The Center for Universal Design at NCSU established a set of Principles of Universal Design [5] based on UD to guide and evaluate the design process, with a goal toward creating more accessible products and environments. Universal Design for Instruction is an educational framework and set of strategies that applies both UD and the Principles of ...
Universal design is the design of buildings, products or environments to make them accessible to people, regardless of age, disability, or other factors. It emerged as a rights -based, anti- discrimination measure, which seeks to create design for all abilities.
For many sensory modalities, over a wide range of stimulus magnitudes sufficiently far from the upper and lower limits of perception, the 'JND' is a fixed proportion of the reference sensory level, and so the ratio of the JND/reference is roughly constant (that is the JND is a constant proportion/percentage of the reference level).
Universal design calls for "the design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design". [7] UDL applies this general idea to learning: that curriculum should, from the outset, be designed to accommodate all kinds of learners. [1]
The Differential Ability Scales (DAS) is a nationally normed (in the US), and individually administered battery of cognitive and achievement tests. Into its second edition (DAS-II), the test can be administered to children ages 2 years 6 months to 17 years 11 months across a range of developmental levels.
Evaluation measures may be categorised in various ways including offline or online, user-based or system-based and include methods such as observed user behaviour, test collections, precision and recall, and scores from prepared benchmark test sets. Evaluation for an information retrieval system should also include a validation of the measures ...
The design of tea cups and a teapot suggest their respective functions A door knob shaped to reflect how it is used, an example of perceptible affordance Affordance is one of several design principles used when designing graphical user interfaces. In psychology, affordance is what the environment offers the individual.
The Thematic Apperception Test (TAT) is a projective psychological test developed during the 1930s by Henry A. Murray and Christiana D. Morgan at Harvard University. Proponents of the technique assert that subjects' responses, in the narratives they make up about ambiguous pictures of people, reveal their underlying motives, concerns, and the ...
