Check shoulder level

This pose-only tool compares visible shoulder landmarks and flags uneven shoulder height that may come from mouse reach or leaning.

  • Left shoulder height
  • Right shoulder height
  • Shoulder delta
  • Mouse-reach next step

Your camera feed stays local. This checks visible posture signals only.

Shoulder symmetry is an ergonomic screen-work signal, not a diagnosis.

What this test measures

This check reads your shoulder delta from a short on-device camera scan and compares it against an evidence-based comfort range (< 6%). The model maps the joints involved and averages the angle so a single fidget doesn't skew your result.

How to read your result

Green means you're inside the healthy range. Amber means you're drifting and it's worth a small adjustment. Coral means the angle is past the comfort line for long enough to cause strain. Your number updates live, so you can watch a fix land in real time.

What to fix first

  • Adjust the one input driving the biggest signal — screen height, chair depth or input distance.
  • Re-run the test and watch the meter move before you change anything else.
  • Set a reminder so the corrected posture becomes the default, not the exception.

When to use WorkPose Pro

One test reads one signal. If you want this checked continuously — combined with posture, eye strain and fatigue, with live nudges and a progress history — that's what Pro does. It turns a one-off number into a habit that holds.

How this check works

  • The pose model runs in the browser and camera data stays on your device.
  • The check compares visible left and right shoulder landmarks.
  • Uneven shoulder height is treated as an adjustment prompt, especially for mouse-heavy work.

How to use your result

  • Shoulder level steady: your shoulder height looks balanced in this frame.
  • Shoulder tilt: bring mouse and keyboard closer, then relax both shoulders.
  • Repeated tilt: run the mouse shoulder or full posture scan to check the broader pattern.

Why shoulder symmetry matters

Desk workers often raise or reach one shoulder toward the mouse. A quick symmetry check makes that pattern visible.

How WorkPose Pro helps

Member sessions can watch whether shoulder imbalance returns during real work, not just during one check.

What to try

  • Move the mouse closer.
  • Relax both shoulders before typing.
  • Check chair and desk height if one shoulder keeps lifting.

Common questions

What is a shoulder symmetry check?

It compares visible left and right shoulder landmarks and shows whether one shoulder appears higher during desk work.

Can this explain shoulder pain?

No. It shows an ergonomic screen-work signal only. Use it to notice posture patterns and adjust your setup.

What should I do if one shoulder is higher?

Move the mouse and keyboard closer, relax both shoulders, and run a full posture scan if the pattern keeps returning.
