interactive touch screen video.Mounted at the top left corner of the CCD camera , through the LED emits light rays , after four weeks reflecting reflection bar , into the upper right corner of CCD camera in . Similarly , the upper right corner of the CCD light emitted camera passed the left CCD camera head . The dense light forms a light net in the touch area, and the space between the light that has been reflected multiple times is within 1MM . When you touch a point, the emitted light and the received light at that point form an included angle. At the same time, the CCD camera at both ends and the two lines and the straight line formed between the two cameras will form two included angles, so that the point is accurate. Coordinates are entered by the controller to achieve touch response. When using multi-touch, the principle is the same !
