ISSUE WITH HTC VIVE/VIVE PRO MULTI-USER ENVIRONMENT SETUP

Recommended Posts

Hello Everyone!

We are having issue trying to use the Vive headsets in a multi-user environment. We have been doing it succesfully in the past, but in our experience we have noticed
that things get messed up whenever there are updates to SteamVR, firmware upgrades to headset, controllers, trackers etc. 

The HTC documentation is conflicting and unclear. For example, on their official website, it is stated that Vive/Vive Pro headsets can be used together in a multi-user
environment and the only thing mentioned is that 2 base stations are required for a 5x5m area and 4 base stations for 10x10m area. 

Link: https://www.vive.com/us/support/wireless-adapter/category_howto/multiuser-environment-examples.html

This is conflicting with their Vive Pro documentation guide which states that only Vive pro headsets are recommended for the multi-user environment and base station
V2.0 would be required.

For us, we have been unable to use the HTC Vive headsets in a multi-user environment as one headset keeps showing a green screen (no display output).
By far, we have tested the following scenarios using official HTC Vive products:

PC1 and PC2 are both built to the same specs:
Motherboard: ASUS TUF H370 Pro Gaming
Processor: Intel Core i5-9400f
RAM: Corsair Vengeance 8GB DDR4 2400Mhz
GPU: Nvidia Geforce RTX 2060 
Storage: WD Green 240GB SATA III 6Gb/s 

Scenario 1:

Base Stations: 2x V1.0
PC1: HTC Vive with HTC Wireless kit 
PC2: HTC Vive Pro with HTC Wireless kit
Result: Vive wireless= green screen, Vive Pro wireless= working.

Scenario 2:
Base Stations: 2x V1.0
PC1: HTC Vive Pro with HTC Wireless kit 
PC2: HTC Vive with HTC Wireless kit
Result: Vive wireless= green screen, Vive Pro wireless= working.

Scenario 3:
Base Stations: 2x V1.0
PC1: HTC Vive wired 
PC2: HTC Vive Pro with HTC Wireless kit
Result: Vive wired= green screen, Vive Pro wireless= working.

CHANGING BASE STATIONS TO V2.0

Scenario 1:
Base Stations: 2x V2.0
PC1: HTC Vive Pro wired 
PC2: HTC Vive Pro with HTC Wireless kit
Result: Vive pro wired= green screen, Vive Pro wireless= working.

The play are has sufficient space, approximately 6x4m and each headset has more than 2x2m spacing.

Everything has been set according to the guidelines by HTC (We have been using Vive headsets for 2 years now so we can be considered as experienced users)

We have spent thousands of dollars purchasing premium HTV Vive products, we have multiple headsets, base stations, controllers, trackers etc. but our problem is
not being resolved and the HTC support is unable to understand the problem. They do not have any solution other than to refer us to unhelpful documentation
which is not only conflicting but also we have tried all the scenarios and gone through everything many times.

Our activity is already getting very late and we have no help from HTC official support and our issue resolved. Can anyone suggest any solution to our problem?
We would be really grateful if some can help. Thanks!

@JohnMarstonEvolve -

  • I've PM'ed you the email contact for the enterprise support team - they're the team best equipped to help you break this down.
  • Multi-user usage is technically possible using base-station 1.0 but the use-case is very limited and it's not recommended for safety and practicality reasons:
    • You can only use 1 pair of 1.0 base-stations in a room/line-of-sight.
      • You need to physically isolate 1.0 base-station pairs otherwise conflicts arise
    • You can only cover about 5 meters diagonally with 1.0 stations
    • It's not super safe to fit more than 1 or 2 users in the tracking volume provided by 1.0 base-stations. The risk of people running into each other and making physical contact with each other is very high at the play volumes supported by
  • Using 2.0 is overall far far better for multi-user because:
    • Larger tracked volumes = bigger play-volumes and larger buffers between players
    • Support for multiple base-stations within the same room without conflicts
      • No need for physical isolation between base-station pairs
    • You can use anywhere between 1-4 stations to track each HMD - it's just more flexible overall
    • The wider horizontal FOV enables more mounting positions.
  • You cannot use 1.0 and 2.0 tracking in the same room/line-of-sight as each other without physical isolation
  • 1.0 base-stations work with Vive and Vive Pro.
  • 2.0 stations strictly work with Vive Pro and other 2.0 enabled devices (tracker 2018, Vive Pro controllers, Valve Index, Ect...)
  • Vive 1.0 gear is either the discrete or the TS3633 sensor type in the matrix below. Vive Pro gear is generally on the TS4231 and newer revisions.
  • Scenario 1 should work if deployed correctly - this doesn't make sense.
  • Scenario 2 should also work if deployed correctly due to use of 1.0 stations
  • Scenario 3 should also work if deployed correctly
  • Scenario B1 should definitely work.

I think something else is going on here.
