The most important idea is testing the user experience according to the following five "laws" of human-computer interaction:
1. Fitt's Law (of movement to a target area): https://en.wikipedia.org/wiki/Fitts%27s_law https://en.wikipedia.org/wiki/Fitts%27s_law
2. Steering Law (of movement through a tunnel): https://en.wikipedia.org/wiki/Steering_law https://en.wikipedia.org/wiki/Steering_law
3. Hick's Law (of choices and decision time): https://en.wikipedia.org/wiki/Hick%27s_law https://en.wikipedia.org/wiki/Hick%27s_law
4. Miller's Law (of working memory): https://en.wikipedia.org/wiki/Miller%27s_law https://en.wikipedia.org/wiki/Miller%27s_law
5. Power Law (of practice and reaction time): https://en.wikipedia.org/wiki/Power_law_of_practice https://en.wikipedia.org/wiki/Power_law_of_practice
- grandalf 12y agoThis is awesome. I'm imagining a fluffy UX/design conversation being replaced by a proof.
- 21echoes 12y agoIn my time working with designers, almost all of them refer constantly to these rules (esp. Fitt's, Hick's, and Miller's which basically reduce to "big buttons", "few choices", and "no memory required", respectively). However, these laws are just constraints and trade-offs -- most of the time your competing candidate designs will follow them an equivalent amount. At that point, most designers don't reach for "proof", but rather for "evidence", e.g. user research studies.
