Haptic Feedback

What Haptic Feedback Does on Your Phone

Tap a key on an on-screen keyboard and you may feel a tiny pulse. Press and hold an icon and the phone may answer with a firmer bump. A call can produce a repeating vibration strong enough to notice in a pocket. These sensations are all examples of haptic feedback: physical feedback produced by the device for your sense of touch. Haptics can make a touchscreen feel more responsive even though the glass itself does not move like a mechanical button. They can also communicate events without relying entirely on sound or sight.
