It was mentioned at the top of this chapter that the three areas which it reviews will be related in Chapter 3 to the measurement, manipulation and malformation of selected rest frames. This section surveys the literature relevant to the manipulation of the selected rest frame through foreground occlusions.
There are two aspects to this discussion. The first is the effect of foreground occlusions on presence. The second is whether the effect of foreground occlusions on the selected rest frame can be measured through a spatial performance task (specifically, a roll-correction task associated with inside-out displays).
This section summarizes the literature relevant to the research reported in Chapter 5. It borrows in part from [83].
