Mimic Vive Controller with Vive Tracker 1.0 (but GetTrackedDeviceClass reports GenericTracker)

[mmorselli]

My goal is to emulate 100% of a Vive Controller using a Vive Tracker (1.0). I know Role Changer and I know how to modify the .json from the console, I'm comfortable with this, but all my attempts do not lead to the desired result.

Although some applications recognize the tracker as a controller (when the role is a controller), for SteamVR it 's always a tracker

this, I guess, is due to the fact that the device class is still read as a tracker

vr::VRSystem()->GetTrackedDeviceClass(id)

returns TrackedDeviceClass_GenericTracker

and not controller

Some application, as Beat Saber, doesn't recognize controllers if DeviceClass is incorrect

 

how can I modify the .json, or what other operation can I do, so that it becomes 100% a controller?

@mmorselli Are you referring to the Role Change tool we used to make available on this forum? If so, that's the only real way to fully get SteamVR to think a tracker is a controller - that tool modifies the watchman firmware on the device to change what device type it reports back to SteamVR.

yes, I tried with VIVETrackerChanger_1.0, but vr::VRSystem()->GetTrackedDeviceClass(id) allways reports TrackedDeviceClass_GenericTracker, and SteamVR still pair those as trackers, not as controller

Changing role is useful because the pogo pin buttons get back to work and many apps recognize them as controllers, but not all, Beat Saber is one of them.

Old matzman OpenVR Input Emulator has a command line tool that can list all device properties, this is how my tracker looks... but It's still recognized as tracker for Device Class

@mmorselli,

Please don't use the Role Changer, that was retired for good reason, the proper way when using SteamVR is to map the input binding "as hand". However you can only use 2 devices  as "hands" at a given time (i.e. use of controller equivalent input via the tracker's pins).
