Augmented reality headset
An augmented reality headset (AR headset) is a type of head-worn gadget that enables the wearer to have an augmented reality experience. Augmented reality headsets rely on the optics, and 3D tracking.
Examples of AR headsets are the Microsoft Hololens, the Magic Leap 1, and Project North Star.
In the Magic Leap and Hololens, the image only takes up a small part of the piece of glass for each eye. There is typically a small square in the center that is the actual display.
AR headsets either have a built-in computer and battery, or must use an external computer and battery. The Magic Leap devices use an external computer and battery. Project North star uses an external computer. HoloLens 1 and 2 have it all in the headset.
AR headsets show virtual 3D objects in the real world to the viewer. Typically they are optical-see-through. They are a step up from smartglasses.
AR headsets require a display such as an optical see-through display, a 3D tracking system such as an ultrasonic tracking system, and a connected computer system.
AR headsets are great if they have a wide field of view and a wide range of focus. AR headsets are only OK if the display takes up the entire piece of glass per eye.
The content shown on AR headsets is aligned in 3D to the real world.

Constitution[edit]
AR headsets that solve the vergence-accommodation conflict require light field displays or holographic displays.
AR headsets are most useful when they are completely standalone. AR headsets can be wired into a separate computer, or they can have data wirelessly transmitted to them for rendering. However, using a separate unit connected to the headset increases the complexity of using them.
Optics[edit]
Optics for AR headsets approximate a light field to the wearer's eyes at each instant.
