Ergonomics, Equipment, and Training Environment Design
This domain tests whether you can link reported symptoms to workstation and equipment variables, and design a team facility that supports performance rather than just looking professional.
Workstation rules of thumb
- Monitor top edge at or slightly below eye level; viewing distance around arm's length, roughly 50-75 centimetres.
- Elbows near 90-100 degrees, forearms supported, wrists neutral rather than extended.
- Chair with lumbar support, feet flat, desk height allowing relaxed shoulders.
- Keyboard and mouse close enough that the shoulder does not protract; mouse sized to the player's grip style (palm, claw, fingertip).
- Ambient lighting with no glare on the screen; avoid a bright window behind the monitor.
- Room temperature around 20-22 degrees Celsius and moderate humidity; airflow matters during long sessions.
Equipment variables
- effective DPI equals mouse DPI multiplied by in-game sensitivity; players compare sensitivity in these terms, and changing either changes feel.
- Mouse weight, shape, and skates affect fatigue and precision.
- Keyboard switch actuation force matters for finger fatigue over long sessions.
- Monitor refresh rate and stable frame rate affect perceived reaction time; frame drops are a performance confound.
- Network latency and jitter are performance variables and should be logged during scrims.
Facility design
Separate scrim rooms from rest areas, control acoustics, provide break space away from screens, and standardise player stations so that substitutions do not change hardware feel.
Worked example
A player reports neck ache and blurred vision in the second hour. Reasoning: blurred vision plus neck pain points to viewing distance and monitor height rather than wrist mechanics. The monitor is 90 centimetres away with its top above eye level, forcing chin-up posture and sustained near-far accommodation. Move the monitor to roughly arm's length, lower the top edge to eye level, add a slight recline to the chair back, and schedule microbreaks with distance viewing. Recheck in two weeks before considering equipment purchase.
Traps that cost marks
- Prescribing one ideal posture for everyone; individual anthropometry varies.
- Assuming expensive peripherals fix pain caused by load and posture.
- Confusing DPI with effective DPI.
- Designing a facility with no break space away from screens.
