A mouse click is the action of pressing (i.e. 'clicking', an onomatopoeia) a button to trigger an action, usually in the context of a graphical user interface (GUI). “Clicking” an onscreen button is accomplished by pressing on the real mouse button while the pointer is placed over the onscreen button's icon.
The scroll wheel on a mouse has been invented multiple times by different people unaware of the others' work. Other scrolling controls on a mouse, and the use of a wheel for scrolling both precede the combination of wheel and mouse. The earliest known example of the former is the Mighty Mouse prototype developed jointly by NTT, Japan and ETH Zürich, Switzer
In computing, a pointer or mouse pointer (as part of a personal computer WIMP style of interaction) [10] [11] [12] is a symbol or graphical image on the computer monitor or other display device that echoes movements of the pointing device, commonly a mouse, touchpad, or stylus pen. It signals the point where actions of the user take place.
In optics, chromatic aberration (CA), also called chromatic distortion, color aberration, color fringing, or purple fringing, is a failure of a lens to focus all colors to the same point. [ 1 ] [ 2 ] It is caused by dispersion : the refractive index of the lens elements varies with the wavelength of light .
Block diagram of the signal-flow for a common feedback loop [1]: 118 . Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup).
They can result from improper clock sources [3] and buffer size. Also, clicks can be caused by electric devices near the computer or by faulty audio or mains cables. [4] In sample recording, digital clicks occur when the signal levels of two adjacent audio sections do not match. The abrupt change in gain can be perceived as a click. [5]
The Leslie speaker is a combined amplifier and loudspeaker that projects the signal from an electric or electronic instrument and modifies the sound by rotating a baffle chamber ("drum") in front of the loudspeakers. A similar effect is provided by a rotating system of horns in front of the treble driver.
The mouse has approximately 2.7 billion base pairs and 20 pairs of chromosomes. [12] They can also be manipulated in ways that are illegal with humans, although animal rights activists often object. A knockout mouse is a genetically modified mouse that has had one or more of its genes made inoperable through a gene knockout.
