Interacting with 3D Content on Stereoscopic Displays

Along with the number of pervasive displays in urban environments, recent advances in technology allow to display three-dimensional (3D) content on these displays. However, current input techniques for pervasive displays usually focus on interaction with two-dimensional (2D) data. To enable interaction with 3D content on pervasive displays, we need to adapt existing and create novel interaction techniques. In this paper we investigate remote interaction with 3D content on pervasive displays. We introduce and evaluate four 3D travel techniques that rely on well established interaction metaphors and either use a mobile device or depth tracking as spatial input. Our study on a large-scale stereoscopic display shows that the physical travel techniques (whole-body gestures) outperformed the virtual (mobile touch) techniques with respect to task performance time and error rate.
