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 including a gaze detection device detecting a gaze of a user; and a tracking unit that determines a gaze point of the user in the three-dimensional image on the basis of the gaze directions of the right and left eyes, in which the first detection unit calculates a right eye gaze vector indicating the gaze direction of the right eye, and the second detection unit calculates a left eye gaze vector indicating the gaze direction of the left eye, wherein a display unit displays a three-dimensional image consisting of a plurality of layers in a depth direction, and a tracking unit identifies the layer that the user is gazing at by selecting the layer having a shortest distance between intersection points of the right eye gaze vector and the left eye gaze vector with each layer.

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: 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: An external imaging system for performing imaging by easily operating an external imaging camera is provided.
