We operate within an ecology of people, physical artifacts and electronic systems, and this rich ecology has recently become more complex as electronic devices invade the workplace and our day-to-day lives. We need methods to deal with these rich interactions.

• Status-event analysis is a semi-formal, easy to apply technique that:
  • classifies phenomena as event or status
  • embodies naïve psychology
  • highlights feedback problems in interfaces.
• Aspects of rich environments can be incorporated into methods such as task analysis:
  • other people
  • information requirements
  • triggers for tasks
  • modeling artifacts
  • placeholders in task sequences.
• New sensor-based systems do not require explicit interaction, this means:
  • new cognitive and interaction models
  • new design methods
  • new system architectures.
