Abstract: Provided is a technique capable of setting an appropriate link destination when there are a plurality of link destination candidates among data files. A file management system according to the present invention determines a type of a target indicated by a character string described in a data file to determine whether the target matches among data files and assigns a link among the data files when the target matches.

Abstract: A work assistance system includes a drawing, a work record table, a handwriting display determination unit, a display control unit, and input means. The drawing includes parts and handwritings. The work record table stores the handwriting for the part as the work record. The handwriting display determination unit determines, as the writing candidates, the handwritings not associated with the parts based on the work record table. The display control unit displays the writing candidates and the parts via the input means in a selectable manner on a data display unit of a terminal of a user.

Abstract: A head mounted display device includes: a mounting state sensor (for example, a sensor) in which a sensor value changes according to a mounting state; a mounting state determination unit for determining a mounting state according to an output of the mounting state sensor; a storage unit for storing a content to be displayed; a content control unit for changing the content stored in the storage unit; and a display unit for displaying the content stored in the storage unit. The content control unit changes the content according to the mounting state output by the mounting state determination unit.

Abstract: A display system includes a display and a detector configured to detect an orientation of the display. The display system includes a display source image generation unit configured to generate a display source image including a first image and a second image related to this first image; and a visual field image display unit configured to display the first image in a first display region of the display and display the second image in a second display region of the display. The visual field image display unit is configured to set a predetermined fixed region of the display as the first display region when a display mode associated with the first image is a first display mode, and determine the first display region according to the orientation of the display when the display mode is a second display mode.

Abstract: The invention provides a face authentication system robust to the individual differences in the face parts or changes in the face orientation when an individual is identified by using a face image in a state of wearing a wearable item. The face authentication system according to the invention identifies an individual by using a synthesized image obtained by deforming a wearable item image to fit a face shape of the individual.
