Presentation Transcript

  1. Ecological Approaches • Appropriate for design of systems to support human operators in complex, dynamic environments. • Founded on ecological psychology • “Simon’s Ant” example • Contrast with cognitivist approaches • Requires understanding of the system and environment within which the operator is working.

  2. Option 1 Option 2 An example – “shoe tying machine”

  3. Ecological Interface Design (EID) • Based on the SRK taxonomy • Focus is on environmental constraints and system function

  4. Understanding work: Abstraction Hierarchy

  5. Using the AH in interface design

  6. An Example • DURESS (DUal REservoir Simulation System) • Process control example • Small feedwater stream • 6 valves, 2 pumps, 2 heaters (from: Vicente, K.J. and Rasmussen, J. (1990) The ecology of human machine systems II: Mediating direct perception in complex work domains. Ecological Psychology, 2(3), pp.207-249)

  7. DURESS (cont.)

  8. DURESS “Standard” Configuration

  9. DURESS Redesign Based on EID

  10. Your Turn: Car Dashboard • Allow the driver to monitor and control car speed for optimal fuel consumption.

  11. An example – Prius console • “energy” view
