After reading the SDK reference document, I find this method sixenseAutoEnableHemisphereTracking which I can alternatively use to perform Hemisphere Tracking, so the system can determine which point is in true position where the controller is held by the user.

However, this description is confusing me since I don't know where is the correct place to call this method.
To use this call to enable hemisphere tracking, prompt the user to point the controller at the base unit and then make this function call.

Is it correct to call this method right after the first time the user presses the trigger in the proper position relative to the base unit? Then, the true position of the controller (not mirror one) will be determined and x, y and z position and rotation values can be what I expect.

Thanks a lot for your help.
