[[Discrete HMD]] also known as '''Tethered HMD''' is a type of mostly [[virtual reality]] [[head-mounted display]] that supplies everything required for an [[immersive]] [[VR]] experience aside from the processing. It contains [[display]], [[lenses]], [[rotational tracking]], [[positional tracking]], [[audio]] and [[Input Devices|advanced input]]. For processing, Discrete HMDs are connected to PCs through cables. Certain Discrete HMDs such as the [[PlayStation VR]] use consoles instead of PCs for processing. While this type of HMD is less mobile than its 2 counter parts, it is able to deliver the best VR experience. To deliver positional tracking, Discrete HMDs utilize external sensors that are placed external to the user or HMD. They also have custom [[Input Devices]] built with 6[[DOF]] tracking in mind. Note that newer Discrete HMD such as [[Pico Neo 2]] is not tethered to its PC, instead it wirelessly streams from the PC to the HMD.
