User interface controller method and apparatus for a handheld electronic device
First Claim
1. A user interface controller of a handheld electronic device, comprising:
- a display, a camera that generates video images; and
a processing function coupled to the display and the camera, that presents information on the display, processes the video images to generate a three dimensional track of a position of a directing object that is within a field of view of the camera, generates a two dimensional position of the directing object that is used to control a corresponding location within a scene on the display, and controls a function of the handheld electronic device in response to a comparison of the track of the directing object to a virtual surface that is defined relative to the handheld electronic device.

Abstract
A user interface controller of a handheld electronic device (100) that has a camera that generates video images presents (1005) information on a display (105) of the handheld electronic device, processes (1010) the video images to track a three dimensional position of a directing object (260) that is within a field of view (225) of the camera, generates (1015) a two dimensional position of the directing object that is used to control a corresponding location in a scene on the display, and controls (1020) a function of the handheld electronic device in response to a comparison of the track of the directing device to a virtual surface (805, 810, 920, 925) that is defined relative to the handheld electronic device.
