  • Spatial Detection on an Electronic Device Using Optical Coding
    Publication number: 20110303832
    Abstract: A method of detecting motion at an electronics device includes a detector at the device. Light reflects from an object located external to the device and is projected onto a mask. The mask includes a predetermined pattern of light-transmissive and opaque areas that will either allow, or block the reflected light from passing through the mask and forming a light pattern on the light-sensitive surface of a light sensor. The light sensor generates a waveform based on this light-pattern, and a processor processes the generated waveform to detect whether the object is in motion.
