How do users select stereoscopic 3D content?

A large number of research has looked into the three dimensional (3D) related technology especially in 3D content capture, production, compression, and delivery. However, few research has addressed the design practice of interaction techniques for stereoscopic 3D video interaction. This paper presents a study of object selection in 3D from users´ perspective. The aim is to learn the user preferences and user behaviour of selecting stereoscopic 3D content. The study suggests that interaction techniques affects users´ decision of object selection in terms of chosen location in 3D, while user attitudes do not have significant impact. Furthermore, the ray-casting based interaction using Wiimote can outper-form the volume-based interaction technique using the mouse and keyboard for object selection accuracy.
