Abstract: In a case where operations to a player character are restricted and a virtual camera is controlled according to event data, motion of the user's head, which is detected by an HMD 300, is reflected on the direction of the virtual camera that is set based on the event data. As a result, even in a situation where the user cannot operate the player character as he/she wants, images displayed on the HMD 300 move together with motion of the head. Therefore, it is possible to reduce occurrence of simulator sickness.

Abstract: A distance measuring unit 331 measures a distance of a path of sound based on the number of map units between the map unit where a sound source is located and the map unit where a player character is located. An effect unit 332 attenuates the volume of a game sound based on the distance calculated by the distance measuring unit 331. Thereby, it is possible to attenuate the volume level of the sound effect depending on the distance where the sound is transmitted, even if the sound comes around an object obstructing sound.
