[VBS & PC VR ] How to get controller / wrist tracker tracking result status on OpenVR

[Vivi Wu]

 If you'd like to know whether your controller / wrist tracker is in 6Dof or 3Dof status, please follow the guidelines below.

 

Required:

·           VIVE Business Streaming version : 1.10.5 or later.

·           Focus 3 – FOTA version : 5.0.999.676 or later

 

Check OpenVR API to get status:

·           IVRSystem::GetDeviceToAbsoluteTrackingPose

·           IVRSystem::GetControllerStateWithPose

Both API can get TrackedDevicePose_t of devices with parameter-“ETrackingResult”, which is the tracking status of device.

·        6Dof = TrackingResult_Running_OK

·        3Dof = TrackingResult_Fallback_RotationOnly

 

The index of each device:

index	device
0	HMD
1	Right controller
2	Left controller
3	Right wrist tracker
4	Left wrist tracker

To access the target device and retrieve its status, please generate a large enough array and call the appropriate API. Use the index specified in the above table to obtain the status of the target device.

Sample code:

vr::IVRSystem * pvr = vr::VR_Init(&eError, vr::VRApplication_Utility); TrackedDevicePose_t result[5]; pvr->GetDeviceToAbsoluteTrackingPose(vr::TrackingUniverseStanding, 0, &result, 5); result[1].eTrackingResult; // right controller tracking result result[2].eTrackingResult; // left controller tracking result result[3].eTrackingResult; // right wrist tracker tracking result result[4].eTrackingResult; // left wrist tracker tracking result
