20100277436 | Sensing System for a Touch Sensitive Device - A sensing system for sensing a touch input on a touch sensitive device, the system including: a sensing plane; a well-collimated light source for generating a plurality of light rays along one or more planes different from the sensing plane; and a reflecting means adjacent one edge of the sensing plane for transforming at least a subset of the light rays into substantially parallel light rays and redirecting the subset of light rays along the sensing plane, at least one of the light rays along the sensing plane being interruptable by the touch input thereby allowing the sensing system to determine a position coordinate of the touch input. A related method of sensing a touch input on a touch sensitive device is also provided. | 11-04-2010 |
20100289755 | Touch-Sensing Liquid Crystal Display - Disclosed are systems, methods and techniques to integrate touch-sensing functionality with a liquid crystal display (LCD) panel. In a particular implementation, light sensing detectors are disposed on a backlight panel to detect changes in light incident on the backlight panel in response to a physical touching on a surface of an LCD panel. A location of the physical touching may then be estimated based upon signals received from the light sensing detectors. | 11-18-2010 |
20110241986 | INTERACTIVE PROJECTION DEVICE - The subject invention relates to an interactive projection device. The interactive projection device includes a light source configured to emit an input light beam, wherein the light source comprises a visible light emitting device; a first beam splitter configured to split the input light beam into first and second split light beams; a second beam splitter configured to split a scattered light beam received from a surface into third and fourth split light beams; an image forming device configured to produce an image light beam based on the first split light beam and emit the image light beam onto the surface through the first and second splitters, thereby generating a projection image on the surface; and a detector configured to detect the invisible light of the third split light beam, thereby acquiring a scattering image from the surface. | 10-06-2011 |
