Study Notes
Keyboard Finger Placement
- Home Row: Keys are outlined in yellow on the diagram. The thumbs remain in the air or gently on keys below.
- Column Responsibility: Each finger is responsible for a vertical column of keys, sloping upwards to the left.
- Index Finger Responsibility: Both index fingers cover their home columns plus the ones next to them.
- Thumbs: Used for the space bar and potentially the “command” or “Windows” key.
- Left Pinky: Covers all keys left of its home column (shift, caps, tab, tilde, escape etc.).
- Right Pinky: Covers everything to the right of its home column.
- Hand Position: Mirrors the method developed for typewriters in the 1880s.
- Home Row Keys: ASDF (left hand) JKL; (right hand)
- Wrist Pads: Can be used but should not be used as a resting surface for the wrist, use for palms only.
Common Incorrect Typing Postures:
-
Wrist Extension: High keyboard causing wrist extension to hit keys.
- Fix: Lower seat, raise keyboard, maintain a straight wrist.
-
Closed Elbows and Shrugged Shoulders: Chair too low, keyboard too close.
- Fix: Raise seat, open elbows to 90-110 degrees, pull seat back, relax shoulders.
-
Arm Extension: Keyboard too far away.
- Fix: Bring keyboard closer, elbows at 110 degrees.
Ergonomic Typing Tips
- Type Lightly: Don’t pound keys, minimizes effort and fatigue.
- Rest Fingers on Home Keys: Each finger rests on a designated home row key.
Importance of Ergonomics
- Ergonomics: Prevents workplace injuries through proper posture and stretching.
- Common Injuries: Carpal Tunnel Syndrome and Tendinitis, caused by repetitive strain.
-
Prevention: Adjust workstations and habits:
- Seat: Feet flat, knees at 90 degrees, thighs parallel, 2-4 inches between seat and knees.
- Monitor: Top at eye level, 16-28 inches from nose, maintain upright posture.
- Keyboard and Mouse: Hands level with elbows or slightly lower, straight line from hands to forearms, relaxed shoulders, elbows close to sides.
- Ergonomic Keyboard: Helps protect wrists.
Quick Tips for Injury Prevention
- Avoid Pounding Keys: Use minimal force.
- Evaluate Posture: At home and at work.
- Take Breaks: Every 30 minutes, move around.
- Stretch Regularly: Before and after using a computer.
Computer Stretches
- Eyes: Close tightly, open widely, repeat several times. Look at an object 30 feet away.
- Hands: Spread fingers apart for 10 seconds, then clench fist, repeat.
- Neck: Slowly turn head to each side, hold for 10 seconds. Tilt head to each side, hold for 10 seconds.
- Shoulders: Slowly shrug shoulders in a circular motion (forward and backward). Spread arms and make slow circles (forward and backward).
