Usability inspectionUsability inspection is the name for a set of methods where an evaluator inspects a user interface. This is in contrast to usability testing where the usability of the interface is evaluated by testing it on real users. Usability inspections can generally be used early in the development process by evaluating prototypes or specifications for the system that can't be tested on users. Usability inspection methods are generally considered to be less costly to implement than testing on users. Usability inspecti
Transgenerational designTransgenerational design is the practice of making products and environments compatible with those physical and sensory impairments associated with human aging and which limit major activities of daily living. The term transgenerational design was coined in 1986, by Syracuse University industrial design professor James J. Pirkl to describe and identify products and environments that accommodate, and appeal to, the widest spectrum of those who would use them—the young, the old, the able, the disabled—without penalty to any group.
AffordanceIn psychology, affordance is what the environment offers the individual. In design, affordance has a narrower meaning, it refers to possible actions that an actor can readily perceive. American psychologist James J. Gibson coined the term in his 1966 book, The Senses Considered as Perceptual Systems, and it occurs in many of his earlier essays. His best-known definition is from his 1979 book, The Ecological Approach to Visual Perception:The affordances of the environment are what it offers the animal, what it provides or furnishes, either for good or ill.
Contextual designContextual design (CD) is a user-centered design process developed by Hugh Beyer and Karen Holtzblatt. It incorporates ethnographic methods for gathering data relevant to the product via field studies, rationalizing workflows, and designing human–computer interfaces. In practice, this means that researchers aggregate data from customers in the field where people are living and applying these findings into a final product. Contextual design can be seen as an alternative to engineering and feature driven models of creating new systems.
Cognitive dimensions of notationsCognitive dimensions or cognitive dimensions of notations are design principles for notations, user interfaces and programming languages, described by researcher Thomas R.G. Green and further researched with Marian Petre. The dimensions can be used to evaluate the usability of an existing information artifact, or as heuristics to guide the design of a new one, and are useful in Human-Computer Interaction design. Cognitive dimensions are designed to provide a lightweight approach to analyse the quality of a design, rather than an in-depth, detailed description.
