This test visualizes the raw path of your mouse cursor to reveal sensor imperfections. It helps you identify 'Jitter' (erratic micro-movements when the mouse should be still or moving straight) and 'Angle Snapping' (software prediction that forces your cursor into straight lines, which is bad for muscle memory).
Jitter is often caused by a high DPI setting that exceeds the sensor's native capabilities (interpolation), a dirty sensor lens, or a poor-quality mouse pad surface. Wireless interference can also cause the cursor to 'stutter' or jump. If your cursor vibrates even when the mouse is stationary, that is sensor noise.
Move your mouse in smooth circles and diagonal lines. The drawn line should be smooth and follow your hand movement precisely. If the line looks jagged or 'stepped' like a staircase, you may have Angle Snapping enabled. If the line looks shaky or fuzzy despite smooth hand movement, your sensor has high jitter. A good sensor produces a clean, raw input line.
