The NEC Touch Overlay Accessories allow for multi-touch functionality on large NEC displays through an IR touch technology that supports up to 10 simultaneous touches. The overlays have a superior design with a swipe zone that enables Windows 8 compatibility and a steel chassis with tempered glass for safety. Installation of the overlays is easy through a simple 3-step process of removing screws, attaching the overlay, and replacing screws, making integration fast.
