start
Starts providing motion tracking data using the specified MotionTrackingStartInfo.
You can request the exact number of motion trackers via MotionTrackingStartInfo.requestDeviceCount, and receive the result through addRequestCompleteListener.
Note that the user may not connect the exact requested number of trackers. You should check the request result via TrackerRequestCompleteListener.onRequestComplete.
After starting, you can get the latest data from latestData, register a DataListener using addListener to receive data, or get data from dataFlow.
If the current type of data is not available, StartResult.PENDING will be returned. Data provision will automatically start once all requirements are satisfied.
Return
StartResult.SUCCESS if motion tracking starts successfully, or StartResult.PENDING if the current type of data is not supported.
Parameters
The configuration for starting motion tracking.
