Mixed reality glasses allow, a user to input into the glasses, to operate a device sanitarily. The glasses are connected, to the device wirelessly. The user views holograms in mid-aid air, while looking through the glasses. The holograms are input buttons, for the device. The user's input into the glasses, activates the holographic input buttons. User input devices in the glasses detect the user's input. User input devices include, an eye tracker, a voice recognition device, an eye gaze and hand gesture input device, a touch input device, and a thought input device. The devices operated by the glasses, may include, an elevator, a smart toilet, and a medical device. The user operates the device, touch freely, without touching the device's physical input buttons. Contact with harmful bacteria is deceased by operating the device, touch freely, which avoids bacteria, that may be on the device's input buttons.

Systems and methods are provided for selectively controlling a carry mode for holograms presented in mixed-reality environments and for providing leashing buffers for the holograms. The carry mode enables holograms to be functionally moved within a single mixed-reality environment, and out into one or more different mixed-reality environments. The carry mode can be automatically applied to holograms created within the mixed-reality environment. The carry mode can also be applied responsive to user input applied to world-locked holograms, which triggers a switch from the world-locked mode to the carry mode from. Holograms can also be leashed for persistently displaying holograms associated with or linked to a user in the mixed-reality environment to provide the user increased accessibility to the hologram while navigating within and without a particular mixed-reality environment. Selectable options are presented with a hologram in carry mode for switching from the carry mode to the world-locked mode.

The invention relates to a minimalistic pair of AR glasses having very high resolution, any field of view, total transparency, continuously variable object focal length, minimal eye lights and a projector unit behind the ear without any socially harmful indications of technology around the user's face. An integral image grid is constructed in a rimless pair of glasses, wherein, using multimode glass fiber projectors and MEMS switch rods the individual images are delivered directly before the eye by means of gradient-index camouflaged-optical-unit tubes, preferably by means of a combination of multimode glass fiber projectors for indiscernibly supplying high-resolution holographic projections, an integral imaging concept for resolution of any level and any field of view, fast SLM DMD chips for huge image-generation throughput, a gradient-index camouflaged optical unit for perfectly concealed hardware in rimless glasses lenses, and an eye-tracking-controlled adaptive resolution controller for producing huge virtual resolutions.
