VR Playtest Safety and Comfort Protocol

A VR playtest protocol is a written set of steps that keeps testers safe and comfortable before, during and after a session. It covers the physical space, the people watching, how often testers rest, when a session stops for motion sickness, how consent works and how headsets are cleaned. Write it down, share it with every tester and follow it even when the session feels relaxed.

Why does a VR playtest need a written protocol?

Headsets block the view of the real room. A tester who is fully immersed can walk into a wall, trip on a cable or swing an arm into a person without noticing. Even a calm tester can feel sick or disoriented after a few minutes, and many people do not say so until they feel worse.

A written protocol takes the pressure off everyone. Testers know what will happen. Staff know their roles. Nobody has to decide in the moment whether a problem is serious enough to stop.

What should you check before the session starts?

Set the room up before the first tester arrives, and check it again before each new person.

• Clear the play area of furniture, pets, loose rugs and cables.
• Set the guardian or boundary to a generous size, with extra margin for fast movement.
• Confirm the headset is charged and the cables are routed away from the tester's feet.
• Keep water and a chair within easy reach.
• Put a sign near the door that says the session is in progress.

If you are not sure the boundary is set right, walk the edges yourself before any tester arrives.

Who needs to be in the room?

A typical protocol has at least two people: the tester and a spotter. The spotter is not there to play or to take notes on the game. They stay within arm's reach of the tester, watch the play area and step in when needed.

Give the spotter a short script:

1. Watch the tester's feet and head, not the screen.
2. Stop the session if the tester moves toward a boundary or a hazard.
3. Call a pause if the tester stops talking, grips the chair or says they feel strange.
4. Keep a log of breaks and any incidents.

Rotate spotters on long days so no one gets tired and distracted.

How should you handle breaks?

Plan breaks into the session. A tester who is waiting for a break often stays too long because they do not want to interrupt. Use a timer or a visible schedule.

Moment	Action
Start of session	Explain the stop rule and the break schedule
Every task or level	Offer a short pause, even if the tester feels fine
Any sign of discomfort	Stop, remove the headset and give a longer break
End of session	Check in and ask how they feel before they leave

Make it normal for testers to take off the headset. Say it out loud at the start.

What is the motion sickness stop rule?

A stop rule is a clear instruction that tells everyone when to end the session. Keep it simple and absolute:

• Anyone can say stop at any time, for any reason.
• The session pauses immediately when someone reports nausea, dizziness, sweating, pale skin or a headache.
• Testers do not need to justify a stop.
• The tester does not return to the same build until they have rested.

Do not treat a stop as a failure of the tester. A stop is information about the game. If many testers stop at the same point, the comfort settings or the movement design need attention.

Keep the warning signs from the stop rule on the station wall, so the spotter can check them without searching for them.

Consent, privacy and aftercare

Tell testers what you will record and what you will do with the notes before they put on the headset. Get written consent for any video, screen capture or audio. Let them change their mind before the session ends.

After the session, check in with each tester. Ask how they feel, and give them the name of someone to contact if symptoms continue. Tell them to avoid driving or other precise tasks until they feel normal.

Clean the hardware between testers

Shared headsets need cleaning between every session. Wipe the face cushion and the lenses with the manufacturer's recommended wipes, replace or clean the face cover and let the headset dry before the next tester uses it. Keep a supply of replacement covers on hand.

Put the protocol on one page

Write the whole protocol on one page and keep a copy at the station. Include the boundary checklist, the spotter script, the break schedule, the stop rule, the consent wording and the cleaning steps. Review it after each session and update it when something goes wrong. The aim is not to make playtests stiff. It is to make the session boring in the right way: nothing unexpected happens, everyone knows what to do, and the testers can focus on the game.
