Exploring Gesture Based Interaction with a Layered Stereoscopic 3D Interface

Stereoscopic 3D (S3D) is an emerging trend among visualization and display techniques, and spreading especially in the area of the entertainment industry. Due the emerging phase of the technology, it is not yet known which kinds of interaction design solutions are optimal. In this paper, we investigate different gestures to interact with an S3D interface, by comparing one-handed and two-handed interaction with objects in a 3D puzzle game, where objects had to be manipulated between different depth layers. Additionally, two different interaction modes to change objects' depth level were compared, level toggling and stepped direct manipulation. The results indicate that single-handed gestures using a depth toggling interaction were the preferred and fastest way to interact with the S3D puzzle.
