The 40 Point touch foil is the largest standard foil we have available, and provides the best performance for large-scale or demanding projects. With over 4,000 individual sensors and the ability to have 40 simultaneous points of input, the 40 Point foil allows for accurate tracking over wide display distances. This type of foil is typically used on video walls, high-traffic displays, and interactive presentations. If your project is meant to be consistently in use over a very wide surface area, a 40 Point foil is a perfect fit. With 40 points of touch, your display will give up to 20 users the ability to drag, drop, zoom, or right click independently and at the same time.
