I was curious how VR headsets can track the headset's position in a room so I read this article https://en.wikipedia.org/wiki/Pose_tracking. I learned that have two views, i.e. from two different cameras, can replicate stereoscopic human vision in the sense that the two perspectives give us a clue about how far away objects are. I also learned a little more about inside-out tracking which not only uses cameras all around the outside of the VR device but also uses lasers which lets it send signals and measure distances based on how long it took for the laser light to reach the object and be reflected backwards. This method seems a lot simpler to implement then just using cameras which I'd imagine has pretty complex algorithms behind them.
