Background of Ergonomics

Ergonomics – How people relate to their work & home environments.– For you this means school.

Ergonomics is partly physical, and partly environmental.

Improper ergonomics leads to injuries, and other health problems.

How Ergonomics Relates to Technology

Physically:– Posture– Stretching– Exercise

Environmental– Uncluttered work area– Computer Placement– Monitor placement

Physical Ergonomics

Good Posture– Sit upright– Chin in– Shoulders relaxed– Wrists straight– Head upright– Feet flat

Stretches– Finger/wrist– Arm– Neck– Back

Exercises– Finger-flutter– Blink often

Environmental Ergonomics

Uncluttered workspace– Keep papers at monitor

level.– Easy access to mouse

and keyboard.– Room for chair

movement

Monitor Placement– Top of the screen

should be even with eye level.

– Near arms length away.

Possible Injuries

Repetitive-Stress Injuries– Carpal Tunnel

Muscle Related Injuries– Muscle Strains– Headaches– Eye Strain– Fatigue

Major Points

Maintain Good Posture! Change Work Positions Frequently! Rest Your Eyes – Look away and focus on a

distant object for several seconds! Stretch During Breaks! Don’t wait until you feel pain to stop an

activity!
