A method includes defining a virtual space including a 360-degree moving image. The method includes playing back the 360-degree moving image. The method includes detecting a motion of a head-mounted device (HMD). The method includes defining a visual field in the 360-degree moving image based on the detected motion. The method includes detecting an emotion of a first user. The method includes comparing the detected emotion with a first condition. The method includes identifying a playback time of the 360-degree moving image at a timing of satisfaction of the first condition. The method includes identifying a direction indicated by the first user at the timing of satisfaction of the first condition. The method includes identifying a first region including a part of the 360-degree moving image corresponding to the identified direction. The method includes changing an evaluation value of the first region in response to satisfaction of the first condition.
