What the developers have to say:

Why Early Access?

“As a solo developer I understand it is important to gather feedback from other users before full release.
There are two main parts of the app that need work:
  • The Gesture System. The Stop Sign VR app runs alongside other SteamVR apps. It is important that it does not interfere with the operation of those other apps. Therefore, it's best to minimize the use of controller buttons for interaction. Gestures, without button presses, are better. This system is in development. The first gesture will be "holding both hands above your head for a second" to show all boxes, even when they are far away and faded out. What other gestures do you think would be useful?
  • The Dashboard Settings GUI is not yet finished. You can use the current dashboard settings page to turn on or off the main features of the app: Alert Mode, using boxes for alerts, using play area boundaries for alerts and using the Heads-Up Display for impacts out of view.
    There is a separate program for in-depth configuration of all other settings, and to add, remove and edit boxes. You can find this Settings Editor program in the Windows System Tray, next to the clock in the bottom right corner of the desktop.
If you have ideas on the above parts, please share!

Also, I would like feedback on the Impact Predictor. The Impact Predictor runs continuously, predicting where your controllers and headset will be a few moments from now. It will sound an alert if you will (probably) hit a box, a wall, the floor and/or the ceiling, based on your settings. You can change the prediction sensitivity using the Settings Editor mentioned above.

Do you use WMR, Oculus or Vive Cosmos controllers? Please let me know if the input bindings for those work well.

Finally, I intend to improve usability and clarity based on community feedback while still in Early Access.”

Approximately how long will this game be in Early Access?

“Stop Sign VR will remain in Early Access for a few months.”

How is the full version planned to differ from the Early Access version?

“The full version will have the same Impact Prediction functionality as the Early Access version has now, but the Gesture System and a user friendly Dashboard Settings GUI will be added. (See the first paragraph above.)
Other features may be added as well. If you have a good idea, don't hesitate to reach out!”

What is the current state of the Early Access version?

“The current version does a good job of impact prediction and it will definitely help you avoid hitting equipment, furniture, walls and ceiling.
For people that don't like the chaperone grid Stop Sign VR offers a substitute that can be less immersion breaking, while still offering protection (when compared to no guardian system at all).”

Will the game be priced differently during and after Early Access?

“The intention is to keep the same low price for the features described.
When extra functions are added, the price may rise.”

How are you planning on involving the Community in your development process?

“Feedback and input from the community is very welcome. Please see the first paragraph for the parts I'd like feedback on.
I intend to use Steam and Reddit as the central places for exchanging ideas and gathering feedback.
If you want to reach out by email, please do so at”

About This Game

Stop Sign VR helps you avoid hitting your computer monitor, TV, walls, ceiling, lamps, furniture and other objects in and around your VR play area.
While you are playing other games a prediction algorithm warns you of possible impacts using sound, images and haptic feedback.

Included is Boundary++, a new warning grid system that will show up when you approach your walls and ceiling. It works with native SteamVR headsets, Windows Mixed Reality (WMR) headsets, Oculus PC connected headsets and 'Mixed VR' sets (e.g. a WMR headset with Valve Index controllers).
Do you use a Mixed VR set and experience grey screens with seated games? This app fixes that problem!

Position (virtual) boxes around your valuable (real) equipment, such as TVs, ceiling fans, room lighting and so on.
Enter your ceiling height to get proximity alerts for the ceiling. If you want, it can also alert you before hitting the floor.

The boxes will fade out when you're not close. The fade-out and full-visibility distances can be configured for each box separately.
If you don't know where your boxes are, because they're faded out, press the System button and look around.


  • runs alongside other SteamVR games
  • works with all SteamVR (OpenVR) software, games, headsets, controllers and trackers
  • perfect for when you play Hack and Slash games or other games with melee weapons
  • Boundary++ also shows a grid on the ceiling
  • Boundary++ automatically imports the WMR Boundaries when using a Windows Mixed Reality headset
  • Boundary++ automatically imports the Oculus Guardian when using an Oculus PC headset
  • Boundary++ will not light up the whole play area, but will only show where you are actually near your boundaries
  • many configurable settings such as: alert distance, alert sound volume (or use no sound at all), turn off the default chaperone warning system, alerts for hitting ceiling or floor, etc.
  • use the separate Settings Editor program to edit all settings in Windows (not in VR); also use it to add, remove and edit boxes
  • predicts impacts of all your tracked devices: HMD, controllers and trackers
  • does not harm the performance of other VR software
  • the Stop Sign VR runtime is 100% coded in C++ and optimized to spend very little CPU/GPU cycles

The separate Settings Editor program is in the Windows System Tray, next to the clock in the bottom right corner of your desktop.

The alert sounds are spatialized by Steam Audio's HRTF-based binaural rendering so you will hear where the closest wall or object is, even if you can't see it.
