Utility model patent consisting of a structure (1) made of specific materials assembled so as to allow a proper view of the holographic content in its interior, in such a manner that the structure (1) has two parts: a lit up stage (2), the lights of which are powered by portable batteries, and a stage cover, inside of which there is an flat acetate sheet (3) in a specific angle so that the holographic contents, treated by the software, are displayed mid-air for those who use such device; when the software (app) starts up, users may choose the contents they desire to watch and then put the cell phone (4) within the structure of the portable holographic device (1), through an opening (5), in an area called projection pool, so that the digital content displayed on the cell phone interacts with the sheet creating holographic images.

Various aspects of the present disclosure generally relate to a sensor module. In some aspects, a sensor module may include a collar configured to be attached to a camera module for a user device. The collar may include a first opening that is configured to align with an aperture of a camera of the camera module, and a second opening. The sensor module may include a sensor embedded in the collar. The sensor may be aligned with the second opening of the collar. Numerous other aspects are provided.

An ultrasonic apparatus (100) for creating a holographic ultrasound field (1) comprises an ultrasound source device (10) being adapted for creating an ultrasound wave, and a transmission hologram device (20) having a transmission hologram (21) and an exposed acoustic emitter surface (22), said transmission hologram device (20) being acoustically coupled with the ultrasound source device (10) and being arranged for transmitting the ultrasound wave through the acoustic emitter surface (22) and creating the holographic ultrasound field in a surrounding space, wherein the acoustic emitter surface (22) is a smooth surface which do not influence the field distribution of the ultrasound wave. Furthermore, a method of creating a holographic ultrasound field in an object (3), wherein the ultrasonic apparatus (100) is used, and applications of the ultrasonic apparatus (100) are described.

An apparatus generates a coherent illumination beam. An embedded light-scattering apparatus in a transparent substrate illuminates a reflective optical element which is also embedded inside the same substrate. The reflective optical element is designed to provide a desired beam profile.

A method forms an image with a reconfigurable array of mirrors. The method includes configuring the array by translating some of the mirrors such that distances of the mirrors of the array from a reference plane have a non-uniform spatial distribution. The method includes illuminating the configured array with a coherent light beam such that part of the light beam is reflected off the array and is projected on a planar viewing screen.

The present invention discloses an article of jewelry, preferably a necklace with a hologram. The disclosed apparatus is provided with a hologram to display various things within the necklace and make it appear more stylish and enhancing the decorative appeal. The disclosed apparatus is capable of interacting with the multimedia devices like phone and can connect with them to display images and other things present in them via hologram in the necklace.

A mixed reality accommodation system and related methods are provided. In one example, a head-mounted display device includes a plurality of sensors and a display system for presenting holographic objects. A mixed reality safety program is configured to receive a holographic object and associated content provider ID from a source. The program assigns a trust level to the object based on the content provider ID. If the trust level is less than a threshold, the object is displayed according to a first set of safety rules that provide a protective level of display restrictions. If the trust level is greater than or equal to the threshold, the object is displayed according to a second set of safety rules that provide a permissive level of display restrictions that are less than the protective level of display restrictions.

Embodiments that relate to displaying holographic keyboard and hand images in a holographic environment are provided. In one embodiment depth information of an actual position of a user's hand is received. Using the depth information, a holographic hand image representing the user's hand is displayed in a virtual hand plane in the holographic environment. In response to receiving a keyboard activation input from the user and using the depth information, the holographic keyboard image is adaptively displayed in a virtual keyboard plane in the holographic environment at a virtual distance under the holographic hand image representing the user's hand.

A mobile terminal including a touchscreen; a wireless communication unit configured to wirelessly communicate with an external watch terminal having a holography module disposed in a band of the watch terminal and being worn by a user; a sensing unit configured to sense a gesture of the user; and a controller configured to display a launch screen of a prescribed application on the touchscreen, receive a prescribed gesture sensed through the sensing unit, and control the wireless communication unit to transmit a control command to the external terminal to output a holographic image corresponding to the launch screen, in response to the received prescribed gesture.

Various aspects of the present disclosure generally relate to a sensor module. In some aspects, a sensor module may include a collar configured to be attached to a camera module for a user device. The collar may include a first opening that is configured to align with an aperture of a camera of the camera module, and a second opening. The sensor module may include a sensor embedded in the collar. The sensor may be aligned with the second opening of the collar. Numerous other aspects are provided.
