Force Touch -- which senses how hard the screen is tapped -- was first used in the Apple Watch and 12-inch Retina MacBook. For example, with the Watch, pressing firmly on the screen lets you select new watch faces, control a workout, or search an address in Maps. Apple claims Force Touch “is the most significant new sensing capability since Multi‑Touch” – the tap, scroll, pinch, and swipe gestures found on MacBooks.
