Cosmos with Index controllers ?

Recommended Posts

The Cosmos seems to get bashed a lot in the VR community for its bad hand/controller tracking. There’s not much negativity about the HMD and head tracking. The HMD is not perfect but all the others have issues/niggles too.

Could Cosmos owners (that don’t want to sell their kit and buy an alternative VR system) simply purchase the Valve Index controllers, base stations and setup the hand tracking only in SteamVR. Leaving the Cosmos standard?

Making the External Faceplate Addon an option. Or would the faceplate be REQUIRED in order to use the Index kit?

Hey @viniebenet3,

Great question! The Faceplate addon is required in order to use any steamvr related tracking devices such as the Index and Vive/Pro controllers.

I understand what you're proposing, but it wouldn't work 😞 The Index controller is using external tracking (base stations) and therefore, the headset would also require the exact same tracking system as the controllers so they can accurately share the same positional data.

In practicality - using the External Tracking plate is the only robust way to use knuckles with Cosmos. The ET faceplate is a requirement to use knuckles with Cosmos.

There are tools like OpenVR-SpaceCalibrator which can theoretically be used to hybridize different tracking systems into SteamVR using a bunch of math. The unfortunate reality is that the tool is a single-person open source project and that SteamVR has been updating like crazy. In the last year SteamVR alone pushed out over 300 beta releases and a number of major releases whereas the calibrator tool hasn't been updated in 13 months. Release 1.7.x specifically broke that tool in some instances. It'd basically be a full time job to keep up to date with SteamVR's update cycle and there's always the chance that updates could completely nuke tools like this, even if you stay on top of it.

You'd also need to figure out how to get knuckles to talk to to your PC. I'm not sure how'd you'd do this beyond hacking Vive tracker/Steam controller bluetooth dongles.

If you try to "hack" knuckles to work with Cosmos without the ET faceplate - it's going to likely be way more trouble than it's worth and will likely not be stable if you're able to get it working at all.
