How Do Touch Screens Actually Work? | iThingum

There are touch screens that use a projected infrared grid. When a finger or other object disrupts the beams then position can be calculated. Optical touch screens work in a similar way, but instead of infrared light they use light from the visible spectrum. Possibly one of the strangest ways of determining touch input is by using sound.
