User awareness of tracking uncertainties in AR navigation scenarios (Poster).
Proceedings of the 12th International Symposium on Mixed and Augmented Reality (ISMAR), Oct. 1-4 2013, pp. 285-286. (bib)

Current Augmented Reality navigation applications for pedestrians usually do not visualize tracking errors. However, tracking uncertainties can accumulate so that the user is presented with a distorted impression of navigation accuracy. To increase the awareness of users about potential imperfections of the tracking at a given time, we alter the visualization of the navigation system. We developed four visualization and error visualization concepts and used a controlled Mixed Reality environment to conduct a pilot study. We found that, while error visualization has the potential to improve AR navigation systems, it is difficult to find suitable visualizations, which are correctly understood among the users.
