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.
