Lecture1 Intro To Cog Ergo

  1. 1. Introduction to Cognitive Ergonomics
  2. 2. How do you make a copy from this machine?
  3. 3. What do the symbols mean?
  4. 4. COGNITIVE ERGONOMICS <ul><li>Focuses on the design of the interface between humans and work in accordance with the user’s cognitive constraints </li></ul><ul><li>Applications include design of complex, high-tech, or automated systems. </li></ul>
  5. 5. B-17 Cockpit
  6. 6. COGNITIVE ERGONOMICS <ul><li>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 ) </li></ul>
  7. 7. COGNITIVE ERGONOMICS <ul><li>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. </li></ul><ul><li>The study of human thinking in the work context (Fitter and Sime, 1978) </li></ul>
  8. 8. Cognition
  9. 9. Cognition <ul><li>Refers to all the processes by which sensory input is transformed, reduced, elaborated, stored, recovered, and used. </li></ul>
  10. 10. HF vs. Experimental Psych <ul><li>Goal of HF: </li></ul><ul><ul><li>To apply knowledge in designing systems that work, accommodating human limits, and exploiting the advantages of a human operator as well </li></ul></ul><ul><li>Goal of Experimental Psychology: </li></ul><ul><ul><li>To uncover the laws of behavior thru experiments. </li></ul></ul><ul><ul><li>Experimental design unconstrained by any requirement for application </li></ul></ul>
  11. 11. Intersection <ul><li>Engineering psychology is the intersection of human factors and experimental psychology </li></ul>Expt’al Psych HF Eng Psych
  12. 12. HF, not Eng Psych <ul><li>There are areas of HF that are not Eng Psych </li></ul><ul><li>Physical ergonomics </li></ul><ul><ul><li>Work physiology </li></ul></ul><ul><ul><li>Manual-materials handling </li></ul></ul><ul><ul><li>Anthropometry </li></ul></ul><ul><ul><li>Environment: Illumination, atmospheric conditions, noise, motion </li></ul></ul><ul><li>Issues of muscle fatigue, whether someone can fit in a cockpit, how bright the work environment is </li></ul>
  13. 13. HF, not Eng Psych <ul><li>Concern physical properties of worker’s body, not brain’s information processing capabilities </li></ul><ul><li>These are all HF concerns, but are not Eng Psych </li></ul>
  14. 14. Issues in Cognitive Ergonomics <ul><li>Humans interaction with technology </li></ul><ul><li>Influence of cognitive tasks in the interaction with technology </li></ul><ul><li>Design to ensure well being </li></ul>
  15. 15. A Global Positioning System
  16. 16. How do I make a call?
  17. 17. Good ergonomics may prevent this!
  18. 18. Human-Machine System: Psych View
