Tool support for building graph construction

Landmark-based navigation is one promising approach among the group of indoor navigation solutions. Using logical connections between areas in the building, users are able to follow a path via step-by-step instructions. This approach provides universally applicable navigation to complex buildings. However landmark-based indoor navigation requires a solid and reliable data structure which depicts regarded buildings. In this paper we present a tool for construction of such data structure. Using findings from prior experiments and well-established design principles and patterns, we were able to significantly improve the usability of the tool and lower the cognitive load of the user. Furthermore, the proposed improvements were integrated into landmark-based indoor navigation software to enhance the user experience and display a more familiar presentation during the navigation task.
