I need to outline these problems.
People always search for meaning in an unfamiliar space.
They create their own metaphors to understand their environment. There needs to be a datum, or some frame of reference which follows the participant around to create a sense of presence and aid in orientation. Orientation can be aided by adding lots of tools in the environment for the participant's use, or it may be solved spatially. This may lead to a spatial address system which may be limited to three search variables. Up implies value, hierarchy, and relativity.
