Multi-Touch technology works with touch-screen and TrackPad interfaces. Both of these surfaces are able to measure and respond to pressure through the use of a pressure-sensitive panel carrying an electrical charge. Where a pressure is applied, the electrical charge is disrupted, which is read by the computer as an input. This input is then translated to a corresponding motion or function by the device's software. Multi-Touch technology allows these panels to read and interpret multiple pressure points, including gestures, at the same time.
