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 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: Problem: The purpose is to reduce the size of a gaze detection device.

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: 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.

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: In a head mounted display to be mounted on a head of a user when being used, a light source can radiate invisible light. A camera images invisible light radiated from the light source and reflected by an eye of the user. An image output unit outputs an image imaged by the camera to a line-of-sight detecting unit configured to detect a direction of a line of sight of the user. A housing accommodates the light source, the camera, and the image output unit.
