TRACKING APPROACHING OR HOVERING OBJECTS FOR USER-INTERFACES
First Claim
1. A system that utilizes photo-sensors to track objects that approach or hover over a UI display, comprising:
- a UI display that includes a set of photo-sensors that detect electromagnetic radiation;
a light analysis component that identifies a coordinate on the UI display based upon data received from the set of photo-sensors, the coordinate relates to a position of a selector object; and
a tracking component that monitors the position of the selector object relative to the UI display.

Abstract
The claimed subject matter relates to an architecture that can utilize photo-sensors embedded in a substantially transparent layer of a UI display for tracking objects that approach or hover over the UI display. The photo-sensors can be configured to detect light of certain wavelengths (e.g., visible light, infrared light) that are propagated toward the UI display, while ignoring light emanating from the UI display when displaying content. Accordingly, by examining various characteristics of the incoming light such as intensity, the architecture can identify a location of a shadow incident upon the display caused by an approaching or hovering selector object blocking portions of incoming light. Additionally or alternatively, the architecture can identify a location of higher intensity for light emanating from the selector object.

17. A method for employing photo-sensors for tracking approaching or hovering objects with respect to a UI display, comprising:
-
including in a UI display an array of photo-sensors that compose one or more layers of the UI display; employing data from the array of photo-sensors for selecting a coordinate on the UI display that is associated with a position of a selector object; and tracking the position of the selector object relative to the UI display. - View Dependent Claims (18, 19)

20. A system that utilizes photo-sensors to track objects that approach or hover over a UI display, comprising:
-
a touch-sensitive UI display that includes an array of photo-sensors distributed among one or more layers of the UI display, each of the photo-sensors included in the array is configured to detect an intensity of electromagnetic radiation with a wavelength in the range of about 300 nanometers to about 1 millimeter; a light analysis component that identifies a coordinate on the UI display based upon data received from the set of photo-sensors, the coordinate relates to a location of a shadow cast by a selector object or an intersection of infrared radiation propagated from the selector object; and a tracking component that monitors the position of the selector object relative to the UI display.
