A portable electronic device (10A) includes a menu display (14) having a plurality of menu items (18A-18C), and a menu item pointer (16) movable by a user to highlight particular menu items. The portable electronic device includes a motion sensor (20) for sensing relative movement between the portable electronic device and an imaging surface (106). The motion sensor is configured to generate a first set of movement data indicating a first relative movement between the portable electronic device and the imaging surface. The motion sensor is configured to generate a second set of movement data indicating a second relative movement between the portable electronic device and the imaging surface. A controller (204) is configured to move the menu item pointer based on the first set of movement data to highlight a first menu item. The controller is configured to select the first menu item based on the second set of movement data. <IMAGE> |
