5.5 Experiment on Cognitive Demands

The experiments presented above showed that users are not able to detect an inconsistency if their physical path is bent with a radius of at least 22 m during virtual straightforward movements. If redirected walking is applied in a smaller workspace, manipulations become noticeable, but users are still able to move through a potentially infinitely large virtual world by walking. For this seminatural form of locomotion, the question arises if such manipulations impose cognitive demands on the user, which may compete with other tasks in IVEs for finite cognitive resources. In this section, we present an experiment in which we analyze the mutual influence of redirected walking and verbal as well as spatial working memory tasks using a dual-tasking method.
