<p>PROBLEM TO BE SOLVED: To enable notification to a user even when a reproduction device such as a general video DVD, and a TV monitor are used.SOLUTION: A motion ID and timing information recorded as an acoustic watermark in a DVD, etc. are decoded by an acoustic watermark decode part 40. An operation determination part 20 determines a motion ID based on results of detection by motion sensors 10 and 111 of a host 100 attached to a user's body, and a first slave 110a, etc. respectively, and the information in a motion library 70. In the motion library 70, the information indicating a movement content is assigned to a plurality of regions where an operation is performed and is stored as one set, and the motion ID is associated with each set on a one-to-one basis, and stored. A timing operation determination part 50 determines the matching of the motion ID after the decode and the motion ID of the determination result at a timing that the timing information after the decode indicates. A feedback generation part 60 generates a sound, etc. based on the determination result.</p> |
