Abstract:The contribution of indoor wireless technology to solve the indoor wayfinding problem is potentially big. However, no structured way of describing indoor environments exists today. Also indoor wireless positioning technologies are just emerging and there is not yet a dominant technology. In this thesis a structure to functionally describe indoor environments is developed. Elements of indoor environments are identified. Using these functional elements it is possible to describe a position at four different layers of abstraction, ranging from local view to a rough view of the environment, based on the main functions. After experimental results indoor GPS is ruled out as wireless indoor positioning technology. Experiments with WLAN show that this technology is able to provide high accuracy at a low cost. This technology combined with the developed structure opens up possibilities for various applications, particularly in the area of indoor wayfinding and navigation systems. Especially the possibility to functionally describe the indoor environment at different layers of granularity will improve the spatial awareness of users.
