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. Current designs of offscreen cues can result in overlaps that can make it difficult to use the cues as handles through which users can select the off-screen objects they represent. In this paper, 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 then partitions the border regions to allow for non-overlapping areas that make selection of objects easier. We present an effective algorithm that provides such partitioning and demonstrate the effectiveness of EdgeSplit for selecting off-screen objects.
