Virtual rehabilitation often incorporates an element of travel in a virtual environment. Whether
patients are transported automatically through the environment, or whether they have navigational
control, it is important to understand how the design of the environment itself can supply
navigational cues, and how the processing of these cues may influence perception, behaviour and
task performance. This paper explores the literature, which might inform application design, and
presents a case study using a think-aloud protocol to explore the perception of users to visual cues
within a running game. We conclude with some preliminary suggestions for positive and negative
navigational cues.
