In our modern world, touchscreens are a common sight. According to a Pew Research survey conducted in November 2016, 77% of Americans own a smartphone and 51% own a tablet computer. While the touchscreen has been around for decades, it's never seen popularity like this. But where did they come from? How did they become so widespread? And how can we expect them to change? When compared to other computer devices, touchscreens are unique because they handle both input and output — interpreting the user's actions while featuring a graphic display. They allow the user to interact directly with what's on the screen, unlike a mouse that moves a cursor. Theoretically, this is a faster design because the pointer doesn't need to travel across the screen between different objects. Touchscreens can additionally come with a number of features that increase their functionality. Multi-touch – the screen can detect the presence of more than one points of contact for input. A "10-point" touchscreen will distinguish all ten of a person's fingers separately. Pressure sensitivity – the amount of pressure applied to the screen is also detected. This adds another layer of input and is used in the Apple Watch as Force Touch and 3D Touch in the iPhone 6S. Gesture recognition – the touchscreen recognizes certain finger motions as separate commands, such as double-tapping to select text or pinching to zoom out. Haptics – recreates the sense of touch with motion. In today's smartphones, it often refers to vibration generated when touching the screen. Fingerprint resistance – since most users will be using their fingers, newer screens are have oleophobic coating (Greek for "fear of oil") that prevents oils from sticking to the surface.
