Hand posture check
Check visible finger curl and hand openness during keyboard or mouse 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 finger curl from a short on-device camera scan and compares it against an evidence-based comfort range (< 45%). 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 hand model check works
- The hand landmark model runs in your browser and camera data stays on your device.
- The check compares visible wrist, knuckle, and fingertip landmarks.
- Cramped-looking hand posture becomes an ergonomic reset prompt, not a health condition.
How to use your result
- Open: your visible hand posture looks relaxed enough for this short check.
- Cramped: open your fingers, relax your grip, and return to a lighter keyboard or mouse touch.
- Track: use WorkPose sessions when you want hand, wrist, posture, and fatigue signals together.
Why hand posture matters
A tight grip or curled fingers can happen during focused mouse and keyboard work. A quick camera check makes the pattern visible.
Best setup
- Keep one hand visible.
- Use your normal keyboard or mouse position.
- Avoid posing just for the scan.
Privacy and limits
The browser camera feed stays local with no upload. The tool checks visible landmarks only.
