Before you drop in

TRACER is part of a student research project on telling human mouse input apart from automated "cheat" input. Each session is a one-minute target-shooting round.

TRACER needs a desktop or laptop with a mouse. Phones and tablets can't take part.

Recorded

Mouse movement and clicks inside this page only, with timestamps, plus target positions.
Your settings: game, in-game sensitivity and FOV, mouse DPI and polling rate if you enter them.
Coarse technical details: browser family, pixel ratio, input sample rate, timer precision.
Optional: your FPS experience and input device.

Never recorded

Your name, email, accounts or a full browser fingerprint.
Your IP address is never saved with your data. (The hosting provider sees it in transit, as with any website.)
Anything outside this page: keyboard, other apps, other games.

Your rights

You're identified only by a random participant ID. Note it if you may want your data deleted later.
You review every round and choose to save or discard it.
Stop any time with Esc. Aborted rounds are never saved.
Saved rounds are stored on a private research server that only the researcher can access.
Anonymised data may appear in a public portfolio/report.

Hip-fire sensitivity. The view turns at your game's rate and is drawn with its FOV, so every flick takes the same hand movement as in-game.
