TRACKING SYSTEMS




       Inertial Tracking


         ●     Inertial sensors are not only capable of tracking rotational movement (roll, pitch,

               yaw), but also translational movement.

         ●     These two types of movement together are known as the Six degrees of freedom.

         ●     Many applications of virtual reality need to not only track the users’ head

               rotations, but also how their bodies move with them (left/right, back/forth,
               up/down).

                 ○    Six degrees of freedom capability is not necessary for all VR experiences,

                      but it is useful when the user needs to move things other than their head.
