Transcript

  • 1. Introduction to Cognitive Ergonomics
  • 2. How do you make a copy from this machine?
  • 3. What do the symbols mean?
  • 4. COGNITIVE ERGONOMICS
    • Focuses on the design of the interface between humans and work in accordance with the user’s cognitive constraints
    • Applications include design of complex, high-tech, or automated systems.
  • 5. B-17 Cockpit
  • 6. COGNITIVE ERGONOMICS
    • Cognitive ergonomics assumes that your physical setting affects your ability to think, to be creative, to make connections. (Source: http://hackvan.com/brain/msg00076.htm )
  • 7. COGNITIVE ERGONOMICS
    • Study of all human activities related to knowledge , that influence or are influenced by the design of machines , work systems and objects that people use, the associated work processes, and the environments in which they operate.
    • The study of human thinking in the work context (Fitter and Sime, 1978)
  • 8. Cognition
  • 9. Cognition
    • Refers to all the processes by which sensory input is transformed, reduced, elaborated, stored, recovered, and used.
  • 10. HF vs. Experimental Psych
    • Goal of HF:
      • To apply knowledge in designing systems that work, accommodating human limits, and exploiting the advantages of a human operator as well
    • Goal of Experimental Psychology:
      • To uncover the laws of behavior thru experiments.
      • Experimental design unconstrained by any requirement for application
  • 11. Intersection
    • Engineering psychology is the intersection of human factors and experimental psychology
    Expt’al Psych HF Eng Psych
  • 12. HF, not Eng Psych
    • There are areas of HF that are not Eng Psych
    • Physical ergonomics
      • Work physiology
      • Manual-materials handling
      • Anthropometry
      • Environment: Illumination, atmospheric conditions, noise, motion
    • Issues of muscle fatigue, whether someone can fit in a cockpit, how bright the work environment is
  • 13. HF, not Eng Psych
    • Concern physical properties of worker’s body, not brain’s information processing capabilities
    • These are all HF concerns, but are not Eng Psych
  • 14. Issues in Cognitive Ergonomics
    • Humans interaction with technology
    • Influence of cognitive tasks in the interaction with technology
    • Design to ensure well being
  • 15. A Global Positioning System
  • 16. How do I make a call?
  • 17. Good ergonomics may prevent this!
  • 18. Human-Machine System: Psych View
  • 19. References
    • Wickens, C. & Carswell, M. 1997. Information processing, In G. Salvendy Handbook of Human Factors and Ergonomics , John Wiley, NY.
