CS295J/Model elements

• Internal verbal working memory
  • need some individual notion of chunking
  • may need some individual notion of capacity
  • cognitive testing may help to fill these values in
• Internal visual working memory
• External working memory (perhaps as an "extended mind" concept)
• Long-term memory
• Attention and interruption
• Causal perception
  • how people perceive relations among things that affect one another
  • cued by spatial and temporal contiguity
  • can make interfaces more intuitive and easier to learn
• Affordances
  • the appearance of an interface component should invoke its function
  • e.g. elements that can be moved and manipulated should have a handle
• ???

We need some kind of a framework where we can assemble all of these elements so that they can be coupled, extended, connected to users, connected to user interfaces, etc.
