Xerxes Posture Monitor

Desk posture alerts that reach you in any tab. Works with the Xerxes dashboard. No data leaves your machine.

The alerting half of Xerxes. The dashboard watches your posture through the webcam; this extension is what makes an alert reach you when you have already tabbed away to something else. Nothing is measured here. No camera access, no page content, no network calls. This extension receives a state signal from the dashboard tab and decides whether that state is worth interrupting a human being over.
