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.
A touchpad or trackpad is a flat surface that can detect finger contact. It is a stationary pointing device, commonly used on laptop computers. At least one physical button normally comes with the touchpad, but the user can also generate a mouse click by tapping on the pad.
Aware of the finicky multitouch gestures and jumping cursors, Synaptics has been hard at work on its next generation ClickPad IS Series 3, which will be hitting laptops sometime early next year.
Synaptics is also the developer of IronVeil, a technology that allows peripheral manufacturers to incorporate fingerprint recognition into devices such as mice, keyboards, and other peripherals compatible with Windows 10.

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.
