Finger touching a multi-touch screen. In computing, multi-touch is technology that enables a surface (a trackpad or touchscreen) to recognize the presence of more than one or more than two points of contact with the surface.hen a finger touches the screen, the touch disrupts the panel's electrical field. The disruption is registered as an computer event (gesture) and may be sent to the software, which may then initiates a response to the gesture event. In the past few years, several companies have released products that use multi-touch.
