Navigation of a virtual environment (VE) can mean navigating a VE that is spatially larger than the available Physical Tracked Space (PTS). Accordingly, the concept of redirected walking was introduced in order to provide a more natural way of navigating a VE, albeit with many restrictions on the shape and size of the physical and virtual spaces.

Accordingly, the inventors have established a novel technique which overcomes these limitations. The technique is based on the psychological phenomenon of inattentional blindness allowing for re-directed walking without requiring the triggering major saccades in the users, complex expensive systems, etc.
