Will o’the Wisp: Augmented Reality Navigation for Hikers
In this study we discuss the design of a non-intrusive navigational aid for amateur hikers and evaluate issues of trust and efficiency. We conceptualized an augmented reality interaction to project on-demand GPS directions in front of the hiker, and integrated the system into a hiking stick. We implemented an Arduino-powered prototype to evaluate the concept, interactions, and form factor. Evaluation methods include heuristic evaluations with an expert panel, followed by a round of design iteration. This was proceeded by task-based usability testing with amateur hikers. Our results confirm that hikers adapted easily to the new interaction, though trust in the device was less forthcoming. Data also confirms the efficiency of the projected cues compared to a traditional paper map.
