In an 'inside-out' system, the tracking camera is placed within the item being tracked (for our purposes, like a [[Virtual_Reality#Devices|head mounted display]]), from which vantage point it look ''out'' at the world around it. It uses its changing perspective on the outside world to note changes in position. | In an [[inside-out tracking|'inside-out' system]], the tracking camera is placed within the item being tracked (for our purposes, like a [[Virtual_Reality#Devices|head mounted display]]), from which vantage point it look ''out'' at the world around it.
