Abstract
A motion controlled handheld device includes a display having a viewable surface and operable to generate a current image. The device includes a motion detection module operable to detect motion of the device within three dimensions and to identify components of the motion in relation to the viewable surface. The device also includes a gesture database comprising a plurality of gestures, each gesture defined by a motion of the device with respect to a first position of the device. The gestures comprise at least four planar gestures each defined by a motion vector generally aligned in parallel with the viewable surface. The device includes a gesture mapping database mapping each of the gestures to a corresponding command, the gesture mapping database mapping each of the four planar gestures to a corresponding grid navigation command. The device also includes a motion response module operable to identify a matching one of the planar gestures based on the motion and to determine the corresponding one of the grid navigation commands based on the identified planar gesture and a display control module operable to logically parse a viewable image into a plurality of grid sections, to set …
