Movement In VR Vive Using collision boxes

Hello, I seem to be in a bind, I’m trying to make a way for the player to move without using teleport, by using a circular line graph image outlined on the floor so the inner ring is for free walk and the outer ring would act like a d pad, or dance dance revolution. My problem is i don’t know how to make it so the player and camera move in that fashion nor do i know how to make the collision boxes and the image move simultaneously with the character and do a check to stop walking when the player goes back into the center.
