Disclosed is a virtual content experience system. In the virtual content experience system, a central server for driving the system contains: a content conversion unit which converts two-dimensional image content, received by means of a data transmission and reception unit or input by a user, into a stereoscopic image; a motion information generation unit which recognizes text information extracted from the two-dimensional image content and converts the text information into motion information; a content playback control unit which is provided to transmit the motion information to a motion information management unit provided in a virtual reality experience chair, or receive start information and end information about the motion information from the motion information management unit to generate and change control information for controlling whether to provide new two-dimensional image content; and a display unit for displaying the content conversion unit, and the motion information or control information.

A display system comprises an image source generating left and right components of a stereoscopic image, a screen adapted to display the left and right image components, a light source emitting parallel light strips, a lenticular panel having parallel lenses for directing light from the light source toward the screen, and a tracking system of a position of a viewer. A controller receives the position of the viewer, in a first timeslot causes the image source to generate the left component of the stereoscopic image while controlling lighting of some light strips directed by the lenticular panel through the screen and toward the left eye of the viewer and, in a second timeslot causes the image source to generate the right component of the stereoscopic image while controlling lighting of other light strips directed by the lenticular panel through the screen and toward the right eye of the viewer.

The present invention relates to a near-eye display device. The a near-eye display device includes a display, a first lens disposed in front of the display so as to be spaced apart from the display by a predetermined distance, a dynamic aperture adjustment element disposed adjacent to the first lens to dynamically control an aperture size of the first lens and a horizontal position of the aperture on a plane perpendicular to an optical axis, a main optics lens disposed to be spaced apart from the first lens by a predetermined distance, and a control system configured to control the dynamic aperture adjustment element.

A head-mounted device includes a first light field camera, a second light field camera, a first light field display, a second light field display and a supporting structure. Each of the first light field camera and the second light field camera includes, in order from an object side to an image side, a lens group, a collimator and an image sensor. Each of the lens groups includes a plurality of lens units. The lens units are arranged in a two-dimensional lens array, and each of the lens units includes a lens container and a plurality of lens elements. A first engaging structure is disposed between at least two adjacent lens elements of the lens elements.

Aspects of the subject disclosure may include, for example, embodiments include obtaining video content, the video content comprises a plurality of frames, monitoring, by an image sensor, a facial feature of a user to determine a visual focus of the user in relation to the video content, and detecting from a group of frames of the plurality of frames at least a reduction in movements of objects in the group of frames. Further embodiments include determining, according to the monitoring and the detecting, a measure of attention of the user within a region of the group of frames, determining that the measure of attention of the user within the region of the group of frames satisfies a threshold, and embedding in at least a portion of subsequent frames of the plurality of frames a visual advertisement in the region via a communication device. Other embodiments are disclosed.

It is an objective of the invention of the present application to provide an image display apparatus capable of reducing a change in a display state of a virtual image that depends on a change in a viewpoint position. An image display apparatus according to an embodiment of the present technology includes an emission unit, a diffractive optical element, and an emission control unit. The emission unit emits image light of a target image. The diffractive optical element includes an incident surface and an emission surface, diffracts the image light entering the incident surface, emits the image light from the emission surface, and displays a virtual image that is the target image. The emission control unit controls emission of the image light by the emission unit by using image data generated in accordance with a change in a display state of the virtual image that depends on a change in a viewpoint position.

A method performed by an electronic device for requesting tiles relating to a viewport of an ongoing omnidirectional video stream is provided. The ongoing omnidirectional video stream is provided by a server to be displayed to a user of the electronic device. The electronic device predicts for an impending time period, a future head gaze of the user in relation to a current head gaze of the user, based on: A current head gaze relative to a position of shoulders of the user, a limitation of the head gaze of the user bounded by the shoulders position of the user, and a current eye gaze and eye movements of the user. The electronic device then sends a request to the server. The request requests tiles relating to the viewport for the impending time period, selected based on the predicted future head gaze of the user.
