Abstract:
1. A motion controlled handheld device comprising: a display having a viewable surface and operable to generate a current image; 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 components comprising a first component parallel to the viewable surface, a second component parallel to the viewable surface and perpendicular to the first component, and a third component perpendicular to the viewable surface; a display control module operable to display a cursor on the viewable surface, to determine a translation vector that is substantially opposite to the sum of the first component and the second component, and to translate the cursor across the viewable surface according to the translation vector in order to substantially maintain the position of the cursor in space with respect to the viewable surface; 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; a gesture mapping database mapping each of the gestures to a corresponding command; a motion response module operable to identify a matching one of the gestures based on the motion and to determine a corresponding one of the commands based on the identified gesture; and wherein the display control module is further operable to logically parse a viewable image into a plurality of grid sections, to set one of the grid sections as the current image, and to set another one of the grid sections as the current image in response to the determined command.
