While navigation systems for cars are in widespread use, only recently, indoor navigation systems based on smartphone apps became technically feasible. Hence tools in order to plan and evaluate particular designs of information provision are needed. Since tests in real infrastructures are costly and environmental conditions cannot be held constant, one must resort to virtual infrastructures.
In this paper we present a hands-free navigation in such virtual worlds using the Microsoft Kinect in our four-sided Definitely Affordable Virtual Environment (DAVE). We designed and implemented navigation controls using the user's gestures and postures as the input to the controls. The installation of expensive and bulky hardware like treadmills is avoided while still giving the user a good impression of the distance she has travelled in virtual space. An advantage in comparison to approaches using head mounted augmented reality is that the DAVE allows the users to interact with their smartphone. Thus the effects of different indoor navigation systems can be evaluated already in the planning phase using the resulting system.
