PROXIMITY OBJECT TRACKER
First Claim
Patent Images
1. An electronic system comprising:
- a camera having a field of view of a first area;
an illumination source that is angled with respect to the camera and that is configured to illuminate a second area, the second area intersecting the first area to define an intersection region within the field of view of the camera; and
a processing unit configured to perform operations comprising;
capturing an image from the camera;
analyzing the image captured by the camera to detect an object within the intersection region;
determining user input based on the object detected within the intersection region; and
controlling an application based on the determined user input.

Abstract
Object tracking technology, in which controlling an illumination source is controlled to illuminate while a camera is capturing an image to define an intersection region within the image captured by the camera. The image captured by the camera is analyzed to detect an object within the intersection region. User input is determined based on the object detected within the intersection region and an application is controlled based on the determined user input.

25. At least one computer-readable storage medium encoded with executable instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:
-
capturing an image from a camera; analyzing the image captured by the camera to detect an object within an intersection region defined within the camera'"'"'s field of view by an illumination source; determining user input based on the object detected within the intersection region; and controlling an application based on the determined user input.
