Body-Prop Interaction: Evaluation of Augmented Open Discs and Egocentric Body-Based Interaction

摘要

This paper presents a novel interaction technique to combine multiple inputs and output modalities with a 3D printed open disc which is tracked and augmented with a virtual information. Props have been used in virtual and augmented environments to provide tangible associations to virtual elements. When used in a larger immersive environment or where a user is walking around, users may not have the capability to set these objects/props down or are limited to the number of hands, so users are reduced to the capability of using only two props or controllers. In our technique, users can instead use their body to store and organize the virtual objects associated with tangible props by physically hanging them on or attaching them to the body. This type of interaction is well-suited for both immersive visualizations and immersive virtual environments. In this paper, we present the results of an experimental evaluation of our Body Prop Interaction technique for each type of immersive environment and corresponding task type, demonstrating more effective usage in each scenario than a joystick or gesture-based interaction.
