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
Collect this signal alongside session context, request metadata, and other independent indicators. 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.
