There are many different [[positional tracking]] technologies used to determine the exact position of the user inside the tracking volume and change the viewpoint accordingly. Such tracking helps to blur the line between virtual experiences and the real world. | There are many different [[positional tracking]] technologies used to determine the exact position of the user inside the tracking volume and change the viewpoint accordingly.
