[[Discrete HMD]] also known as Tethered HMD supplies everything required for an [[immersive]] [[VR]] experience aside from the processing. It contains display, lenses, rotational tracking, [[positional tracking]], audio and advanced input. For processing, Discrete HMDs are connected to PCs through cables. While this type of HMD is less mobile than its 2 counter parts, it is able to deliver the best VR experience.

[[Integrated HMD]] is the most sophisticated and expensive type of HMD and [[OHMD]]. This independent computing device is able to deliver [[VR]] and/or [[AR]] experiences without any external hardware such as PC or smartphone. It contains everything from display to processors to camera and is able to display stereoscopic 3D images, perform complex tracking and utilize advanced input methods. Currently, most of Integrated HMDs are AR OHMDs with high price point and target only business professionals. Popular Integrated HMDs:*[[Microsoft HoloLens]]*[[Google Glass]]*[[Magic Leap]]
