Multi-touch (or multitouch) denotes a set of interaction techniques which allow computer users to control graphical applications with several fingers.
Multi-touch consists of a touch screen (screen, table, wall, etc.) or touchpad, as well as software that recognizes multiple simultaneous touch points, as opposed to the standard touchscreen (e.g. computer touchpad, ATM), which recognizes only one touch point. This effect is achieved through a variety of means, including but not limited to: heat, finger pressure, high capture rate cameras, infrared light, optic capture, tuned electromagnetic induction, ultrasonic receivers, transducer microphones, laser rangefinders, and shadow capture[1].
Many applications for multi-touch interfaces exist and are being proposed. Multi-touch is often associated with Apple Inc's iPhone and iPod Touch but is also used in many other products such as Apple's MacBook and MacBook Pro notebook line. Other products with multi-touch technology include Microsoft Surface, Asus EEE PC, and Meizu M8.
Modern multi touch controllers support Single-Touch and Multi-Touch All-Point touchscreen applications which allow functions such as playing video games on a mobile handset,using GPS to key in multiple locations, etc.
