  1. 1. Tel: (+44) 01492 879813 Mob: (+44) 07984 284642 andy@abrisk.co.uk www.abrisk.co.uk 1 Ergonomics Andy Brazier
  2. 2. About this talk Representing the Institute of Ergonomics and Human Factors (IEHF) Give you an appreciation ergonomics More than just physical characteristics How people see the world Human behaviour Ergonomics careers Not just me talking Discussion Video clips Practical. 2
  3. 3. A bit about me Self-employed consultant First encountered ergonomics when studying Design & Technology ‘O’ Level (ask your parents) ‘A’ Levels – Maths, Chemistry & Physicals Degree – Chemical Engineering Applying ergonomic principles to safety Mostly oil, gas & chemical industry. 3
  4. 4. What is Ergonomics? Comes from two Greek words "ergon", meaning work, and "nomos" meaning "laws“ What does it mean to you? 4
  5. 5. To many people Ergonomics is about the size of people 5
  6. 6. But ergonomics covers much more 6
  7. 7. Ergonomics is… The application of scientific information concerning humans: Anatomy; Physiology; Psychology. Designing objects and systems to be: Easy to use (usability); Used without error (reliability); Used without causing harm to the person or other who may be affected (health and safety). 7
  8. 8. It’s not a new idea 8 http://www.youtube.com/watch?v=dVKTX_Sbwzw YouTube – Frank Gilbreth – Bricklaying ergonomics
  9. 9. Frank Bunker Gilbreth 1885 – Motion and Fatigue Study of bricklaying Identified that stooping twice for each brick was fatiguing and slow New equipment Reduced actions per brick from 18 to 5 Increased bricks laid per hour from 125 to 350. 9
  10. 10. Let’s study this class Line up in height order Clearly the shortest and tallest people have different ‘reach distances’ Lets take the average person from the class Stand by the white board and draw lines at the highest and lowest points you can reach without stretching or bending Is this a suitable range for the class? How should we choose heights that suit all (or most) of the class? 10
  11. 11. Percentiles 11
  12. 12. Everyday ergonomics You don’t usually notice good ergonomics Easy to use You don’t need to think about how it works Bad ergonomics is more noticeable Can you think of any examples from the home? 12
  13. 13. 13 Different layout
  14. 14. 14 Designed to be slow
  15. 15. 15 Which button for which ring?
  16. 16. Group exercise How does ergonomics apply to lift (elevator) floor buttons? 16 How would you layout the buttons for A building with 5 floors A building with 30 floors The Burj Khalifa (160 floors) Are there specific users we need to accommodate? E.g. wheel chair user
  17. 17. Design is a compromise 17
  18. 18. How people see the world 18 Video - http://theinvisiblegorilla.com/gorilla_experiment.html
  19. 19. 19 What colour are the dots?
  20. 20. 20 How would you describe these lines?
  21. 21. 21 Is this animated?
  22. 22. 22 Which centre circle is largest?
  23. 23. 23 What does this say to you?
  24. 24. Understanding human perception helps us design for people 24 Middle of the screen At the edge BigSmall Colourful Contrast Flashing Loud Quiet Italics – Bold - Underline RightLeft More – Noticeable - Less
  25. 25. Human Behaviour 25 http://www.youtube.com/watch?v=Pn19FtMkeks YouTube – Sense of Urgency Video
  26. 26. Smoking room experiment Alone – 75% responded to the alarm/smoke 25% did not. In a group – only 10% responded The power of peer pressure People may not always act logically, but behaviours can be predicted. 26
  27. 27. Ergonomics careers Technology – design, usability Offices – work stations, working environment Transport - efficiency, safety Healthcare – medical devices, organisation Industry – equipment, procedures, health and safety Defence – equipment, physical and mental demands, training Sport – equipment, human performance 27
  28. 28. Ergonomics education Ergonomics as a first degree First combined with another discipline Psychology, design Second degree (MSc) Transition from another discipline Psychology Engineering Medicine Physiotherapy. 28
  29. 29. The places I work (UK) 29
  30. 30. And worldwide 30
