Abstract

Augmented Reality (AR) systems that employ user-worn display and sensor technology can be problematic for certain applications as the technology might, for instance, be encumbering to the user or limit the deployment options of the system. Spatial AR systems instead use stationary displays that provide augmentation to an on-looking user. They could avoid issues with damage, breakage and wear, while enabling ubiquitous installations in unmanned environments, through protected display and sensing technology. Our contribution is an exploration of compatible interfaces for public AR environments. We investigate interactive technologies, such as touch, gesture and head tracking, which are specifically appropriate for spatial optical see-through displays. A prototype system for a digital museum display was implemented and evaluated. We present the feedback from domain experts, and the results from a qualitative user study of seven interfaces for public spatial optical see-through displays.
