Monitor proofing or soft-proofing is a step in the prepress printing process. It uses specialized computer software and hardware to check the accuracy of text and images used for printed products. Monitor proofing differs from conventional forms of “hard-copy” or ink-on-paper color proofing in its use of a calibrated display(s) as the ...
The term mouse tracking originally referred to how movements were captured and transmitted to the computer. For example, the original tracker ball mouse used a metal bearing pressed against two rollers to track movement. [2] Much research and technology has gone into what type of tracker provides the most accurate depiction of the user's movement.

Computer mouse is another common USB HID class device. USB HID mice can range from single-button simple devices to multi-button compound devices. Most modern operating systems ship with drivers for standard HID mouse designs (the most common modern mouse design has two dedicated buttons and a mouse wheel that doubles as the third button); mice ...
Applications with screen logging abilities may take screenshots of the whole screen, of just one application, or even just around the mouse cursor. They may take these screenshots periodically or in response to user behaviors (for example, when a user clicks the mouse). Screen logging can be used to capture data inputted with an on-screen keyboard.
These keys can be selected using the mouse or another pointing device, or a single key or small group of keys can be used to cycle through the keys on the screen. The on-screen keyboard is the most common type of virtual keyboard. The accuracy of this keyboard depends only on hitting the right key.
The user can continue interaction right from the current mouse position and doesn't have to move to a different preset area. Many operating systems use this when displaying right-click context menus. As the menu starts right on the pixel which the user clicked, this pixel is referred to as the "magic" or "prime pixel".
An early Xerox optical mouse chip, before the development of the inverted packaging design of Williams and Cherry. The first two optical mice, first demonstrated by two independent inventors in December 1980, had different basic designs: [1] [2] [3] One of these, invented by Steve Kirsch of MIT and Mouse Systems Corporation, [4] [5] used an infrared LED and a four-quadrant infrared sensor to ...
