Cognitive dimensions are design principles for notations & programming language design, described by researcher Thomas R.G. Green. The dimensions can be used to evaluate the usability of an existing interface, or as heuristics to guide the design of a new one.
List of the cognitive dimensionsEdit
- abstraction gradient
- closeness of mapping
- hard operations: hard mental processing
- hidden dependencies
- premature commitment
- progressive evaluation
- secondary notation & escape from formalism
- viscosity: difficulty making changes
- side by side ability: making comparisons (juxtaposability)
