Installation

pip install python-ovrsdk

Use

importtimefromovrsdkimport*ovr_Initialize()
hmd=ovrHmd_Create(0)
hmdDesc=ovrHmdDesc()
ovrHmd_GetDesc(hmd, byref(hmdDesc))
printhmdDesc.ProductNameovrHmd_StartSensor( \
hmd,
ovrSensorCap_Orientation|ovrSensorCap_YawCorrection,
0
)
whileTrue:
ss=ovrHmd_GetSensorState(hmd, ovr_GetTimeInSeconds())
pose=ss.Predicted.Poseprint"%10f %10f %10f %10f"% ( \
pose.Orientation.w,
pose.Orientation.x,
pose.Orientation.y,
pose.Orientation.z
)
time.sleep(0.016)
