A video transmissive head-mounted display device capable of avoiding danger to a user when worn by the user has an external world image acquired by a first image inputting unit, and the external world image is displayed on a display unit. The head-mounted display device has a second image inputting unit that acquires a binocular image of a wearer. The head-mounted display device is configured so that a control unit determines, from the binocular image of the wearer acquired by the second image inputting unit, that the wearer is awake when both eyes are closed for no longer than a predetermined period of time and that the wearer is asleep when both eyes are closed for a predetermined period of time or longer, and the display unit displays the external world image acquired by the first image inputting unit when the wearer wakes from sleep.

A display device including a base, a head spaced apart from the base and including a display panel, a pole extending from the base toward the head, a connector coupled to the head, an elevating module coupled to the pole and moving at the pole in a length direction of the pole, and an arm including one side connected to the connector and the other side connected to the elevating module, wherein the connector includes a front bracket coupled to the head at a rear of the head, a rear bracket rotatably connected to the front bracket with a pivot axis, and a holder rotatably connected to the rear bracket with a tilt axis, wherein the holder includes a holder body rotatably connected to the tilt axis, and a rotation body connected with the holder body and the one side of the arm, wherein the arm comprises a swivel groove formed at the one side of the arm, wherein the rotation body of the holder is inserted into the swivel groove of the arm and rotates at the swivel groove with respect to a swivel axis, wherein an upper bushing washer includes a tooth at an edge of the upper bushing washer, wherein the upper bushing washer is disposed on an upper side of the rotation body and the tooth of the upper bushing washer is inserted and fixed in the rotation body, wherein a lower bushing washer includes a tooth at an edge of the lower bushing washer, wherein the lower bushing washer is disposed on a lower side of the rotation body and the tooth of the lower bushing washer is inserted and fixed in the rotation body, wherein an upper fixing washer includes a tooth at an edge of the upper fixing washer, wherein the upper fixing washer is disposed on an upper side of the swivel groove of the arm and the tooth of the upper fixing washer is inserted and fixed in the arm, wherein a lower fixing washer includes a tooth at an edge of the lower fixing washer, wherein the lower fixing washer is disposed on a lower side of the swivel groove of the arm and the tooth of the lower fixing washer is inserted and fixed in the arm, and wherein the swivel axis is inserted into the upper fixing washer, the upper bushing washer, the lower bushing washer, and the lower fixing washer.

An object is to provide a head-mounted display apparatus that makes it possible to accurately determine a mounting deviation. The technology provides a head-mounted display apparatus including a sensor that detects a change in position of the head-mounted display apparatus relative to a head. The technology further provides an image display system including the head-mounted display apparatus and an information processor that sends image data to the head-mounted display apparatus. The technology further provides an image display method including a detection step of detecting the change in position of the head-mounted display apparatus relative to the head, and an adjustment step of adjusting a position to which the head-mounted display apparatus projects image display light on the basis of the change in position detected in the detection step.

A virtual image display device displays a virtual image by projecting a display light of an image toward a projection unit, and includes: a display unit configured to emit the display light; and a diffraction reflection element configured to reflect the display light emitted from the display unit by diffraction. The diffraction reflection element has a plate shape along a horizontal plane. The diffraction reflection element is configured to emit the display light toward the projection unit arranged above the diffraction reflection element when the display light is incident, and is set such that an angle of incidence on the diffraction reflection element is larger than an angle of emission from the diffraction reflection element.

Embodiments relate to a thermally protective structure that is a case or enclosure for a media communication device (e.g., a set-top box). The thermally protective structure has a plurality of structural feature formations with facets constructed in or on its outer surface to increase the surface area through which heat is dissipated.

An image in content data to be sent out from an information processing apparatus to an HMD is configured such that images obtained by performing correction for left and right parallax images taking distortion of an image by a lens provided in the HMD into consideration are juxtaposed side by side. Further, graphics are displayed in regions of the image, which are invisible when the image is viewed through the lens, and a notification matter from the information processing apparatus is embedded into the graphics depending upon the color, pattern, and shape. The HMD specifies the notification matter corresponding to the graphics and changes the later output mode.
