An image display device includes an inclined transparent plate, a supporting member configured to support a display device with a display to be capable of projecting the image toward the transparent plate, thereby overlapping the image with a frontal view of the object, side walls each extending along one of side faces of the transparent plate. An outline of the frontal view of the object overlaps at least a part of an outline of the image, a perspective view of the object seen through the transparent plate overlaps the image reflected by the transparent plate, and the walls sandwich the transparent plate so that two spaces at upper side and a rear side of the transparent plate are defined, the object being positioned in the rear side space, the upper side space having a brightness different from that of the rear side space.

The present disclosure provides an electronic device including a device body being maintained at a preset position relative to an eye of a user. The device body further includes: a display unit for emitting light corresponding to a display content; and a lens group having a side surface facing the display unit. The light emitted from the display unit is reflected by the side surface to be incident on the eye of the user.

A head-mounted display apparatus includes: a first body formed in the shape of a diving mask to cover up a user's nose and eyes and having vision holes formed at a position where user's eyes are located; a first external body extending forward from the rear end of the first body and surrounding the side of the first body; a second body having a cross section in the shape of inverted with its front face opened and with a lens fixed to a rear face corresponding to the vision hole; and a second external body extending rearward from a front end of the second body to surround the side of the second body and having a terminal mounted on the front end thereof,

An image display device includes a transparent plate which may be disposed in an inclined manner with respect to a display section of a portable terminal provided with the display section. A display displayed on the display section may be reflected on the transparent plate. A space behind the transparent plate may be viewed through the transparent plate and, at the same time, an image on the display section of the portable terminal may also be viewed while being reflected on the transparent plate.

Head-mounted display systems and methods of operation that allow users to couple and decouple a portable electronic device such as a handheld portable electronic device with a separate head-mounted device (e.g., temporarily integrates the separate devices into a single unit) are disclosed. The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted device and the portable electronic device.

A HMD includes an electronic display and a pancake lens block. The pancake lens block includes a back curved optical element and a front curved optical element. Light propagating through the pancake lens block undergoes multiple reflections and to mitigate parasitic reflections, there are no air gaps between optical elements of the pancake lens block. A hybrid film that operates as a waveplate surface and a mirrored surface can be placed between the front curved optical element and the back curved optical element. A wide FOV can be obtained by making the coupling surfaces of the front optical element and the back optical element to be based on a convex cylindrical surface profile and a concave cylindrical surface profile, with the axis of the cylinder surface in a vertical direction for a user wearing the HMD.

The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted device and the portable electronic device.

An apparatus and method for real-time audio processing employs a gaze detection sensor to detect a direction of a user's gaze and output a gaze signal corresponding to the detected direction of the user's gaze. A digital signal processing unit responds to a plurality of signals corresponding to a plurality of sounds received at the apparatus, and the determined direction of gaze to identify a signal of interest from the plurality of signals using the gaze signal. The signal of interest is processed for output to the user. In embodiments, a microphone array provides the plurality of signals. An imaging sensor may work with either the microphone array or the gaze detection sensor to identify the signal of interest.

A head mounted display system comprises a main body configured to be worn on a human head and to secure therein a mobile computing device having a display and hardware for generating images on the display corresponding to motion data. The system further includes a remote controller, distinct from, but in communication with, the mobile computing device, which when detachably attached to the exterior of the main body provides the motion data to the mobile computing device that is used by the mobile computing device in performing head tracking of the human head, the remote controller incorporating a remote controller processor, at least one motion sensor for providing the motion data

An image capture device with a housing comprising a capture opening and a viewing opening arranged opposed to the capture opening. The image capture device comprises a camera for capturing an image of at least a portion of an object arranged in register with the capture opening, as well as a beam-splitter arranged to cover the capture opening, the beam-splitter allowing a first portion of light reflected from an observed object to pass through the beam-splitter, this allowing a user to effectively watch the object during image capture.
