For example, the World-in-Miniature (WIM) technique (Stoakley et al., 1995), which allows users to move virtual objects in a full-scale virtual environment by manipulating small "dollhouse" representations of those objects, was originally designed for an HMD with two handheld trackers for input. When we tried to migrate WIM to a CAVE (Bowman et al., 2007), we found performance to be significantly worse, probably because users found it difficult to fuse the stereo imagery when the virtual WIM was held close to their eyes. In addition, we had to add controls for rotating the world due to the missing back wall of the CAVE. More recently, we tried to migrate WIM to use the Kinect, and were not able to find any reasonable mapping that allowed users to easily manipulate both the WIM and the virtual hand with six DOFs.
