immersion in 3D applications on handheld devices. Unlike 3D graphics on stationary screens, graphics on handheld devices are seldom regarded from a fixed perspective. This is particularly true for recent mobile platforms, where it is increasingly popular to use device orientation for interaction. We describe a set of techniques for improved perception of rendered 3D content. View-point correct anamorphosis and stereoscopy are discussed along with ways to approximate the spatial relationship between the user and the device. We present the design and implementation of a prototype phantogram viewer that was used to explore these methods for interaction with real-time photorealistic 3D models on commercially available mobile devices.
