Title: Innovations of John Andrew in Touch-Sensitive Display Technology

Introduction

John Andrew is an accomplished inventor based in Cambridgeshire, GB. He has made significant contributions to the field of touch-sensitive display devices, holding two patents that showcase his innovative approach to technology.

Latest Patents

His latest patents include advanced touch-sensitive display devices. The first patent describes a touch-sensitive image display device that incorporates an image projector to project a displayed image onto a surface. It features a touch sensor light source that projects a plane of light above the displayed image, along with a camera that captures a touch sense image from light scattered by an approaching object. The signal processor processes this touch sense image to identify the location of the object. Notably, the touch sensor light source is amplitude modulated, and the signal processor is designed to compensate for ambient light in touch sense images.

The second patent outlines a touch-sensitive device that includes a touch sensor light source projecting a plane of light above a surface. This device utilizes a camera to capture a touch sense image from a region that includes the plane of light. The signal processor processes the touch sense image to identify the lateral location of multiple objects simultaneously approaching or touching the surface. The processor is configured to input a succession of touch sense images, filter candidate object touch positions, and update previously identified output object positions.
