IBM sold a mouse with a pointing stick in the location where a scroll wheel is common now. 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.
An elder 3D mouse. 3D pointing device. A pointing device is a human interface device that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. Graphical user interfaces (GUI) and CAD systems allow the user to control and provide data to the computer using physical gestures by moving a hand-held mouse or ...
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.
A user presses a key which transfers information to a computer. In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance. Examples of input devices include keyboards, computer mice, scanners, cameras, joysticks, and microphones .
A typical wireless computer mouse. A computer mouse (plural mice, also mouses) [ nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a ...
A computer keyboard is a peripheral input device modeled after the typewriter keyboard [1] [2] which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter -style keyboards have been the main input method for computers since ...
Control key. In computing, a Control key Ctrl is a modifier key which, when pressed in conjunction with another key, performs a special operation (for example, Ctrl + C ). Similarly to the Shift key, the Control key rarely performs any function when pressed by itself. The Control key is located on or near the bottom left side of most keyboards ...
In computing, a pointer or mouse pointer (as part of a personal computer WIMP style of interaction) [10] [11] [12] is a symbol or graphical image on the computer monitor or other display device that echoes movements of the pointing device, commonly a mouse, touchpad, or stylus pen. It signals the point where actions of the user take place.
