  1. 1. © 2013 Jennifer Long Visual Ergonomics 1/09/2013 1 Visual Ergonomics: A different focus for safety, comfort and productivity Jennifer Long Jennifer Long Visual Ergonomics www.visualergonomics.com.au In this presentation… • What is visual ergonomics and why is it  important in our workplaces? • What are some of the visual ergonomics issues  emerging in our workplaces? • How can we manage these issues: • In the short term? • In the long term? What is ergonomics/human factors? Human  needs,  capabilities  and  limitations Work,  product,  environment Safe Comfortable Productive
  2. 2. © 2013 Jennifer Long Visual Ergonomics 1/09/2013 2 What is Visual Ergonomics? Visual  capabilities  and  perception Displays, Lighting, Signage Safe Comfortable Productive Imbalance leads to: Asthenopia (“eye strain”) Headaches Sore eyes Red eyes Blurry vision Decreased  productivity Accident / injury Dissatisfaction Increased cost Common visual ergonomics issues in our workplaces
  3. 3. © 2013 Jennifer Long Visual Ergonomics 1/09/2013 3 1. Poor posture: our posture is driven by detail / font size 2. Displays too wide: We turn our head to view objects beyond 15 degrees 3. Displays too high: It is easier to focus when looking down
  4. 4. © 2013 Jennifer Long Visual Ergonomics 1/09/2013 4 4.Some colour combinations are difficult to view Red / blue combination Red / green combination Grey / pink combination Red / black combination Colour vision defects • 1 in 12 males • 1 in 200 females Our workplaces are a collection of individuals
  5. 5. © 2013 Jennifer Long Visual Ergonomics 1/09/2013 5 Not everyone sees the world the same way We have an ageing workforce 47% working age people in NSW are aged  40‐64 (ABS) Born after 1957? You can’t retire until you are 67! What does this mean for the workplace? Individuals may: • Have difficulties seeing near tasks • Have difficulties seeing in the distance • Want more light to see • Be more glare sensitive – and want less light • Be more likely to experience ocular discomfort  e.g. dry eye • Have eye diseases which impact on visual function
  6. 6. © 2013 Jennifer Long Visual Ergonomics 1/09/2013 6 Short term strategy: Manage each problem on an individual basis Longer term strategy: Build in adjustability Adjustability for visual comfort • We are already used to this concept for furniture • Adjustable lighting • Adjustable display position • Adjustable display colours and fonts
  7. 7. © 2013 Jennifer Long Visual Ergonomics 1/09/2013 7 “But these products don’t exist for my business…” Evidence base When you are next purchasing a product, ask: • Can the end user easily adjust it? • Will it allow a good physical and visual posture?
  8. 8. © 2013 Jennifer Long Visual Ergonomics 1/09/2013 8 Include visual ergonomics in design specifications • This may require research to establish an  evidence base • Formalises and acknowledge these issues Summary Visual  capabilities  and  perception Displays, Lighting, Signage Safe Comfortable Productive
