Abstract:
1. An optical coordinate input device, comprising: a frame; a first touch detection area; a second touch detection area, overlapping part of the first touch detection area, wherein the first touch detection area and the second touch detection area are provided for a user touching; a first detection module, disposed on the frame and adjacent to the second touch detection area for detecting the first touch detection area and generating a first touch coordinate signal when the user touches the first touch detection area; a second detection module, disposed on the frame and adjacent to the first touch detection area for detecting the second touch detection area and generating a second touch coordinate signal when the user touches the second touch detection area; wherein the first detection module and the second detection module are located on different surfaces of the frame; and a processing module, electrically connected to the first detection module and the second detection module, provided for executing a coordinate calculation procedure according to the first touch coordinate signal and the second touch coordinate signal so as to operate the first touch detection area and the second touch detection area simultaneously.
