We need to be very careful when talking about contexts — design decisions related to context must be based on fact rather than assumption. For example, a context-based assumption would be to change the language of a Web page in response to the location of a device — a terrible idea because the reader might speak a language that isn’t native to the detected country.
…expressed perfectly by xkcd:
Dyslexia causes the reader to see letters as real world objects, influenced by gravity, motion and mistaken identity (letters of the alphabet do look pretty similar!).
Working with this trait, the designers of Dyslexie use fat bottoms, longer necks and accentuated curves to make it easier for readers to recognise differences between letters.
Interesting article on getting useful feedback from users:
- Tell users at the start what sort of feedback you need
- Offer encouragement only when they give you the useful kind of information
- Change the subject if the user derails to the not-useful kind of information
