Can you use a 2nd HTC Vive Headset with Controllers for Full Body Tracking?

Recommended Posts

Hi @ All!

Maybe im a little wrong here in a "developer" forum but the whole reddit vr community couldnt answere this question (or just didnt wanted to)

I tried some days now to get someone with the knowledge, even tried the vive support but they dont support modifications. Maybe this Forum can finaly help me to answere this discussion.

I posted this already in Vive https://www.reddit.com/r/Vive/comments/hz1wxr/can_you_use_a_2nd_htc_vive_headset_with/ and SteamVr https://www.reddit.com/r/SteamVR/comments/hzfxmr/can_you_use_a_2nd_htc_vive_headset_with/

Original Post:

"I currently have a 2nd Headset because it was cheaper to get a used Headset with controllers then buying a new controller to replace my broken one (some Button doesnt work anymore). Got it for 100€ because the base stations are missing.

Now i had the idea that maaaaybe i can use somehow the 2nd Headset to track the 3 missing trackingpoints for fullbody.

I mean its possible to use controllers as trackers so maybe its even possible to use a 2nd Headset for that. Right?"

 

Points we already know from the Reddit discussion:

- We can use the HMD to convert 2 Controllers to Trackers without USB Dongles

- Technically it should be possible to make the HMD to a Tracker/Reciever but noone tried it before

- We can at least use 3 Controllers with one headset if we use a USB cabel on the free USB slot on the headset to connect the 3th (or more) Controller.

 

I personaly dont have coding skills to find it out myself but maybe this forum can help me and everyone with an old, not used anymore htc vive headset.

 

Thx in advance for any answere you can give me.

Edit:

Forgot to mention some things.

For a better understanding what we / i want to achieve.

The Main idea is to mount the headset itself on the hip as a Tracker and pair the converted Controllers (now also trackers) to it.

Sure it would be easier to buy a 3th Controller and just connect it with usb to the headset on the head but that also would mean i need a 3th Controller (5 in total).

And before i buy a controller for that i also just could buy a tracker.

The Main reason behind it is simple. Everyone that somehow have a vive thats not used anymore could go full body without spending any money.

That would help the community and the market for full body games. Most people dont go full body because its just too expensiv.

More player for full body = possible more games for it because of demand.

Sure thats maybe not such a big deal but it would be awesome for alot of people.

  • You can attempt to mod the two controllers into tracker-type devices via this guide using a Steam controller dongle per controller as the way to transmit the IO. As with all mods, you can brick the device if you mess up the firmware too badly. It's clunky as hell but it can work. Not as good of a UX as the purpose built trackers though.

 

  • I'm not aware of any firmware mods you can apply to the HMD to get it to act as a tracker. Beyond the fact that I don't think there's a built out community solution, there are some pretty clear practicality concerns here for instance the fact that you'd still need to use HMD tether to supply power to the main board and the device itself is huge. I don't think this is a super feasible option and the amount of time and effort you'd spend trying to get something like this to work would be far more than the cost of just purchasing a Vive Tracker in terms of your time and effort.

Having extensively used trackers - I think the controller mods are more than they're worth generally. If you're doing some serious full body stuff - the size and weight of the tracked device really matters and being able to use something like a trackstrap is a game changer in terms of ease of use.

Thx for the Reply!

Does the controller solution only work with a dongle or can the 2nd HMD be used to pair and connect them?

I know its not the most comfortable solution but thats the hardware i have laying around and im not a dancer.  In the current state of the discussion its more an experiment and "crazy" fullbody solution for people that somehow got to the point where they have a old HTC Vive laying around. Maybe because of upgrading to vive pro or maybe because it was cheaper to get a set then buying a new controller like in my case.

Its like with everything that people want to try but are scared with the money they would need. They want to try it with what they have even if it not as good as the real deal.

I myself made something even crazier before i got my vive. I designed and 3d printed my own VR Headset with lenses of an old samsung gear (got it as a gift but dont had the right phone for it). I even designed it with ajustable lens to phone and eye to eye distance.

It was ugly, heavy, uncomfortable, nausea inducing and a gigantic waste of time BUT! It was my first real VR Expirience and i was able to play some time in VRChat and even had hands (2 older phones).

That was the reason why i got a used HTC Vive. I was aware that my experiment wasnt that great of an expirience but it made me want the real deal.

And the reason why im here and on reddit with my "crazy" idea of a HTC Vive Headset fullbody is plain and simply because i cant do it myself. I have zero programing skills and it would take me ages before i could finish this experiment. I just hope there is some good soul out there that could look into that and maybe help me with it or at least give me a clear "yea we can do it if we change X and Y" or "Nope sry isnt possible because of X and Y"
