A 10 point touchscreen can register 10 distinct points of contact all at once. Not all touchscreen devices and displays utilise this technology. But, having it makes a huge difference in the accuracy of your taps, swipes, and various gestures. With one or two-point touchscreens, any accidental contact like the edge of your palm grazing the screen could confuse the interface and register a tap where it shouldn’t be. Utilising a 10 point touchscreen largely eliminates that kind of accidental interaction. And, it also allows for more complex interactions like typing directly on the screen.
