Optical mouse. A Microsoft wireless optical mouse. An optical mouse is a computer mouse which uses a miniature camera and digital image processing to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse and its need for frequent cleaning. The earliest optical mice detected ...
The first commercial digital camera, the Cromemco Cyclops in 1975, used a 32×32 MOS image sensor. It was a modified MOS dynamic RAM memory chip. [35] MOS image sensors are widely used in optical mouse technology. The first optical mouse, invented by Richard F. Lyon at Xerox in 1980, used a 5 μm NMOS integrated circuit sensor chip.
A 3D mouse is a computer input device for viewport interaction with at least three degrees of freedom , e.g. in 3D computer graphics software for manipulating virtual objects, navigating in the viewport, defining camera paths, posing, and desktop motion capture. 3D mice can also be used as spatial controllers for video game interaction, e.g ...
New "Hero" sensor is a completely new sensor developed by Logitech. The sensor is optimized for precision and power efficiency. The mouse has no customizable lighting to increase battery life. 88.9 g (3.14 oz) (mouse only) 112.3 g (3.96 oz) (with 1 AA battery) 135.7 g (4.79 oz) (with 2 AA batteries) G PRO Wireless.
Optical flow sensors are used extensively in computer optical mice, as the main sensing component for measuring the motion of the mouse across a surface. Optical flow sensors are also being used in robotics applications, primarily where there is a need to measure visual motion or relative motion between the robot and other objects in the ...
An active-pixel sensor (APS) is an image sensor, which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. [1][2] In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers.
