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.
The mouse gesture for "back" in Opera – the user holds down the right mouse button, moves the mouse left, and releases the right mouse button.. In computing, a pointing device gesture or mouse gesture (or simply gesture) is a way of combining pointing device or finger movements and clicks that the software recognizes as a specific computer event and responds to accordingly.
Placing one or two fingers across the plates achieves a turn on or closed state. Removing the finger(s) from the metal pieces turns the device off. One implementation of a resistance touch switch would be two Darlington-paired transistors where the base of the first transistor is connected to one of the electrodes.
Media controls on a multimedia keyboard. From top; left to right: skip backward, skip forward, stop, play/pause. Media control symbols are commonly found on both software and physical media players, remote controls, and multimedia keyboards.
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.
A pointing stick on a mid-1990s-era Toshiba laptop. The two buttons below the keyboard act as a computer mouse: the top button is used for left-clicking while the bottom button is used for right-clicking. Optical pointing sticks are also used on some Ultrabook tablet hybrids, such as the Sony Duo 11, ThinkPad Tablet and Samsung Ativ Q.
The TouchPad has three separate physical buttons, a sleep/wake button on the top right, a home button at the bottom of the front that launches the card view or the app launcher and a set of volume rockers at the right of the device. Holding the power button and the home button together creates a screen snapshot.
A mouse button is an electric switch on a computer mouse which can be pressed (“clicked”) to select or interact with an element of a graphical user interface. Mouse buttons are most commonly implemented as miniature snap-action switches (micro switches). The three-button scrollmouse has become the most commonly available design.
