There is a large body of accumulated research knowledge on UI design, but it is hard to remember it all and even harder to use. UI Tenets & Traps is a tool attempting to synthesize this accumulated knowledge and put it in a form which practitioners can take action on. They are a general purpose UI evaluation tool, meant to be used to improve the quality of UI design early in the product life cycle.
- describe general attributes of good interface design.
- describe common design problems that degrade this goodness. Reduce Traps and the experience improves.
UI Tenets & Traps has several strengths as a UI evaluation tool:
- They are distilled from a large body of existing UI heuristic tools and research.
- They explain why UI problems exist rather than simply identifying problems.
- They facilitate communication through common language.
- They can explain user performance and satisfaction.
- Since they are a deck of cards, they are portable and practical.
