Passthrough AR
Currently, there are two basic types of AR glasses: transparent and Passthrough. Most AR headsets, like Microsoft's HoloLens 2, are transparent. The user sees the real image directly from the glass, and virtual objects are superimposed on this glass.
The technology behind transparent AR optics is still in development. The field of view is narrow and virtual objects are not completely opaque.
Passthrough glasses like the LYNX-R1 use the same type of display system as VR glasses, instead of creating a fully virtual world as they view the real world through cameras, the glasses get support from the camera and show you the real world. While the real world will not look very good, this allows for a much wider field of view like AR, as well as full virtual object opacity and lower cost (the price of HoloLens 2 is $ 3500).
In fact, these kinds of products, including Lynx, are called "Mixed reality headsets".
LYNX-R1 is not the first-pass AR headset. Varjo XR-1 and XTAL are products with similar abilities, such as the Vrvana Totem purchased by Apple.
However, other 6DoF glasses must be connected to a PC for it to work. Like the LYNX-R1 Oculus Quest, it is standalone and wireless, with built-in computer, hardware and battery.
There are four cameras on the outside. Two black and white cameras provide positional tracking, and two colored cameras are used for transition and computer vision tasks such as occlusion mapping and hand tracking, including motion recognition.
There are eye tracking cameras in the MR headset. The headset also has two speakers and two microphones that provide positional sound and communication.
