Cocoa is Apple 's native object-oriented application programming interface (API) for its desktop operating system macOS . Cocoa consists of the Foundation Kit, Application Kit, and Core Data frameworks, as included by the Cocoa.h header file, and the libraries and frameworks included by those, such as the C standard library and the Objective-C ...
User interfaces that dispense with the physical movement of body parts as an intermediary step between the brain and the machine use no input or output devices except electrodes alone; they are called brain–computer interfaces (BCIs) or brain–machine interfaces (BMIs). Other terms for human–machine interfaces are man–machine interface ...
A graphical user interface, or GUI ( / ˈɡuːi / [1] [2] GOO-ee ), is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based UIs, which are based on typed command labels or text navigation.
Category. The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles. Several vendors have created their own windowing systems based on independent code, but with basic elements in ...
Quartz 2D is the primary two-dimensional (2D) text and graphics rendering library: It directly supports Aqua by displaying two-dimensional graphics to create the user interface, including on-the-fly rendering and anti-aliasing. Quartz can render text with sub-pixel precision; graphics are limited to more traditional anti-aliasing, which is the ...
Quartz 2D is available to all macOS and iOS application environments and provides resolution-independent and device-independent rendering of bitmap graphics, text, and vectors both on-screen and in preparation for printing. Its responsibilities within the graphics layer include: [1] Rendering text. Displaying, manipulating, and rendering PDF ...
UI design refers to graphical user interfaces and other forms of interface design. The goal of user interface design is to make the user 's interaction as simple and efficient as possible, in terms of accomplishing user goals ( user-centered design ). User interfaces are the points of interaction between users and designs. There are three types:
