- doesn't touch a11y enough
- doesn't get into practical information fast enough
2 min. Self-explanatory.
2 min. We'd like to spend the next 40 minutes discussing so-called design patterns, their history, how they're applied within various disciplines, and how working with patterns can aid design and development.
10 min. Explain Alexander's motivation behind QWAN, its ineffability. Talk about patterns, how they're found, balanced. Explain forces, contexts. Mention pattern composition. Use nice quotes. Pictures. Perhaps simple example from "A Pattern Language" here. Mention inhabitants creating patterns, and how it relates to participatory design.
5 min. Show 2 to 3 examples from "A Pattern language". Show pattern composition.
5 min. Show 2 examples from "Gang of Four" book. Simple ones. Circuit breaker. Adapter. Use pictures and real-world example to get point home. Mention how these don't tend to compose and/or expose their forces, rather - they're simply reusable solutions to common problems.
3 min. Show 2 to 3 examples from "Synthesis lectures on visualisation". Use pictures. Explain how forces aren't reflected here, but composing smaller patterns into larger patterns is essential.
10 min. Show Shneiderman eight golden rules. How it's too vague. Good basics, but not concrete enough. How to apply to an actual design challenge? Patterns are not best practices, they are more than that. Show various approaches. Borchers, Tidwell. Tognazzini. Spool? Explain different challenges when dealing with HCI.
[remaining time]. Have a prepared list of forces. Extract a pattern "DESCRIBED IMAGES" (Alt text). Show how patterns force methodical, stakeholder-balanced process. Explain how alt-text itself could refer to another pattern about readable text, "CLEAR WORDING".
Alternatively, have a pre-written pattern about image alt text. Show how it works.
