The Right Data at the Right Moment for the Right Person — User Requirements and Their Implications for the Design of Indoor Navigation Systems

Indoor Navigation Systems are constantly improved in a variety of technological fields, but often without considering individual user requirements. As a direct consequence, navigation information is not sufficient for the variety of all users. By combining and evaluating user requirements and data models for indoor representation, five categories of indoor navigation information were compiled. OpenStreetMap (OSM) serves as a basis to form items for an online survey for able-bodied, visually and motorically impaired people. Based on the results, we determined: User groups are an important element in indoor navigation. Individual preferences and time dependence of information need to be considered additionally. These results are then used to derive implications for several stages and components in the technological development process. We argue that following these implications by including user requirements in these processes will lead to a higher satisfaction with Indoor Navigation Systems for all users.
