- CVD Simulation(also: Colour Blindness Simulation, Color Vision Simulation)
- A technique that transforms colours in a design to approximate how they would appear to a person with a specific type of colour vision deficiency. CVD simulations are the most widely implemented feature in accessibility design tools, available in browsers (Chrome, Firefox),…
- CogTool
- A cognitive modeling tool developed at Carnegie Mellon University that generates quantitative predictions of human task performance times based on the Keystroke-Level Model (KLM) and the ACT-R cognitive architecture. Designers create storyboards of user interface screens and…
- Colour Palette Generation(also: Color Palette Generation, Accessible Palette Generation)
- The automated or semi-automated creation of sets of colours that are distinguishable by people with different types of colour vision deficiency while meeting aesthetic and functional design requirements. Despite its importance, colour palette generation is an underrepresented…
- Computer-Aided Design(also: CAD)
- The use of software to create, modify, analyse, and optimise designs for physical objects or systems. In accessibility contexts, CAD tools are critical for designing assistive technology, tactile graphics, and 3D printable models, but most commercial CAD applications rely…
