Cognitive Desiderata for Future Interfaces

• Exploit human spatial perceptual-motor abilities.
• Major human capability - action system is second
  brain.
• Prime benefit of original GUIs, but largely
  swamped by featuritis.
• Use auditory/speech channel as parallel to
  visual/manual.
• Grossly underutilized - maybe reserved for
  human-human channel?
• But beware conflict with verbal working memory.
• Use modeling techniques to re-simplify the
  interface procedures.
• Quantitative metrics for procedural knowledge
  amount and overlap.
• No excuse for overly complicated user procedures.
• Support task memory appropriate to the skill
  level.
• Skilled performers have extremely powerful
  working memories.
• Better mapping of domain semantics to/from the
  interface.
• Enable knowledge-based inference of interaction
  procedures.
