Abstract
The determination of an orientation of a finger touching a touch-sensitive device is disclosed. In one embodiment, a computing device comprises a display screen configured to display an image to a user, and an intensity-sensitive touch-sensing input mechanism configured to detect one or more objects touching the display screen. The device also comprises a controller configured to determine an orientation of a finger touching the screen from a direction between a center of a first set of touch data and a center of a second set of touch data, and to adjust an image on the display screen in response to a determined orientation of the finger.
