Abstract

The integration of sensors in smartphones and tablets is enabling the emergence of augmented reality (AR) applications for these devices. However, the image captured and the superimposed information is limited to the camera's field-of-view and, in the visualization of points of interest (PoI), symbol overlapping may occur because there is no control over their number and location. Thus, we developed an Android prototype application that aims to: provide better environment awareness using clues to off-screen objects and a 2D map with a radar view, reduce symbol overlapping via aggregation visualizations, and guide the attention of the user by featuring different levels of symbol relevance according to user preferences. An empirical study with search tasks revealed participants preferred having all techniques active instead of none or only some of them. This suggests there is value in combining visualization techniques to address mobile AR challenges, and, possibly, that there is still space to integrate more techniques without overloading the users.
