Navigating in complex indoor environments such as hospitals, can be a complicated task. In addition to losing one's way, lack of sufficient wayfinding information is also known to cause both psychological and physiological strain. All of these issues can cause delays and extra work for hospital staff, consequently leading to financial losses for the institution. Over the course of three experiments of limited sample sizes (6, 15, 10), we have developed an RFID enabled multimodal wayfinding system based on procedural generation of 2D and 3D route visualizations and fitted wayfinding information. In a comparative study conducted in situ at Aalborg University Hospital South, we determine that the egocentric 3D route visualization and dynamic allocentric map activated through RFID detection leads to improved wayfinding performance in metrics such as completion time, hesitations, and route length compared to the in-place navigation system (signs, colored floor lines, etc.). We see the potential in a more comprehensive implementation, due to the clear indications of wayfinding improvements, and the benefits that these afford for both institutions and wayfinders.
