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.
Many applications for multi-touch interfaces exist and are being proposed. Some uses are individualistic (e.g., Microsoft Surface, Apple iPhone, Apple iPod touch, Asus EEE PC, Apple MacBook Pro, Apple MacBook Air, HTC Diamond, Meizu M8 ) . However, multi-touch technology is mainly used to incorporate collaboration into the computing experience.
