Mouse Speed & Acceleration

Move the mouse freely and at varying speeds inside the box for 3 seconds. We compute on-screen speed (px/sec) for every mousemove event and summarize the min, average, and max — plus a rough check for OS pointer acceleration by comparing your fastest movements to your slowest ones.

This is a simple heuristic, not a scientific acceleration curve fit — OS pointer acceleration, your own muscle control, and mousepad friction all affect the ratio.
