GRID is a technology which enables tracking of multiple devices on standard LC-displays. This technology uses the fact that the LC-matrix of an LC-display is mostly transparent to infrared light. By using active infrared interaction devices it becomes possible to radiate through the LC-matrix and detect the radiation behind the screen. Detection of the infrared light is done by using an array of infrared sensors. In order to distinguish between different devices a synchronization technique makes sure all the devices are interrogated in different timeslots.
