The TSItouch Infrared (IR) based solution allows for a high accuracy interactive experience. Infrared touch screens operate on the basis of light-beam interruption, commonly referred to as beam break, to determine the location of touch events. Infrared uses an array of X-Y infrared LED and photo detector pairs around the edges of the screen to detect a disruption in the pattern of LED beams. These LED beams cross each other in vertical and horizontal patterns.

As an object touches the screen, it interrupts the light-beam causing a loss of light at the sensor. This loss of light is used to determine the location of the touch event, helping the sensors pick up the exact location of the touch. A major benefit of such a system is that it can detect essentially any input including a finger, gloved finger, stylus, or pen. Available in sizes up to 500"
