1. A motion controlled handheld device comprising:

  • a display having a viewable surface and operable to generate an image;

    a gesture database maintaining a plurality of gestures, each gesture defined by a motion of the device with respect to a first position of the device;

    a motion detection module operable to detect motion of the handheld device within three dimensions and to identify components of the motion in relation to the viewable surface; and

    a control module operable to;

    identify a base reference position of the device;

    track movement of the device, using the motion detection module, to identify a potential gesture;

    compare the potential gesture against the gestures in the gesture database; and

    determine whether the potential gesture matches to a compared one of the gestures based on whether a difference between the potential gesture and the compared gesture is within a precision threshold.
