Working principle of optical imaging touch whiteboard

Working together, two optical sensors track the movement of any object close to the surface by detecting the interruption of an infra-red light source. The light is emitted in a plane across the surface of the screen and can be either active (infra-red LED) or passive (special reflective surfaces).

At the heart of the system is a printed circuit controller board that receives signals from the optical sensors. Its software then compensates for optical distortions and triangulates the position of the touching object with extreme accuracy.

By using optical sensors at two corners of the screen, Optical Touch “sees” the touching object from two angles. The result is a high degree of accuracy, with no contact pressure required. No special coatings and films are needed—there is nothing to scratch, wear out, or cloud the display image. The screen can be sealed against dirt, dust, moisture, ideal for heavily used kiosks in public areas.
