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: 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.
