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 ...
Combines optical sensor with an accelerometer, allowing the mouse to track speeds in excess of 500 inches per second, and more than 16G in acceleration. 108 g (3.8 oz) (without cable) 144 g (5.1 oz) (with cable)
Optical mouse: Lyon was one of two people who independently invented the first optical mouse devices. [21] The other was Steve Kirsch, who independently invented a different type of optical mouse at MIT at approximately the same time. Both of them applied for patents on their schemes in mid-1981, and each of them received two U.S. patents (now ...
Jean-Daniel Nicoud (born 31 August 1938), is a Swiss computer scientist, noted for inventing a computer mouse with an optical encoder and the CALM (Common Assembly Language for microprocessors). [1] He obtained a degree in physics at the École Polytechnique Fédérale de Lausanne (EPFL) in 1963. Around 1965, he became interested in logical ...
Paul, Matthias R. (2002-04-06). "Re: [fd-dev] ANNOUNCE: CuteMouse 2.0 alpha 1".freedos-dev.Archived from the original on 2020-02-07 […] The original Mouse Systems Bus Mouse is a normal serial 8250 compatible mouse using the normal Mouse Systems serial protocol, however the base address of this 8250 type chip is not one of the usual COM port addresses 3F8h, 2F8h, 3E8h, or 2E8h, but either ...
The use of mousepads with precision surfaces eliminates the spot-jitter effects of older and/or low-quality optical mice. Wireless charging mousepad from Logitech. Newer generations of mouse pads incorporate a wireless charging system into the pad, allowing a wireless mouse to be used without the need to replace or recharge batteries. [10]
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. Optical pointing sticks are also used on some Ultrabook tablet hybrids, such as the Sony Duo 11, ThinkPad Tablet and Samsung Ativ Q.
A laser mouse is an optical mouse that uses coherent (laser) light. The earliest optical mice detected movement on pre-printed mousepad surfaces, whereas the modern LED optical mouse works on most opaque diffuse surfaces; it is usually unable to detect movement on specular surfaces like polished stone.
