A [[head-mounted display]] ('''HMD''') is a [[display]] [[device]], worn on the head or as part of a [[helmet]] (see [[Helmet-mounted display]]), that has a small display optic in front of one ([[monocular]] HMD) or each eye ([[binocular]] HMD). HMDs serve various purposes, including gaming, aviation, engineering, medicine, and are the primary delivery systems for [[Virtual Reality]] (VR), [[Augmented Reality]] (AR), and [[Mixed Reality]] (MR) experiences, particularly when supporting a seamless blend of physical and digital elements.<ref name="Sutherland1968">Sutherland, Ivan E.

HMDs function by presenting imagery, data, or a combination thereof directly to the wearer's visual field. Many modern HMDs are [[stereoscopic]], featuring separate displays or distinct images rendered for each eye to create a sense of depth through [[binocular disparity]]. Examples include VR headsets like the [[Meta Quest 3]] and [[Valve Index]]. Other HMDs, particularly earlier AR devices or specialized notification displays like the original [[Google Glass]], may be monocular, presenting information over only one eye.<ref name="GoogleGlassPatent">Heinrich, Jerome (assignee: Google Inc.)
