Abstract: An information output apparatus (3) includes an acquisition unit (341) that acquires detection information indicating a detection state of a predetermined reaction of a user when the user views a predetermined space which is a virtual reality space or an augmented reality space, and an output unit (342) that outputs information indicating the predetermined space and the detection information acquired by the acquisition unit (341) in association with each other. The acquisition unit (341) acquires detection information in which (i) the detection state of the predetermined reaction when the user watches the video showing the predetermined space and (ii) information indicating a playback position of the video are associated with each other, and the output unit (342) outputs information indicating the detection state of the predetermined reaction for each playback position of the video.

Abstract: An information processing apparatus includes: an information acquiring part that acquires selected image identification information for identifying one or more selected images selected from a plurality of space images, corresponding to a plurality of regions in a space to be looked at from a plurality of positions in the space, by a viewer who views the plurality of space images; a viewing state specifying part that specifies a viewing time of each of the one or more selected images selected by the viewer; and an output part that outputs one or more thumbnail images corresponding to the one or more selected images in a manner corresponding to the viewing time.

Abstract: A topology specifying method includes: acquiring object information that shows a shape of a visible object viewed by a user, and viewing position information that shows a position or movement of the user's view in a visual recognition area viewed by the user, and specifying a topology of the visible object that is associated with the user's impression of the visible object on the basis of a shape of the visible object included in the object information, and outputting information associated with the visible object and topology information that shows the specified topology in association with the each other.

Abstract: A method for generating camerawork information includes extracting, from design information of an architectural structure, a plurality of pieces of space information showing a plurality of spaces related to the architectural structure, specifying a reference line that passes through two connected spaces included in a space shown by a plurality of pieces of extracted space information and is used as a reference when a video image is configured, and generating camerawork information showing time-series information concerning at least one of an image-capturing position, an image-capturing direction, and an image-capturing movement direction in the two spaces on the basis of the specified reference line and the space information corresponding to each of the two spaces for which the reference line is specified.

Abstract: An information recording/reproducing system has a data storage device that stores a data stream with a predetermined data format and an information recording/reproducing apparatus, which is connected with the data storage device, for recording and reproducing the data stream. The apparatus includes information recording/reproducing portion and memory portion that stores plural species of empty data file bodies each in which additional information corresponding to a species of data format and data are assigned to loading regions. The apparatus also has selection portion that selects an empty data file body with a specified data format from the plural species of empty data file bodies. The apparatus further has information-loading portion that loads the additional information and the data into predetermined loading regions assigned in the empty data file body that has been selected by the selection portion.
