3D Selection Strategies for Head Tracked and Non-Head Tracked Operation of Spatially Immersive Displays
Anthony J. Steed, Chris Parker · 2004
We present an investigation of selection strategies designed specifically for the spatially immersive display (SID), CAVE TM-like situation. We address two common contexts of use of SID displays: single user head tracked, and two person with one non-head tracked demonstrator and a visitor. This second context is, in our experience, a common use scenario of SIDs, but it, and other issues specific to SIDs, are largely ignored in the literature, which has concentrated on head-mounted displays. We introduce a novel interaction technique, Shadow Cone Selection, which was designed for the situation of non-head tracked interaction. Through analysis and experiment, we show that it might be preferred over standard cone and ray-based selection techniques for some applications.
