I attended a talk of Dr Alex Mitchell from NUS on UI and UX Design
Mental models and interaction
= Players build up a mental model of how a UI works
= Players use this to decide how to interact.
= Mental models are developed through interaction
= Inaccurate mental model can lead to problems
Design principles (from Don Norman)
1. Affordances and visibility (what and how can I do it?)
== Connection between core mechanic and player
== Remember, player will be doing this over and over
2. Feedback
== What happened when I did something?
== Was the action successful? What should I do next?
3. Mapping
== How did my action relate to what happened?
== Helps the player figure out how to play to win...
4. Consistency and Convention
== Make sure interaction is consistent throughout the game, and across the platform
== build on conventions that your players know, e.g. how to select menu items
5. Focus of attention
== Players will be intently focused on the action in the game
== Take advantage of this when designing the UI
