A:Answer To make it clear, you do not need the straps or extra trackers (sold separately) to make your Rift S function like a normal VR headset. The straps in this bundle are just to make it easier to use Full body tracking. If you want full body tracking, you need at least 1 additional base station and the 3 vive trackers (tech only 2 trackers needed for feet, but the one on your hip GREATLY improves movement), all of this is sold separately. there is another way to simulate full body tracking with a xbox connect camera, but that is a diffrent story.
