Help / For whoever owns the headsets
Headset setup and cart operations
The goal is simple: every headset has every lesson on disk before students arrive, so class itself needs no network at all.
Supported headsets: Quest 3, Quest 3S, and Quest Pro.
Installing Vantura
Vantura installs from the Meta Horizon Store like any other app. During the beta, accept the email invitation first, then find Vantura in your library and install it. No cables and no sideloading.
Pairing a headset
- Open Vantura. It shows a six character code.
- On a phone or laptop, sign in here and open Pair headset.
- Type the code. The headset signs itself in within a few seconds.
- If the account is not yet enrolled in the class, enter the class join code once.
Headsets stay signed in between sessions, including across reboots. You pair once.
Cart accounts
For a shared cart, pair every headset to one department account that is enrolled in the class. Students then pick up any headset and start watching, with nothing to log in to. This is the pattern we recommend for lab carts.
Downloads belong to the device rather than the account. If you do switch accounts later, the headset does not re-download lessons that both accounts can see.
The routine before class, about five minutes hands on
- Put each headset on power and on the lab Wi-Fi.
- Put it on and open Vantura. The class library appears and anything new starts downloading. Each lesson shows Downloading with a percentage, then Downloaded.
- Do not set the headset down while it is still downloading. See the note below.
- Confirm from your desk with no headset required: your class, then the Headsetspanel. Every device should read “Ready, all N videos” with a recent check-in time.
- Done. Wi-Fi can drop or be saturated during class. Playback is entirely local.
The proximity sensor, and the piece of tape
Quest 3 and Quest Pro have a sensor between the lenses that decides you have taken the headset off. When it triggers, the headset sleeps, and sleeping pauses downloads.
We measured this: a headset set down goes to sleep roughly 15 seconds later, even in the middle of playing a video. Vantura holds the display awake against the ordinary inactivity timer, but it cannot override the sensor, and it should not try to.
So while prepping several headsets, either put a small piece of tape over that sensor and remove it when you are finished, or come back to each headset every few minutes until every badge reads Downloaded.
The Quest 3S has no proximity sensor, so this does not apply to it. Set it down and it keeps downloading.
How long it takes
Measured on home Wi-Fi in July 2026, with real files. Re-measure on your campus network, because that is the variable that matters.
| What | Time |
|---|---|
| App open to downloads starting | about 5 seconds |
| Sustained speed per headset | about 50 MB/s, roughly 400 Mbps |
| One 8K clip, 345 MB, measured | about 7 seconds |
| A 5.7K lesson, about 3.4 GB, projected | 1 to 1.5 minutes |
| An 8K lesson, about 6.8 GB, projected | 2.5 to 3 minutes |
| Reopening with nothing new | seconds, no downloads |
Projections scale with your Wi-Fi. If campus gives each headset a quarter of that speed, multiply by four. Downloads run one at a time within a headset, and headsets download independently of each other.
One caveat worth stating plainly: our timed run prepped headsets one after the other, so the claim that a whole cart syncs in parallel is reasonable but not yet measured. If you prep a cart, we would genuinely like to know what you see.
What students can do in the headset
- Pick a lesson from the menu, using hands alone. Controllers are supported but not needed.
- Play and pause.
- Recenter, which snaps the video's forward direction to wherever they are looking. Useful when someone is seated at an angle to how the camera was set up.
- Turn left and right in 15 degree steps.
Turning is left and right only, by design. Tilting a 360 video takes the horizon off level, and that mismatch is a common cause of discomfort in a headset. Recentering resets per lesson.
Troubleshooting
- A badge is stuck on Cloud. That headset has not refreshed its catalog since the lesson was uploaded. Choose Refresh on the home screen, or reopen the app.
- “Offline, showing downloaded videos.” The headset lost Wi-Fi. Everything already downloaded still plays normally. Reconnect to pick up anything new.
- A download was interrupted by sleep or a Wi-Fi drop. It resumes where it stopped the next time the app is open on Wi-Fi. Nothing to redo.
- Storage is full. Least-recently-watched lessons are removed automatically to make room. Unpublishing lessons you are done teaching is the cleaner fix.
- The headset is back at the pairing screen. It needs to be paired again. This should be rare, and if it happens more than once on the same device we want to hear about it.
- Audio kept playing after someone took the headset off. Expected for about 15 seconds, then it pauses when the headset sleeps. That delay is set in Horizon OS under Settings, Power, Auto Sleep.
Signing out
Sign out is on the headset home screen and asks for a second press to confirm. Use it only when you actually intend to hand the headset to a different account, because signing out means pairing that headset again.
