Optical cloaking allows completely opaque VR devices to be "cloaked," switching to AR or MR while providing correct three-dimensional (3D) parallax and perspective of the real world, without the need for ...
A simplified stereoscopic system with two cameras and existing VR systems can be an approximation for limited VR, AR, or MR. ...
Hence, the device should be cloaked to be 'invisible,' or transparent, by its own display. ...
