Two-handed interaction on a tablet display

A touchscreen can be overlaid on a tablet computer to support asymmetric two-handed interaction in which the non-preferred hand operates the touchscreen and the preferred hand uses a stylus. The result is a portable device that allows both hands to interact directly with the display, easily constructed from commonly available hardware. The method for tracking the independent motions of both hands is described. A wide variety of existing two-handed interaction techniques can be used on this platform, as well as some new ones that exploit the reconfigurability of touchscreen interfaces. Informal tests show that, when the non-preferred hand performs simple actions, users find direct manipulation on the display with both hands to be comfortable, natural, and efficient.
