Check jaw and facial reset signals

This tool watches jaw-open blendshape signals alongside blink behavior and head drops. It is framed as a relaxation prompt, not a jaw diagnosis.

  • Jaw-open movement
  • Yawn-like signals
  • Blink rhythm
  • Head-drop pairing

Jaw signals are noisy and context-dependent. Use this as a gentle reset prompt, not a diagnosis of jaw tension or TMJ.

What this test measures

This check reads your jaw signal from a short on-device camera scan and compares it against an evidence-based comfort range (< 15). 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 facial check works

  • The facial model reads jaw-open movement from face blendshapes.
  • WorkPose treats repeated yawn-like jaw opening as one possible reset signal, especially when paired with eye closure or head drops.
  • The page avoids medical claims and keeps the camera stream in the browser.

How to use your result

  • Jaw relaxation pattern: repeated jaw-open or yawn-like signals can be a prompt to unclench, breathe, and reset.
  • Jaw signal alone: do not overread one movement; look for repeated patterns or pairing with eye strain.
  • Repeated jaw plus head drops: take a short reset before continuing the work block.

Why this is a relaxation check

Desk workers often hold facial tension without noticing. This page turns jaw movement into a simple awareness prompt while avoiding medical claims.

How to use the result

If the signal repeats, relax your jaw, look away from the screen, and reset your posture. If discomfort is persistent, use appropriate professional care rather than relying on this tool.

How WorkPose Pro helps

WorkPose sessions can combine jaw, blink, fatigue, and posture signals into more useful reset prompts during the workday.
