Many tasks in graphical user interfaces require users to interact with elements at various levels of precision. The authors present FingerGlass, a bimanual technique designed to improve the precision of graphical tasks on multitouch screens. It enables users to quickly navigate to different locations and across multiple scales of a scene using a single hand. The other hand can simultaneously interact with objects in the scene. Unlike traditional pan-zoom interfaces, FingerGlass retains contextual information during the interaction.
