A display apparatus that enhances a response speed while suppressing reduction in durability even when the transmittance control is performed. The display apparatus includes a display, a plurality of light adjustment devices, and a controller. The display is configured to be attached to a head of a user to display information to the user. Each of the plurality of light adjustment devices is configured to change a transmittance to adjust an intensity of light incident from outside. The controller is configured to independently control the transmittances of the plurality of light adjustment devices separately from each other.

Display apparatus and display method

A monocular image display device includes a virtual image former to display an image in front of one eye of a user and a primary light amount adjuster being in front of another eye of the user. The primary light amount adjuster is disposed closer to the one eye of the user than an optical axis of the another eye of the user is.

Monocular image display device

A management server communicable with a plurality of terminal devices, including a first terminal device, includes: a receiver to receive, from the first terminal device, shared information to be shared between the plurality of terminal devices, the shared information including first location information indicating a current location of the first terminal device, direction information indicating a direction that the first terminal device faces, and distance information indicating a distance from the first terminal device to a target destination; circuitry to generate target destination information including second location information indicating a location of the target destination based on the shared information received from the first terminal device; and a transmitter to transmit the target destination information to the plurality of terminal devices for display at the plurality of terminal devices.

Apparatus, system, and method of information sharing, and recording medium

A user terminal apparatus includes an input receiver, an intersecting-image information obtaining unit and a divider. The input receiver receives input information relating to image-drawing and image-erasing. The intersecting-image information obtaining unit obtains image-drawing input information intersecting image-erasing input information as intersecting-image information when the input receiver receives image-erasing input information. The divider divides the intersecting-image information to erase a portion of the intersecting-image information contained in an erasing area computed from the image-erasing input information when the input information is image-erasing input information.
