Ergonomics

What is Ergonomics?

Ergonomics is the applied science that seeks to improve the design and function of tools and other objects used by people. Ergonomics evaluate the interaction between humans and these objects. By understanding the range and capability of the human body, ergonomics work to optimize the efficiency and safety of these interactions.

Why Care About Ergonomics

By understanding basic ergonomics and its interaction with your job, you can help prevent injuries to yourself, work more efficiently and comfortably, and promote your long-term health.(link sends e-mail)

Elements of an Ideal Computer Workstation

Workstation Ergonomics

Ergonomic position of monitor

Viewing Angles and Distance

  • Position monitor, keyboard, and chair in straight line
  • Top of monitor screen at or slightly below the eye horizon
  • Comfortable, non-straining distance to read monitor (typically 15-30 inches)
  • Adjust brightness, contrast, and color to comfortable levels
  • Avoid glare by positioning away from windows and direct lights
  • Keep written work materials propped up near monitor screen

Ergonomic typing positionNeutral Typing Position

  • Use an adjustable chair, keyboard tray, or desk/table to achieve the "neutral position" of a straight hand: wrist: forearm
  • Keep upper and lower arms at a 90 degree angle to each other
  • Position mouse as closely to keyboard as possible to minimize reaching and twisting

Ergonomic lower back support positionLower Back Support

  • Use a chair that provides lumbar (lower back) support - if adjustable, adjust to maintain an erect sitting posture
  • Ideal chairs can be easily raised or lowered
  • Ideal chairs have 5 wheel legs for safety
  • Keep feet planted firmly on floor or footstool to counterbalance forces on lower back

Ergonomic position of legs and feetLegs and Feet

  • Plant feet firmly on floor or - if not possible - use a foot stool
  • Keep thighs parallel to floor
  • Ensure leg clearance from table or keyboard tray to avoid bumps, scratches, pinches, and torn clothing
If you have an ergonomic concern about your workstation or other repetitive motion task, please contact a member of the committee to set up an evaluation or visit the following Web sites for more information.
