ABSTRACT
As indoor wayfinding can be very challenging, adapted systems, which adapt the route instruction type, are being developed to facilitate more supportive indoor route guidance. In this study, such a system has been developed based on the results of an online survey. This adapted system was compared with a non-adapted system by use of eye tracking, position tracking, an orientation test and a questionnaire. The results revealed that using symbols instead of photos reduced the imposed cognitive load, while using 3D-simulations instead of photos improved the environmental awareness. This resulted in less wayfinding errors with the adapted system, compared to the non-adapted system. Therefore, the present study provides additional evidence on the benefits of adapted systems for indoor route guidance.
