Abstract
Designs useful for switchable “Virtual Reality,” “Augmented Reality,” and “Mixed Reality” (VR/AR/MR) devices, for combining real reality and simulated reality images, other display purposes, and more. Various methods are proposed to combine (or not) real reality with simulated reality through the use of some level of zooming, cloaking, and/or other techniques. This enables a switchable VR and AR/MR system that does not require transparent glasses or devices. Various systems and methods are presented, some that can be generalized to novel imaging and display techniques that have broad applications beyond VR, AR, MR and other fields.
