  2. RGB color model - Wikipedia

    en.wikipedia.org/wiki/RGB_color_model

    The RGB color model itself does not define what is meant by red, green, and blue colorimetrically, and so the results of mixing them are not specified as absolute, but relative to the primary colors. When the exact chromaticities of the red, green, and blue primaries are defined, the color model then becomes an absolute color space , such as ...

  3. Context-sensitive user interface - Wikipedia

    en.wikipedia.org/wiki/Context-sensitive_user...

    Context sensitive actions may be perceived as dumbing down of the user interface, leaving the operator at a loss as to what to do when the computer decides to perform an unwanted action. Additionally non-automatic procedures may be hidden or obscured by the context sensitive interface causing an increase in user workload for operations the ...

  5. Computer mouse - Wikipedia

    en.wikipedia.org/wiki/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 computer. The first public ...

  6. Cursor (user interface) - Wikipedia

    en.wikipedia.org/wiki/Cursor_(user_interface)

    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.

  7. List of monochrome and RGB color formats - Wikipedia

    en.wikipedia.org/wiki/List_of_monochrome_and_RGB...

    This list of monochrome and RGB palettes includes generic repertoires of colors (color palettes) to produce black-and-white and RGB color pictures by a computer's display hardware. RGB is the most common method to produce colors for displays; so these complete RGB color repertoires have every possible combination of R-G-B triplets within any ...

  8. Pointing stick - Wikipedia

    en.wikipedia.org/wiki/Pointing_stick

    The velocity of the pointer depends on the applied force so increasing pressure causes faster movement. The relation between pressure and pointer speed can be adjusted, just as mouse speed is adjusted. On a QWERTY keyboard, the stick is typically embedded between the G, H and B keys, and the mouse buttons are placed just below the space bar ...

  9. Optical mouse - Wikipedia

    en.wikipedia.org/wiki/Optical_mouse

    An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse design, which uses moving parts to sense motion.
