Portable electronic device with mouse-like capabilities
First Claim
1. A method of controlling menu item selection in a portable electronic device, the portable electronic device including a menu display having a plurality of menu items and a menu item pointer movable by a user to highlight particular menu items, the method comprising:
- sensing two-dimensional relative movement between the portable electronic device and an imaging surface with a motion detection device;
generating a first set of movement data with the motion detection device indicating an amount and direction of a first relative movement between the portable electronic device and the imaging surface;
moving the menu item pointer based on the first set of movement data to highlight a first menu item;
generating a second set of movement data with the motion detection device indicating an amount and direction of a second relative movement between the portable electronic device and the imaging surface; and
selecting the first menu item based on the second set of movement data.

Abstract
A portable electronic device includes a menu display having a plurality of menu items, and a menu item pointer movable by a user to highlight particular menu items. The portable electronic device includes a motion sensor for sensing relative movement between the portable electronic device and an imaging surface. 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 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.
