2 Defining Ergonomics The Science of studying people at work, and then designing the working environment to ensure that they can be safe, healthy, effective and comfortable. GOAL IS TO fit the job to the worker NOT TO fit the worker to the job

3 Your Chair The Base 5 casters (more stable) Casters within circumference of seat pan Use hard casters for soft floors (carpet) Use soft casters for hard floors (tile)

4 Your Chair The Seat Pan Rounded front edge (waterfall) Reduce chance of contact stress at the back of the knees and thighs Adjustable seat slope Forward or backward tilt Adjustable seat pan depth

5 Your Chair The Fist Test

6 Your Chair The Fist Test Buttock-to-Popliteal Length: Buttock-to-popliteal length is measured as the horizontal distance from the back of the buttock to the back of the knee This value defines the maximum seat depth for a chair to ensure that pressure on the underside of the thigh is not excessive

7 Your Chair The Fist Test

8 Your Chair The Fist Test

9 Your Chair Seat Height Measure the vertical distance from the floor to the underside of the knee Front of knees level or slightly below the top of the chair

10 Your Chair Seat Height

11 Your Chair Armrests Allows shoulders to relax Supports arm weight Relieves neck tension Adjustable Width adjustability option Height Slide forward and backward Can be changed/removed

12 Your Chair - Summary Always choose comfort and function over aesthetics Purchase adjustable equipment

13 Keyboard Trays Want elbow joint at 90 with shoulders relaxed Some may feel more comfortable with elbow joint greater than 90 Keep arms close to body

14 No Keyboard Tray? Average Desk Height = 75cm Men Anthropometric Data Seated Elbow Height Women Anthropometric Data Seated Elbow Height

15 Keyboard Trays to Avoid

16 Keyboard Trays to Avoid Tray with slide-out platform for the mouse: tray is unsteady, and causes user to lean on the right hip Rail keyboard trays: are not adjustable in height or angle Small keyboard trays: no space for the mouse, which causes user to place the mouse on the desk

17 Ideal Keyboard Trays Sturdy surface Angle and height adjustability 65 cm in width

18 Wrist Rest Improves wrist angle while typing and reduces pressure point on wrists

19 Screen Height - AVOID When the monitor is too low, the neck is flexed When the monitor to too high, the neck is extended When the monitor is not directly in front of the user, the neck is twisted

20 Screen Height - Ideal The monitor should be: Directly in front of user Situated at seated eye level Arm s length away from user
