	The 3 translational movements are left/right, forward/backward and up/down. ~~These~~ movements are usually tracked by an external camera or other sensors. Few HMDs use on-board sensors to track translational movements.		The 3 translational movements are left/right, forward/backward and up/down. Three dimensions are also referred to as X,Y,Z, but some people and programs use XYZ to mean lateral,vertical,depth, in that order, whereas others use it to mean lateral,depth,vertical, or others. Translational movements are usually tracked by an external camera or other sensors. Few HMDs use on-board sensors to track translational movements.

			Tracking absolute translational position based on movement measurements is called dead reckoning.

	The ability to track translational movements is required for [[positional tracking]].

	'''Degrees of freedom''' or '''DOF''' is the ways an object can move within a space. There are a total of 6 degrees of freedom in a 3 dimensional space. The 6 DOF can be divided into 2 categories, rotational movements and translational movements. Each category has 3 DOF. The original [[Oculus Rift DK1]] only had 3DOF. Oculus Rift headsets DK2 and later, and [[SteamVR]] [[HMD]]s all have 6 DOF. Both [[rotational tracking\|orientation tracking]] (rotation) and [[positional tracking]] (translation) are required to have a truly [[immersion\|immersive]] [[VR]] experience.
