One mickey is the smallest resolvable unit of distance by a given computer mouse pointing device. It is named after Walt Disney's Mickey Mouse cartoon character. [15] Mouse motion is reported in horizontal and vertical mickeys. Device sensitivity is usually specified in mickeys per inch.
There also exists a mouse adapter which converts a conventional mouse to a footmouse that slides and horizontally tilts to one side. A footmouse that uses sliding can be a slipper with a mouse connected to it, or a special frame in which a pedal can move around. Also a tiny magnet or other location device can be used on a tablet. A footmouse ...
A typical wireless computer mouse. 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 ...
In February 2009, Microsoft released another update to the SideWinder line, the SideWinder X8 gaming mouse. This new iteration incorporated new Microsoft BlueTrack tracking technology, intended to provide better tracking on non-standard surfaces. In addition, the mouse was made wireless, and the maximum DPI sensitivity was upped to 4000. [16]
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 CIE photopic luminous efficiency function y(λ) or V(λ) is a standard function established by the Commission Internationale de l'Éclairage (CIE) and standardized in collaboration with the ISO, [ 1] and may be used to convert radiant energy into luminous (i.e., visible) energy. It also forms the central color matching function in the CIE ...
Image sensor. An image sensor or imager is a sensor that detects and conveys information used to form an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information.
Medical usage. In medical diagnosis, test sensitivity is the ability of a test to correctly identify those with the disease (true positive rate), whereas test specificity is the ability of the test to correctly identify those without the disease (true negative rate). If 100 patients known to have a disease were tested, and 43 test positive ...
