How to point an arrow at the location of the oculus sensors (front setup)?

My VR experience is for rift. For people with 2 sonsors (front setup) I would like to have an arrow under the player which shows the position of the two sensors (to help them prevent oclusion). I’ve seen this in some VR titles and found it much less disturbing than the “TURN ARROUND” warning in Robo Recall. Is there a way to get the real world position of the sensors in blueprints, so that I can rotate my arrow in this direction?

Thanks for your help!
