Inside-out tracking is a method of positional tracking commonly used in virtual reality (VR) and augmented reality (AR) technologies.

It refers to 3D tracking that is egocentric.

Inside out tracking was invented in 1984 by Gary Bishop. As part of his 1984 dissertation on Self-Tracker, Bishop put forward the idea of outward-looking tracking systems based on user-mounted sensors that estimate user pose by observing landmarks in the environment.[1]

SteamVR tracking is technically inside-out tracking, because the unique data per frame is generated on the user-mounted device, rather than the external base stations.

It usually involves SLAM or VIO.
