For applications where stereo 3D viewing is required (without head tracking), DRV delivers a bright, high resolution stereo image at a comfortable viewing distance. DRV doesn’t suffer from the problems associated with the use of VR goggles, such as, screen door effect, VR motion sickness, isolation, eye-strain, “welders neck”, hygiene. The advantage of not having to wear VR goggles also means the user can comfortably wear their prescription glasses, if needed, and retain their peripheral vision for easy reference to documents, instruments and colleagues.
