Robotic Mouse Velocity

Detection approach

Mouse velocity variance is under 0.01. Real human hand motion exhibits high variance due to muscle tremor, target-acceleration curves, and micro-corrections. A near-zero variance indicates constant-speed robotic movement.

How this helps detect bots

This signal is assessed with other independent session, browser, and network evidence. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.

Legitimate traffic to consider

Drawing stylus pens, eye-trackers, or assistive cursor devices.
