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 ...
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 ...
IntelliMouse Explorer 3.0 Microsoft IntelliMouse with IntelliEye optical sensor mouse. IntelliMouse is a series of computer mice from Microsoft.The IntelliMouse series is credited with a number of innovations; [1] Microsoft was among the first mouse vendors to introduce a scroll wheel, [2] an optical mouse, and dedicated auxiliary buttons on the side of the mouse.
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. [33] [34] Since the first commercial optical mouse, the IntelliMouse introduced in 1999, most optical mouse devices use CMOS sensors. [35]

Many types of sensors use capacitive sensing, including sensors to detect and measure proximity, pressure, position and displacement, force, humidity, fluid level, and acceleration. Human interface devices based on capacitive sensing, such as touchpads , [ 1 ] can replace the computer mouse .
A trackball is a pointing device consisting of a ball housed in a socket containing sensors to detect rotation of the ball about two axis, similar to an upside-down mouse: as the user rolls the ball with a thumb, fingers, or palm the pointer on the screen will also move. Tracker balls are commonly used on CAD workstations for ease of use, where ...
In 2005, Lyon was awarded the Progress Medal of the Royal Photographic Society, along with Carver Mead and Richard B. Merrill of Foveon, for the development of the Foveon X3 sensor. [33] In 2005, Lyon became one of the people featured in George Gilder's book, The Silicon Eye, which covered the development of the Foveon X3 sensor. [34]
