Abstract: [Problem] To reduce the size of a head-mounted display or other typical display device comprising a gaze detection device. [Solution] A gaze detection device comprising a semi-reflective mirror 13 that partly transmits and partly reflects incident light, and one or more gaze analysis cameras that capture images of the user's eye 10 reflected in the semi-reflective mirror 13, wherein the semi-reflective mirror 13 is positioned to face the eyes 10 of the user and images of the user's eye 10 reflected in the semi-reflective mirror 13 are captured by one or more abovementioned cameras.

Abstract: Moving images are switched naturally when development of a story is switched according to a situation. An image display system includes a display unit that displays a moving image, an acquisition unit that acquires a motion of a user viewing the moving image displayed by the display unit, a determination unit that determines whether or not the motion of the user acquired by the acquisition unit satisfies a predetermined switching condition in which the user does not recognize switching between images even when the moving image displayed by the display unit is switched from first moving image data to second moving image data different from the first moving image, and a switching unit that switches the moving image displayed by the display unit from the first moving image data to the second moving image data when the determination unit determines that the switching condition is satisfied.

Abstract: An video display system having room in a generation time of a next frame to be generated on the basis of a gaze direction of the user is provided.

Abstract: A head mounted display includes a lens disposed at a position facing a user's cornea; a plurality of infrared light sources disposed in a periphery of the lens that emit infrared light toward the user's cornea; a hot mirror that reflects the infrared light; a camera that captures an image projected into the hot mirror; an output unit that outputs an image captured by the camera to an eyesight direction detection unit that detects an eyesight direction of the user; and a housing, wherein when the periphery of the lens is divided into four regions: a first corresponding to the outer corner side of the eye, a second corresponding to the inner corner side, a third corresponding to the top side of the head, and a fourth corresponding to the jaw side, the plurality of infrared light sources are disposed in any of the first region and the second region.

Abstract: An eye-gaze detection system containing a mounting tool mounted on a user for use, includes: plural illumination units illuminating an eye of the user with invisible light; a camera capturing the eye on the basis of the invisible light; a pupil specifying unit specifying a pupil center of the user from a captured image having been captured; an obtaining unit obtaining information on a position of a center of a corneal curvature of the user on the basis of disposed positions of the illumination units and the camera, and illuminated positions by illumination light emitted from the illumination units to the eye; a vector specifying unit specifying a vector connecting the center of the corneal curvature and the pupil center on the captured image; and a displacement detection unit detecting displacement of a mounting state of the mounting tool mounted on the user on the basis of the vector.

Abstract: A head mounted display that is mounted on the head of a user and used includes an irradiation unit that irradiates the eyes of the user with invisible light, a monitor that displays an image for the user to view wearing a glass for display that transmits visible light and reflects invisible light, an imaging device capable of capturing an image formed by the invisible light, and an output unit that outputs an image captured by the imaging device as an image for gaze detection, and the imaging device images the eyes of the user using the invisible light radiated from the irradiation unit, reflected by the eyes of the user, and reflected by the glass for display.

Abstract: A facial expression recognition system including a head mounted display including a first camera that images eyes of a user, a second camera that images a mouth of the user, and an output unit that outputs a first image captured by the first camera and a second image captured by the second camera; and a facial expression recognition device including a reception unit that receives the first image and the second image output by the output unit, and an expression recognition unit that recognizes a facial expression of the user on the basis of the first image and the second image.

Abstract: Appropriate reduction of transferred data volume is used to deliver interruption-free video to a user, minimizing viewing discomfort. A head-mounted display secured to the head of a user and a video generating device that generates a video for presentation to the user by the head-mounted display are combined in a video system. In the head-mounted display, a presentation unit presents the video to the user, an imaging unit captures an image of the user's eye, the first communication unit sends the captured image to the video generating device, and receives the video from the video generating device.

Abstract: A gaze detection system includes a head mounted display and a gaze detection device detecting the gaze of the user. The head mounted display illuminate users eyes with infrared light, displays three-dimensional image comprising a plurality of layers in the depth direction and captures an image of user's eye illuminated by the infrared light. The gaze detection device detects the user's right eye's gaze direction (vector) and left eye's gaze direction (vector) with use of the captured images. The gaze detection device identifies the layer that the user is gazing at by selecting the layer having the shortest distance between the intersection points of the right eye gaze vector and the left eye gaze vector with each layer as a gaze point in the depth direction.

Abstract: A head mounted display is used in a state of being mounted on a user's head and includes a convex lens disposed at a position facing the user's cornea when the head mounted display is mounted. An infrared light source emits infrared light toward the convex lens. A camera captures an image including the user's cornea in a subject. A housing houses the convex lens, the infrared light source, and the camera. The convex lens is provided with a plurality of reflection regions that reflects infrared light in an inside of the convex lens. The infrared light source causes a pattern of infrared light to appear on the user's cornea by emitting infrared light to each of the plurality of reflection regions provided in the convex lens.
