Optical gesture sensor using a single illumination source |
摘要 |
A gesture sensing device includes a single light source and a multiple segmented single photo sensor, or an array of photo sensors, collectively referred to herein as segmented photo sensors. A light modifying structure relays reflected light from the light source onto different segments of the segmented photo sensors. The light modifying structure can be an optical lens structure or a mechanical structure. The different segments of the photo sensor sense reflected light and output corresponding sensed voltage signals. A control circuit receives and processes the sensed voltage signals to determine target motion relative to the segmented photo sensor. |
