Infrared Touch
Infrared Touch is a touchscreen technology that uses infrared light beams to detect touch input on a display surface. It consists of an array of infrared LEDs and photodetectors arranged around the edges of the screen, creating an invisible grid of light. When an object interrupts the beams, the system calculates the touch point based on the blocked coordinates.
Developers should learn about Infrared Touch when working on interactive kiosks, large-format displays, or industrial applications where durability and multi-touch capability are required. It is particularly useful in public spaces due to its resistance to scratches and ability to work with gloved hands or styluses, making it ideal for ATMs, museum exhibits, and outdoor installations.
