Haptics

A category of technology that allows users to "touch" or "feel" virtual things via mechanical simulation.

In phones, haptics are typically implemented as advanced vibration mechanisms that provide physical feedback coordinated with the interface, applications, and/or games.

For example, a phone with haptics might allow a user to "feel" a click each time they scrolled through a menu item, or "feel" the rough edge of the road in a racing game.
