Visualizing Off-Screen Locations

When a map is displayed on a PDA or smartphone, it is rarely possible to be zoomed in close enough to view detailed information and view all locations of interest (for example, nearby restaurants) around a certain area. We are investigating a class of visualization techniques that indicate the presence and location of targets that are close to the displayed area, while providing a mechanism to interact directly with the off-screen targets.

I designed two new techniques to visualize off-screen points of interest, EdgeRadar and Wedge. These techniques address the problem of clutter that limits the effectiveness of traditional techniques and with Wedge improves upon the user's ability to pinpoint the exact position of unseen objects.
