How Oculus squeezed sophisticated tracking into pipsqueak hardware

Making the VR experience simple and portable was the main goal of the Oculus Quest, and it definitely accomplishes that. When you move your head and hands around with a VR headset and controllers, some part of the system has to track exactly where those things are at all times. Both have their merits, but if you want a system to be wireless, your best bet is inside-out, since you don't have to wirelessly send signals between the headset and the computer doing the actual position tracking, which can add hated latency to the experience.
