There are three different ways that an object can rotate, we call each of these ways a [[degrees of freedom]], and you can track any number of degrees of freedom. The three rotational degrees of freedom are: | ||
*'''Pitch''' | *'''Pitch''' - Tilting backward and forward, like a plane ascending or descending | ||
*'''Yaw''' | *'''Yaw''' - Left and right movement, like a plane turning left or right while remaining level | ||
*'''Roll''' | *'''Roll''' - Clockwise or counter-clockwise movement, like a plane banking to make a turn | ||
In order to get an accurate idea of exactly how an object is oriented, all three types of rotation have to be measured. Traditionally this would be done using devices called [[IMUs]] implanted into an object. | In order to get an accurate idea of exactly how an object is oriented, all three types of rotation have to be measured.

Rotational tracking is a vital technology used not only in [[VR Devices|VR]] and [[AR Devices|AR HMDs]] but also in [[Input Devices]]. | |||
