VIDEO/AUDIO PRESENTATION DEVICE, VIDEO/AUDIO PRESENTATION METHOD, AND PROGRAM

WIPO Patent Application WO/2020/166402

A1

Provided is a video/audio presentation device that makes it possible to present video and audio for sports training in such a way that physical reactions are unlikely to be delayed. The video/audio presentation device includes: an offset determination unit in which chronological data regarding a physical reaction to an inbound flying object in a real space is denoted by physical reaction Areal, chronological data regarding a physical reaction to an inbound flying object represented in a virtual space is denoted by physical reaction AVR, chronological data regarding a physical reaction to an inbound flying object represented in a semi-virtual space is denoted by physical reaction Amix, the time difference between Areal and Amix or the time difference between AVR and Amix is denoted by tdiff, the time difference tdiff is corrected on the basis of a correction coefficient α, and a chronological offset toffset is thus determined; a video presentation unit that presents a video in the semi-virtual space; and an audio presentation unit that uses the chronological offset toffset as a basis to shift audio corresponding to the video to a timing earlier than that of the video and presents the shifted audio in the semi-virtual space.
