A painting application will normally allow many fingers/inputs to draw simultaneously.

For instance, in Mac OS x, doing a 4 finger swipe on the screen will switch the screen to different full screen spaces etc. The Mac OS x and Windows operating systems also have built in gestures for using two or more fingers when performing a task. However, if you’re using an application that requires you to “Orbit” around an item in 3D space, this is traditionally done by 3 fingers instead of two. Most applications only need 2 touch points for standard pinch, zoom, and rotate functions. It is important depending on the software you will be using to operate your touch system. Why is the amount of touch points important? The amount of touch points an overlay has represents how many simultaneous fingers, on the screen, can be recognized by the touch overlay. What does 2 touch points, 6 touch points, 12 touch points, or 32 touch points mean? The unique and patented design utilizes independent LPUs (Light Processing Units) and optimized touch point detection algorithms, Cell Imaging Technology, to provide stable and superb touch performance. When an object touches the screen, the invisible light beam is interrupted, causing a drop in the signal received by the photo sensors.

The frame has light sources, or light emitting diodes (LEDs) on one side and light detectors on the opposite side, creating an optical grid across the screen. Instead of an overlay on the surface, a frame surrounds the display.

Infrared touch screens are based on light-beam interruption technology. We use a product that is based on IR touch technology. All 2 or more touches are detected and fully resolved resulting in a dramatically improved touch experience What type of touch technology do you use?
