left right or falling down or up . Therefore humans can detect alignment and rotation around the the same X Y and Z axes as the phone. Now imagine someone now rotates you 90 degrees on the roundabout so that you are now facing East. You are.. This allows us to ascertain which direction we are facing. The same is true with our phone.
