'''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. [[Oculus Rift | '''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. | ||
