OPTICAL RECOGNITION USER INPUT DEVICE AND METHOD OF RECOGNIZING INPUT FROM USER |
摘要 |
<p>Disclosed is an optical recognition user input device and method for recognizing user input that can prevent an error in recognition of plural touch points. A plurality of optical transmission/reception modules (T/R) are disposed around a touch panel including a plurality of pixels. Each of the optical T/R modules includes a light emitting unit and a light receiving unit. A controller controls operation of the optical T/R modules and calculates a user touch location on the touch panel based on an optical signal received by the light receiving unit.</p> |
