⭐ Core Definition: Head-mounted displays

A head-mounted display (HMD) is a display device, worn on the head or as part of a helmet (see helmet-mounted display for aviation applications), that has a small display optic in front of one (monocular HMD) or each eye (binocular HMD). HMDs have many uses including gaming, aviation, engineering, and medicine.

Virtual reality headsets are a type of HMD that track 3D position and rotation to provide a virtual environment to the user. 3DOF VR headsets typically use an IMU for tracking. 6DOF VR headsets typically use sensor fusion from multiple data sources including at least one IMU.

Head-mounted displays in the context of Pose tracking

In 3D human-computer interaction, positional tracking, also called pose tracking, is a process that tracks the position and/or orientation of head-mounted displays, controllers, or other input devices within Euclidean space. Pose tracking is often referred to as 6DOF tracking, for the six degrees of freedom in which the objects are often tracked.

In some consumer GPS systems, orientation data is added additionally using magnetometers, which give partial orientation information, but not the full orientation that pose tracking provides.
