EdgeSplit: Facilitating the Selection of Off-Screen Objects



Devices with small viewports (e.g., smartphones or GPS) result in interfaces where objects of interest can easily reside outside the view, into off-screen space. Researchers have addressed this challenge and have proposed visual cues to assist users in perceptually locating off-screen objects. However, little attention has been placed on methods for directly selecting these objects.

We present EdgeSplit, a technique that facilitates both the visualization and selection of off-screen objects on small devices. EdgeSplit exploits the space around the device's borders to display proxies of off-screen objects and partitions the border regions to allow for non-overlapping areas that make selection of objects easier.
