Mouse trajectory
Records mousemoves and keystrokes; scores them on form submit.
What's measured on this page
- Mouse trajectory — every
mousemove is recorded; on submit the path length is compared to its bounding-box diagonal. A ratio < 1.005 means an essentially-straight jump.
- Keystroke cadence — intervals between key events are profiled. Identical intervals or zero-spread intervals look mechanical.
