<P>PROBLEM TO BE SOLVED: To provide a sound volume control device, a sound volume control method, and a content reproduction system that can control reproduction sound volume of a content according to the state, action, etc., of a user who uses the content. <P>SOLUTION: The sound volume control device comprises a user information detection part, a tuning determination part, and a sound volume control part. The user information detection part detects vibrations, a sound, etc., that the user who uses the content generate as user information. The tuning determination part determines whether the user information is tuned to analytic information of the content. The sound volume control part performs processing for increasing content reproduction sound volume when the tuning determination part determines that the user information is tuned to the analytic information of the content. When it is determined that the user information is not tuned to the analytic information of the content, on the other hand, the sound volume control part performs processing for decreasing the reproduction sound volume of the content. <P>COPYRIGHT: (C)2013,JPO&INPIT |
