Abstract
A video and audio presentation device configured to present video and audio for sports training with less delay in physical reaction is provided. The device includes: an offset determination unit configured to determine a time-series offset tobtained by correcting a time difference ton a basis of a correction coefficient α, the time difference trepresenting a time difference between Aand A, or a time difference between Aand A, where a physical reaction Arepresents time-series data of physical reaction to an incoming object in a real environment, a physical reaction Arepresents time-series data of physical reaction to an incoming object presented in a virtual reality environment, and a physical reaction Arepresents time-series data of physical reaction to an incoming object presented in a semi-virtual reality environment; a video presentation unit configured to present video in the semi-virtual reality environment; and an audio presentation unit configured to shift audio corresponding to the video on a basis of the time-series offset tso that the audio precedes arrival of the video, and to present the shifted audio in the semi-virtual reality environment.
