Mouse shoulder balance check
Check whether mouse reach is lifting one shoulder during desk work. Works with your phone camera, laptop camera, or webcam. It runs entirely in your browser and the camera feed never leaves your device.
Prop your phone at desk height for front checks, or turn it sideways for side-view posture scans. Same test, same URL, no app.
Open phone linkWhat this test measures
This check reads your shoulder lift 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 left and right shoulder height, then looks for visible wrist reach when hands are in frame.
- A raised-shoulder result is framed as a mouse placement prompt for desk ergonomics.
How to use your result
- Balanced: shoulder height and visible reach look controlled in this frame.
- Mouse-side lift: bring the mouse closer, lower the shoulder, and keep the elbow nearer your side.
- Hands out of view: use the shoulder result carefully, or adjust the camera so wrists are visible.
Why mouse reach changes shoulder balance
A far-set mouse can make one shoulder lift or reach forward during repeated pointer work. This check makes that visible from the front camera.
Best setup for the check
- Keep both shoulders visible.
- Include wrists if possible.
- Use your normal mouse position instead of posing.
What to try next
Move the mouse closer to the keyboard, relax both shoulders, and re-run the check to see whether the shoulder-lift signal changes.
Common questions
What does mouse shoulder balance mean?
It means the tool compares visible shoulder height and wrist reach while you use a mouse or trackpad.
Do my hands need to be visible?
The shoulder comparison still works with shoulders visible, but wrist landmarks make the reach signal more useful.
What should I change first?
Bring the mouse closer, keep the elbow near your side, and relax the shoulder before continuing.
