The device body includes an upper casing and a lower casing. A feeding portion, a first grounding portion and a second grounding portion are disposed on a periphery of the circuit board. The second grounding portion is electrically connected to the upper casing. The antenna system is disposed on the inner surface of the lower casing. The feeding terminal of the antenna system is electrically connected to the feeding portion of the circuit board. The grounding terminal of the antenna system is electrically connected to the first grounding portion of the circuit board. An end of the conductive extension portion is electrically connected to the upper casing, the other end of the conductive extension portion is extended into the wearable body.

A display apparatus includes a frame mounted on an observer's head, an image display device attached to the frame and a dimming device 700, the image display device includes an image forming device and an optical device 120, 320 having a virtual image forming region 140, 340 where a virtual image is formed on the basis of light emitted from the image forming device, the optical device 120, 320 overlaps with a portion of the dimming device 700, at the time of operation of the dimming device 700, a light blocking ratio of the dimming device 700 is changed over a range of from an upper region 701U to a lower region 701D and/or over a range of from an inner region 701C to an outer region 701S, and a virtual image forming region facing region 701 has a light blocking ratio higher than the light blocking ratio of the lower region 701D or the outer region 701S.

A wearable device according to one aspect of embodiments includes a display unit arranged in front of eyes, and a detector configured to detect whether an electronic device is present in a predetermined space in front of the wearable device. If the another electronic device is present in the predetermined space and performs predetermined display, the wearable device displays additional information related to the displaying on the display unit.

An information processing device causes an information processing section to perform information processing of a game for example, based on a user's operation received by an input information acquiring section and on images acquired by a stereo camera and obtained through an acquired image obtaining section. The information processing device causes an output data generating section to output the result of the information processing to a display device. At this point, a tracking processing section detects corresponding marker images from stereoscopic images and, based on a parallax therebetween, obtains position information about a target object. In accordance with vertical position misalignment between the detected marker images, a calibration determining section determines whether camera calibration is needed and requests the output data generating section to notify the user of the determined need.

Embodiments provide a suitable viewing environment, in accordance with whether a head-mounted display is mounted or detached. A control device includes a state identification unit configured to identify whether a head-mounted display is mounted or detached, and an output control unit configured to control, in accordance with the mounting or the detachment, at least one of sound output and video output from a display device provided separately from the head-mounted display.

There is provided a head-mounted display, a notification apparatus, a notification system, a notification method, and a program that allow a person not wearing a head-mounted display to know that a user still continues to wear a head-mounted display after a notification that a wearing time of the head-mounted display of this user has exceeded a predetermined time. A wearing time determination block determines a wearing time of the head-mounted display of the user. A notification block executes a first notification to the user if the wearing time has exceeded a first time and, when the wearing time has exceeded a second time longer than the first time, and executes a second notification to a person not wearing the head-mounted display.

There is disclosed a display device comprising a display unit comprising a display panel; an AV box configured to form an electric control unit; and a first cable configured to electrically connect the display unit with the AV box, wherein the display unit comprises a source PCB provided in an upper end of a rear surface of the display panel; a second cable configured to connect the upper end of the rear surface of the display panel with an upper end of the source PCB; an interface board provided in a lower end of the source PCB and electrically connected with the source PCB; a third cable configured to connect one side of the interface board with the source PCB; and a module cover configured to cover the rear surface of the display panel, and the first cable is configured to connect the other side of the interface board with the AV box.

A display apparatus in which a height of an AC socket protruding to a rear side of a printed circuit board is reduced and a power cord is provided to be in close contact with a product to provide a display apparatus in which a creeping distance is increased to prevent the printed circuit board from being damaged by a high voltage or a stroke of lightning.

A method for substantially matching a color or pattern of article of clothing or other object so that substantially the same color or pattern can be displayed on a flexible footwear display. The other object may include a user eye, hair or other human body part. The method includes the use of a detector used to determine color or pattern values that match the color or pattern of the clothing or other object. The color or pattern values used to be displayed on the footwear can be determined automatically or by the user. The flexible footwear display may occupy 25% to 100% of the outer surface of the footwear, have a pixel count of 50 to 2,000,000 pixels or a color depth in the range of 8-bits to 48-bits.
