# Headset Calibration Tips for the Wearer

With the headset on, the AR 51 avatar lines up with your body **automatically** — no button, no poses. Here's how to get a clean alignment.

## Steps

1. **Put on the headset.**
2. **Step into the capture area**, where the cameras can see you.
3. **Stand still for a second**, looking straight ahead.
4. **Walk a few normal steps.**

Done — it stays aligned while you move. After a headset recenter it lines up again on its own.

## Do's and don'ts

![AR 51 headset calibration dos and donts: stand fully visible to the cameras, stand still and look straight ahead at the start, walk a few relaxed steps, keep your head uncovered, use a well-lit room, and move and turn your head so the system knows which person is you — resulting in an avatar lined up under your body](./img/headset-calibration-guide.webp)

*Good technique (✅) and the common mistakes to avoid (❌).*

**Do**

- **Stand inside the capture area**, fully visible to the cameras.
- **At the start, stand still for a second and look straight ahead.**
- **Walk a few relaxed steps** in different directions — a little movement makes it precise.
- **Keep your head uncovered** and visible to the cameras.
- **Use a well-lit room** so the headset tracks reliably.
- **If other people are present, walk and turn your head a little** so the system knows which person is you.

**Don't**

- Stand at the edge, behind an object, or half out of view.
- Spin around or look at the floor or ceiling right at the start.
- Stand frozen in one spot — it needs a little movement to lock in.
- Wear a hood or big hat that hides your head from the cameras.
- Work in a dark room, or with a headset that keeps losing tracking.
- Stand still side by side with another person at the start — the system can't tell which one is wearing the headset.

## Check it worked

- **Good:** look down — your avatar's body and feet are right under you. When you walk it stays with you, and small corrections are smooth.
- **Needs a fix:** the avatar is shifted, rotated or floating, or the room keeps slowly turning. **Fix:** stand still for a second looking ahead, then walk a few steps.
