Towards robust and efficient visibility-aware sensor-based mobile spatial interaction

The emerging platforms for viewer-centric mobile spatial interaction are based on best effort performance of the underlying positioning and orientation sensors. Besides, these platforms adopt rather simplified visibility models of the scene geometry, which makes these platforms inadequate for interaction scenarios that demand accurate and visibility-aware interaction. In this paper, we present iView; a client-server reference architecture for mobile spatial interaction that supports both robustness against sensor errors and efficient visibility computing that respects the conventional power and computational limitations of mobile devices.
