Touchless detection display
First Claim
1. A touchless detection display, comprising:
- a transparent display that displays information to a viewer;
a display face through which the viewer views the information;
a light detector that detects incoming light that travels into the touchless detection display through the display face; and
,light control material that receives incoming light that travels into the touchless detection display through the display face before the incoming light reaches the light detector, the light control material preventing portions of the incoming light that are not traveling substantially perpendicular to the display face from reaching the light detector;
wherein locations of objects close to but not touching the display face are detected by the touchless detection display based on the incoming light detected by the light detector.

Abstract
A touchless detection display includes a transparent display, a display face, a light detector and light control material. The transparent display displays information to a viewer. The viewer views the information through the display face. The light detector detects incoming light that travels into the touchless detection display through the display face. The light control material receives incoming light that travels into the touchless detection display through the display face before the incoming light reaches the light detector. The light control material prevents portions of the incoming light that are not traveling substantially perpendicular to the display face from reaching the light detector. Locations of objects close to but not touching the display face are detected by the touchless detection display based on the incoming light detected by the light detector.

11. A method for detecting user input by a touchless detection display, the method comprising:
-
displaying information to a viewer by the touchless detection display; and
,receiving an input selection from the user without the user touching the display, including the following; receiving incoming light that travels into the touchless detection display through the display face and producing louvered light by removing from the incoming light portions of the incoming light that are not traveling substantially perpendicular to the display face, and detecting by the touchless detection display, intensity of the louvered light based on locations at which the louvered light initially entered the display face in order to determine locations of objects close to but not touching the display face. - View Dependent Claims (12, 13, 14)

15. A method for providing a display with the ability to receive touchless input from a user, comprising:
-
placing light control material between a display face and a transparent display that displays information to the user; and placing behind the transparent display a light detector that detects incoming light that travels into the touchless detection display through the display face; wherein the light control material is arranged to receive incoming light that travels into the touchless detection display, the light control material preventing portions of the incoming light that are not traveling substantially perpendicular to the display face from reaching the light detector; and wherein the touchless detection display is enabled to detect locations of objects close to but not touching the display face by the touchless detection display based on the incoming light detected by the light detector. - View Dependent Claims (16, 17, 18, 19)

20. A touchless detection display, comprising:
-
means for displaying information to a viewer; means for detecting incoming light that travels into the touchless detection display through the display face; and
,means for receiving incoming light that travels into the touchless detection display through the display face before the incoming light is detected by the means for detecting incoming light, and for preventing portions of the incoming light that are not traveling substantially perpendicular to a display face of the touchless detection display from being detected by the means for detecting incoming light; wherein locations of objects close to but not touching the display face are detected by the touchless detection display based on the incoming light detected by the means for detecting incoming light.
