Abstract: Provided is a virtual-reality provision system having: a tracking data acquisition unit that acquires tracking data on a flying object thrown by an athlete, the data being obtained from sensor information from a sensor that tracks the flying object; a three-dimensional-display-data generation unit that uses the acquired tracking data to generate three-dimensional display data used to display, in a virtual space, a flight video of a virtual flying object corresponding to said flying object; at least one virtual-space provision system that displays the flight video of the virtual flying object in the virtual space by using the three-dimensional display data; and a transmission unit that transmits the three-dimensional display data to the at least one virtual-space provision system.
