The smartphone 12 includes a microphone, and generates sound data obtained by recording sounds from the outside world. The smartphone 12 includes motion data and sound data, and generates motion data with sound, which is data associated with each other on the time axis at the timing at which they are generated.

The moving image data with sound, which is the data associated with each other above, is generated. The imaging unit of the camera 13 is an omnidirectional camera that simultaneously captures 360 degrees in all directions.

  The camera 13 has a function of a streaming server device, can be connected to the Internet 9 via a mobile communication network, and transmits the generated moving image data with sound to the server device 14.

  The hardware of the server device 14 is a computer that includes a processor that processes data according to a program, a memory that stores a program and data used by the processor, and a communication interface that transmits and receives data to and from an external device.

  FIG. 2 is a diagram illustrating a functional configuration of the server device 14. That is, the server device 14 including the components illustrated in FIG. 2 is realized by the computer performing processing according to the server device program according to the present embodiment. The functional configuration provided in the server device 14 will be described below.

  The storage unit 140 stores various data. The receiving unit 141 receives motion data with sound and moving image data with sound from the smartphone 12. The synchronization processing unit 142 generates content data by synchronizing the motion data with sound and the moving image data with sound received by the receiving unit 141 and stored in the storage unit 140. The transmission unit 143 transmits the content data generated by the synchronization processing unit 142 and stored in the storage unit 140 to the motion simulator 11.

The motion data with sound is received and stored for each content identified by the content ID. The motion-added motion data is data in which motion data indicating the motion of the real experience person changing with time and sound data indicating the sound of the outside world surrounding the real experience person are associated with each other on the time axis.

  The motion data with sound is obtained by the smartphone 12 attached to the physical body of the actual experience person or a device (for example, the canoe in the case where the actual experience person experiences the downstream by canoe). It is generated while a person has some experience (such as canoeing) with body movement.

  FIG. 4 is a diagram schematically illustrating a configuration of moving image data with sound that the reception unit 141 receives from the smartphone 12. The moving image data with sound is received and stored for each content identified by the content ID.

It is generated while a person has some experience (such as canoeing) with body movement.

  Time data may accompany sound data with sound and moving image data with sound. However, since the internal clock of the smartphone 12 and the camera 13 is not synchronized, the motion data with sound and the moving image data with sound cannot be synchronized based on the time data. Further, even when the time data accompanying the motion data with sound and the moving image data with sound indicates a relative time based on the recording start time, for example, the motion data with sound and the moving image data with sound are synchronized based on the time data. It is not possible.

  The synchronization processing unit 142 reads out the motion data with sound and the moving image data with sound of the same content ID from the storage unit 140, and is included in the motion data with sound based on the value of the cross-correlation function of the sound data included in those data. The content data is generated by synchronizing the motion data and the moving image data included in the moving image data with sound. More specifically, the synchronization processing unit 142 calculates the value of the cross-correlation function for the overlapping portion by shifting the other sound data by one unit time on the time axis with respect to one sound data, and the value is the maximum. If the value is taken, it is determined that the two sound data are synchronized.

If the communication state of the Internet 9 is stable, the data can be synchronized according to the timing at which the server device 14 receives the data.

(7) A configuration may be employed in which the smartphone 12 and the camera 13 work together to record sound, a moving image, and motion at the same time to generate content data. In this case, processing for generating content data by synchronizing motion data with sound and moving image data with sound is unnecessary.

(15) The elastic member 1119 is not limited to the string spring, and other types of springs, rubber members, or the like may be employed as the elastic member 1119.

(16) Instead of the motor 1115, another type of drive source such as a hydraulic cylinder may be used.

(17) The guide member 1118 is not limited to a linear guide. For example, a rail-shaped member (bearing) provided so as to extend vertically on the inner surface of the base portion 1111 so as to engage with a groove provided so as to extend vertically on the outer surface of the coupling base 1114. May be employed as the guide member 1118.

(18) The shape of the motion simulator 11 shown in FIGS. 7 to 11 is an example, and the shape may be variously changed.

(19) Although the camera 13 includes the function of the streaming server device, the streaming server device that transmits the moving image data with sound generated by the camera 13 to the server device 14 may be provided as a device different from the camera 13. Good. Alternatively, the smartphone 12 may receive the moving image data with sound from the camera 13 and transfer it to the server device 14.

(20) The virtual experience system 1 may not include the server device 14, and the control unit 117 may include the function of the server device 14.
