Mouse Drift Test · At a glance
Quick answer: Observe cursor movement while the mouse is resting. Small motion can come from surface vibration, sensor noise or another pointing device.

Detailed guide
How to use this tool
- Start the tracker and leave the mouse untouched on a stable surface.
- Watch for new coordinates after your hand has stopped moving.
Input
Movement inside the test surface
Browser requirement
Pointer coordinates after OS transforms
Processing

How it works and what the result means
Coordinates are CSS pixels after operating-system pointer settings. Speed is browser-visible cursor speed. They do not directly expose raw sensor counts, DPI, physical acceleration or lift-off distance.
Reading the result
Small motion can come from surface vibration, sensor noise or another pointing device. The trace alone does not identify the source.
What to check next
Lift your hand away, disconnect other pointers and repeat on a different clean surface. Keep fans or vibrating objects away from the desk.
For drift, leave the mouse still. For jitter, draw a slow straight line. For lift-off testing, add measured spacers yourself and observe when movement stops being reported.
Frequently asked questions
Can a web page identify which device caused movement?
Ordinary pointer coordinates may combine input sources. The page cannot reliably attribute each movement to one physical sensor.
How do I start the Mouse Drift Test?
Start the tracker and move the cursor inside the test surface. Use the trace and distance statistics to compare different movements.
Does this tool require a download or an account?
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Why can two attempts give different results?
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
