Facilitating interaction with stereoscopic 3D display devices

In spite of a large body of research focused on 3D video technology, very little attention has been dedicated to the design practices of stereoscopic 3D video interaction devices. Interaction tasks such as pointing and selection are critical to the consumer´s experience of the 3D video technology. This paper presents implementation and investigation of pointing modalities in the context of stereoscopic 3D display devices. The conducted investigation implements three pointing modalities: standard mouse-based interaction, virtual laser pointer implemented using Wiimote, and hand movement modality using Kinect. The study explores it´s utilisation in interactive tasks such as two-handed interaction and zoom functionalities. Finally, we investigate the definition of interaction space for hand movement modality to facilitate effective and comfortable pointing.
