Robotic Mouse Path

Detection approach

Mouse path linearity is over 0.90. Human movement follows Fitts's Law with curved acceleration/deceleration arcs. Perfectly linear paths are a signature of programmatic mouse event injection (Selenium ActionChains, Puppeteer mouse.move).

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.
