What is infrared touch frame?
    An infrared touch frame is a device that consists of an array of infrared light-emitting diodes (LEDs) and photodetectors that are mounted around the edges of a touch screen display. When a user touches the screen, their finger interrupts the infrared light beams, and the photodetectors detect the interruption and send a signal to the controller to locate the touchpoint. The controller then sends this information to the computer, which translates it as a mouse click or gesture. Infrared touch frames are widely used in interactive displays, kiosks, and gaming machines due to their durability, accuracy, and low maintenance costs.
