AI summary

A vibration signal for vibrating a vibration apparatus is generated, and data obtained by encoding amplitude modulation information indicating a change in an amplitude and/or frequency modulation information indicating a change in a frequency are acquired. Then, the acquired data is decoded, and the vibration signal is generated using the decoded amplitude modulation information and/or frequency modulation information.
