  • 8. Four Main Areas There are four main areas that people who use computers should focus on: 1. The Monitor 2. The Mouse & Keyboard 3. The Chair 4. The Lighting
  • 9. The Monitor • Place the monitor as far as your eyesight will allow – a minimum of 20 inches is preferred • Place the center of the screen at a 15 degree down angle from your eyes • Bend your neck slightly while keeping your head perpendicular to the floor • Line up the monitor with the keyboard
  • 10. Lighting • Your work area should be moderately bright • Do not use ‘task lighting’ • Mix incandescent and fluorescent lights to reduce flicker and provide good light color
  • 11. The Keyboard • Position the keyboard slightly below the elbows to let your wrists remain straight • Keep your hands and arms off any supports while typing • Do not use the feet on your keyboard – the flat (negative) angle keeps your wrists in the proper position
  • 12. The Mouse • Place the mouse at the same level and immediately next to the keyboard • Use your elbow, not your wrist or shoulder, to reach your mouse • Don’t rest your wrist on anything while using the mouse
  • 13. Chair Setup & Posture • Use arm rests • Adjust the height of the chair so your feet can rest completely on the floor • Allow 1-3 inches between the edge of your seat and the back of your knees • Don’t cross your ankles • Hold your head perpendicular to the floor • Let your upper arms hang naturally from your shoulders • Keep your lower arms parallel to the floor • Keep your wrists straight • Stretch!
