===Motion Tracking=== | ===Motion Tracking=== | ||
[[ | HMD [[tracking|tracks]] the movement of your head and updates the rendered scene based on its orientation and location. This process is similar to how we look around in real life. There are 2 types of tracking: [[rotational|rotational tracking]] and [[positional tracking|positional]]. | ||
[[Positional | [[Rotational tracking]] tracks the 3 rotational movements: pitch, yaw, and roll. It is performed by [[IMUs]] such as [[accelerometer]]s, [[gyroscope]]s and [[magnetometer]]s. | ||
[[Positional tracking]] tracks the 3 translational movements: forward/back, up/down and left/right. Positional tracking is usually more difficult than rotational tracking and is accomplished through different [[Positional tracking#Types|Types]] and [[Positional tracking#Systems|Systems]]. | |||
Motion tracking is not only used to track your head in HMDs but also used to track your hands and rest of your body through various [[Input Devices|input devices]]. | |||
