Perceptual user interface in virtual shopping environment

In this paper we present our effort towards the goal of perceptual user interface for main interaction tasks, such as navigation/travel, selection/picking and personal data access in a virtual shopping environment. A set of 3D navigation devices, vision-based pointing and personal access system are mainly discussed. The motivation and design principles behind these interfaces are also described. A prototype integration solution which brings these devices together in a virtual shopping environment, is given. These interfaces and interaction devices have been implemented and are tested for evaluation.
