Camera-based Interactive Touch Screen is a touch detection technique that uses a camera to provide a large display with very high spatial and temporal resolutions. The conventional touch screen technology and presentation methods face a range of restrictions. However, the camera-based touch detection can overcome all these restrictions and turn projection screens into interactive touch displays, creating a through-window experience. It uses a coated sheet of glass as the projection surface to form a two-dimensional display. The camera captures images of the projection surface continuously, which are processed by the Atmega16 microcontroller. A UART module connected to the microcontroller, provides asynchronous serial communication with external devices, synchronisation of the serial data stream and recovery of data characters. This technology has several advantages over other touch detection technologies, such as its low cost, simple design and scalable structure. The applications of this technology include advertising, presentations and outdoor displays.
