  • Patent number: 11143870
    Abstract: 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.

  • Patent number: 10942354
    Abstract: 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.

  • Patent number: 9805486
    Abstract: 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.

  • Publication number: 20060095420
    Abstract: A human resources retrieval system includes a client computer and a human resources retrieval device. The client computer and the human resources retrieval device are connected to a network. The client computer specifies a search condition. The human resources retrieval device performs a personnel search and sends a search result to the client computer. The human resources retrieval device includes a profile database, a retriever, and an adjuster. The profile database stores personnel profiles containing human resources data. The retriever searches the profile database for human resources data in accordance with the search condition specified by the client computer. The adjuster adjusts the human resources data by referring to a profile of a searcher and profiles corresponding to the human resources data stored in the profile database.
