Abstract
Official abstract text for this publication.
An optical coordinate input device is disclosed. The optical coordinate input device includes a frame, a first touch detection area, a second touch detection area, a first detection module, a second detection module, and a processing module. The second touch detection area overlap the first touch detection area. The first detection module is disposed on the frame and adjacent to the second touch detection area for detecting the first touch detection area to generate a first touch coordinate signal. The second detection module is disposed on the frame and adjacent to the first touch detection area for detecting the second touch detection area to generate a second touch coordinate signal, wherein the first and second detection module are disposed on different surface of the frame. The processing is used for executing a coordinate calculation procedure base on the first and the second touch coordinate signal.
First claim
Opening claim text (preview).
