Closeup of a touchpad on an Acer CB5-311 laptop Closeup of a touchpad on a MacBook 2015 laptop. A touchpad or trackpad is a type of pointing device.Its largest component is a tactile sensor: an electronic device with a flat surface, that detects the motion and position of a user's fingers, and translates them to 2D motion, to control a pointer in a graphical user interface on a computer screen.
In computing, multi-touch is technology which enables a touchpad or touchscreen to recognize more than one [7] [8] or more than two [9] points of contact with the surface. Apple popularized the term "multi-touch" in 2007 with which it implemented additional functionality, such as pinch to zoom or to activate certain subroutines attached to predefined gestures.

[1] Some touchscreens use ordinary or specially coated gloves to work, while others may only work using a special stylus or pen.
a computer mouse is an indirect, relative, isotonic, position-control, translational input device with two degrees of freedom (x, y position) and two states (tracking, dragging). a touch screen is a direct , absolute , isometric , position-control input device with two or more degrees of freedom (x, y position and optionally pressure) and two ...
The first generation Magic Mouse was released on October 20, 2009, and introduced multi-touch functionality. It connects wirelessly to a Mac computer via Bluetooth. [4] It is powered by two AA batteries, and operates using a solid-state laser tracking sensor like the previous-generation wireless Mighty Mouse.
An important technical reason for the limitation to gesture-enhanced single-touch instead of allowing dual-touch or multi-touch is the type of sensor hardware in the display. Many touchscreen technologies obtain two independent measurements per touch to acquire a 2-dimensional position.
