The present starburst target expansion technique connects targets to peripheral screen space to produce reasonably sized tiles for all targets including those that are located inside of a cluster. The resulting layout is characterized by lines escaping from the cluster center. By providing targets located inside a cluster with access to empty screen space, the present starburst target expansion technique is able to assign screen space to targets that remain small if expanded using the traditional Voronoi approach. If used on a device with limited input accuracy, such as a pen-based tablet or a touch screen-based kiosk system, target expansion via the starburst target expansion technique can lead to substantial performance improvements.
