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 similar device across ...
A stored-program computer includes, by design, an instruction set, and can store in memory a set of instructions (a program) that details the computation. A stored-program design also allows for self-modifying code. One early motivation for such a facility was the need for a program to increment or otherwise modify the address portion of ...
The input–process–output model. The input–process–output (IPO) model, or input-process-output pattern, is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. Many introductory programming and systems analysis texts introduce this as the ...
v. t. e. In computing, input/output (I/O, i/o, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, such as another computer system, peripherals, or a human operator. Inputs are the signals or data received by the system and outputs are the signals or data sent from it ...
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 computer mouse with the most common features: two buttons (left and right) and a scroll wheel (which can also function as a button when pressed inwards) 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.
Point and click. Point and click are one of the actions of a computer user moving a pointer to a certain location on a screen ( pointing) and then pressing a button on a mouse or other pointing device ( click ). An example of point and click is in hypermedia, where users click on hyperlinks to navigate from document to document.
In human–computer interaction, WIMP stands for " windows, icons, menus, pointer ", [1][2][3] denoting a style of interaction using these elements of the user interface. Other expansions are sometimes used, such as substituting "mouse" and "mice" for menus, or "pull-down menu" and "pointing" for pointer. [4][5][6] Though the acronym has fallen ...
