A device for mixed reality includes a curved mirror and a first holder. The curved mirror has a concave surface, a convex surface opposite to the concave surface, and a light transmissive medium between the concave surface and the convex surface. The first holder is disposed in front of the concave surface and within a focal length of the curved mirror and configured to support a portable apparatus. The first holder has a curved surface configured to reflect a sound wave from the portable apparatus to the curved mirror.

Systems, methods, and computer program products are presented. The system, for instance, includes a mobile device having a hologram emitter, an imager, memory, at least one processor in communication with memory, and program instructions executable by one or more processor via the memory to perform a method including projecting, from the hologram emitter of the mobile device, a holographic image having a mirror-like reflective surface at a position and an orientation from the mobile device, and obtaining, from the imager of the mobile device, image data and/or video data of a reflection of an object reflected off the projected holographic mirror-like reflective surface.

A system for measuring vibrations of a surface (VSURF) of a mechanical part (M), comprising a source (SOURCE) of radiation (L), a first separator element (ELI) configured to define a first incident ray (LB1) and a reference ray (RLB), a shaping module (DOEM) producing a second incident ray (LB2) from said first incident ray (LB1), and an optical element (OE) capable of an interferential addition of the reference ray (RLB) and a ray produced by a reflection of said second incident ray (LB2) on said surface (VSURF), the shaping module (DOEM) comprising one or more diffracting optical elements (DOE1, . . . , DOEn), each comprising at least one diffraction structure (FSTRUCT) diffracting all or part of the first incident ray (LB1) so as to illuminate a chosen surface of the mechanical part.

Disclosed are methods and systems for displaying images, and for implementing volumetric user interfaces. One exemplary embodiment provides a system comprising: a light source; an image producing unit, which produces an image upon interaction with light approaching the image producing unit from the light source; an eyepiece; and a mirror, directing light from the image to a surface of the eyepiece, wherein the surface has a shape of a solid of revolution formed by revolving a planar curve at least 180 around an axis of revolution.

A near-to-eye display device includes a spatial light modulator. The spatial light modulator modulates an illumination wave to create a virtual-scene wave that is steered to a useful portion of an exit pupil plane. Higher diffraction orders and noise beams are filtered out by the user's pupil acting as a spatial filter.

An augmented reality (AR) system includes a head-mounted display (HMD) with a holographic display, a device for generating virtual reality (VR) light field data, a device for recording light field data of the environment, and a device for combining the light field data of the environment and the VR light field data to form augmented reality (AR) light field data and controlling the holographic display. They AR system further includes a device for correcting the AR light field data on the basis of ophthalmological data of a user. The complete computer-generated AR presentation makes possible a common and uniform adaptation and correction of the presentation in respect of vision defects of the user.

There is provided a near-eye device for augmenting a real world view. The near-eye device comprises a spatial light modulator comprising an array of phase modulating elements arranged to apply a phase delay distribution to incident light. The device further comprises a beam combiner comprising a first optical input arranged to receive spatially modulated light from the spatial light modulator and a second optical input having a field of view of the real world.

A computing device associated with a user obtains contextual data associated with the user. The contextual data includes information indicating a current location of the user relative to the computing device. The computing device selects one or more applications provided by the computing device based on results of an analysis of the contextual data, and projects one or more holographic objects representing the one or more applications into a viewable area located a predetermined distance from the user.

A method, system, and computer program product for holographically displaying and navigating data content of a mobile device is provided. The method may include retrieving data content comprising an arrangement of data objects, wherein a size of the data content exceeds a predetermined threshold. Visualized data content may be generated based on the data content. The visualized data content is rendered for display by holographic projection with respect to on-screen data content, displayed by a touchscreen of the mobile device.
