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 movement on prepared surfaces, however they never gained ...
Richard F. Lyon. Richard " Dick " Francis Lyon (born 1952) is an American inventor, scientist, and engineer. He is one of the two people who independently invented the first optical mouse devices in 1980. [1][2][3] He has worked in signal processing and was a co-founder of Foveon, Inc., a digital camera and image sensor company.
Optogenetics. Optogenetics is a biological technique to control the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells. On the level of individual cells, light-activated enzymes and transcription factors allow precise control of ...
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.
Scientists track eye movements in glaucoma patients to check vision impairment while driving. Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movement. Eye trackers are used in research on the ...
A computer mouse (plural mice, also mouses) [ nb 1 ] is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a computer.
An elder 3D mouse. 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 ...
The 90-minute presentation demonstrated for the first time many of the fundamental elements of modern personal computing: windows, hypertext, graphics, efficient navigation and command input, video conferencing, the computer mouse, word processing, dynamic file linking, revision control, and a collaborative real-time editor. Engelbart's ...
