Universal usability refers to the design of information and communications products and services that are usable for every citizen. The concept has been advocated by Professor Ben Shneiderman, a computer scientist at the Human-Computer Interaction Lab at the University of Maryland, College Park. He also provided a more practical definition of ...
Human–computer interaction (HCI) is research in the design and the use of computer technology, which focuses on the interfaces between people and computers. HCI researchers observe the ways humans interact with computers and design technologies that allow humans to interact with computers in novel ways.
Human–Computer Interaction (HCI) – the intersection of computer science and behavioral sciences — this field involves the study, planning, and design of the interaction between people (users) and computers. Attention to human-machine interaction is important, because poorly designed human-machine interfaces can lead to many unexpected ...
Design for All in the context of information and communications technology (ICT) is the conscious and systematic effort to proactively apply principles, methods and tools to promote universal design in computer-related technologies, including Internet-based technologies, thus avoiding the need for a posteriori adaptations, or specialised design.
Usability engineers sometimes work to shape an interface such that it adheres to accepted operational definitions of user requirements documentation.For example, the International Organization for Standardization approved definitions (see e.g., ISO 9241 part 11) usability are held by some to be a context, efficiency, and satisfaction with which specific users should be able to perform tasks.
Human interface guidelines often describe the visual design rules, including icon and window design and style. Much less frequently, they specify how user input and interaction mechanisms work. Aside from the detailed rules, guidelines sometimes also make broader suggestions about how to organize and design the application and write user ...
GOMS is a specialized human information processor model for human-computer interaction observation that describes a user's cognitive structure on four components. In the book The Psychology of Human Computer Interaction, [1] written in 1983 by Stuart K. Card, Thomas P. Moran and Allen Newell, the authors introduce: "a set of Goals, a set of Operators, a set of Methods for achieving the goals ...
HCC facilitates the design of effective computer systems that take into account personal, social, and cultural aspects and addresses issues such as information design, human information interaction, human-computer interaction, human-human interaction, and the relationships between computing technology and art, social, and cultural issues.
