Abstract

A method performed by a device having a touch panel includes detecting a location of a primary touch on the device and detecting on the touch panel a set of near-touch coordinates associated with the primary touch. The method also includes identifying the approach orientation of the primary touch as one of a left-side touch or a right-side touch based on the location of the primary touch and the near-touch coordinates. The method further includes generating a command signal based on the location of the primary touch and the approach orientation of the primary touch and performing an action based on the command signal.
