TRIUMPH BOARD 89” MULTI Touch is based on IR Cell LED Optical technology which uses a combination of IR LEDs and photo transistors aligned in pairs around the active surface. These pairs of LEDs and photo transistors cast a grid over the surface. When the surface is touched, the infrared light beam between the LEDs and the photo transistors is interrupted at the point of touch. This position is converted into an ‘X’ and a ‘Y’ coordinate that the computer then converts into a mouse position.
