Input method for surface of interactive display
First Claim
1. A method for detecting an object or user input provided with an object using a scanning light source, comprising the steps of:
- illuminating an interactive display surface with at least one scanning light source, wherein the interactive display surface has an external surface and an internal surface, wherein the at least one scanning light source is configured to emit light of a predetermined wavelength and scan interactive display surface with the light of the predetermined wavelength, so that the entire interactive display surface is fully scanned over time, and wherein illuminating the interactive display surface includes the at least one scanning light source emitting the light through a photosensitive light surface toward the interactive display surface; and
detecting light of the predetermined wavelength that is reflected from an object that is on or proximate the external surface of the interactive display surface, the light that is reflected being detected as the at least one scanning light source is illuminating the object with the light of the predetermined wavelength, and wherein the photosensitive light surface acts as a detector for the predetermined wavelength reflected from the object.

Abstract
An interactive display system configured for detecting an object or user input provided with an object. The system includes a display surface on which graphic images are displayed, one or more scanning light sources configured for scanning the interactive display surface, and a light detector configured for detecting light reflected from an object that is adjacent to or in contact with the interactive display surface. A computing system storing machine instructions is in communication with the scanning light source and the light detector. When executed, the machine instructions cause the computing system to illuminate the interactive display surface with the scanning light source, to detect light with the light detector that is reflected from an object after illumination with the light source, and to generate an output signal based on the detected light that has been reflected from an object on or adjacent to the interactive display surface.
