What is the recommended distance between the user's eyes and a computer monitor?
Answer: 20–40 inches
An arm's length distance of approximately 20–40 inches (50–100 cm) reduces eye strain and allows comfortable focal adjustment.
Where should the top of a computer monitor be positioned relative to eye level?
Answer: At or slightly below eye level
Placing the monitor top at or slightly below eye level allows the eyes to gaze slightly downward, reducing neck extension and eye fatigue.
The recommended elbow angle when typing at a keyboard is approximately:
Answer: 90–110°
Elbows bent at 90–110° with upper arms close to the body and wrists neutral minimizes static shoulder and forearm loading.
Which keyboard feature is most effective at reducing ulnar deviation during typing?
Answer: Split ergonomic design
Split keyboards angle each half outward, allowing the wrists to remain in a more neutral alignment and reducing ulnar deviation.
What is the primary ergonomic benefit of a document holder placed next to a monitor?
Answer: Minimizes neck rotation and repetitive head movement
A document holder positioned adjacent to the monitor at the same height and distance prevents repetitive neck rotation between paper and screen.
Keyboard trays that slope negatively (front edge higher than back) are intended to promote:
Answer: Neutral to slight wrist extension
A negative tilt positions the keyboard so fingers reach forward and slightly downward, promoting a neutral or mildly extended wrist aligned with the forearm.
