Positioning

In VR games which use an avatar (a puppet to represent the viewer), it is sometimes necessary to reposition the avatar slightly. This prevents it reaching positions from which it is difficult to make further progress.

Here is an example of that in action, in this case with no physical obstruction. Lara Croft is standing on a slope. With no user intervention she slowly slides down to level ground. The two shots show the "before" and "after" views of this happening.
