Latest Patents

One of Gillsjö's latest patents is centered around stylus identification. This invention involves an optical infrared (IR) touch sensing apparatus that determines, based on output signals from light detectors, a light energy value for each light path across a touch surface. The apparatus generates a transmission value for each light path based on the light energy value. A processor is configured to operate an image reconstruction algorithm on the generated transmission values to determine the position of a touching object on the touch surface. Additionally, it calculates an attenuation value corresponding to the light's attenuation caused by the object touching the surface. Using these values, the processor can identify the type of object interacting with the touch surface.
