Augmented Reality & Virtual Reality World | 拡張現実と仮想現実の世界

We investigate user experiences when using augmented reality (AR) as a new aid to navigation. We integrate AR with other more common interfaces into a handheld navigation system, and we conduct an exploratory study to see where and how people exploit AR. Based on previous work on augmented photographs, we hypothesize that AR is used more to support wayfinding at static locations when users approach a road intersection. In partial contrast to this hypothesis, our results from a user evaluation hint that users will expect to use the system while walking. Further, our results also show that AR is usually exploited shortly before and after road intersections, suggesting that tracking support will be mostly needed in proximity of road intersections.
