Patent number: RE47948Abstract: By allowing the movement of a user to affect the playback of content, the entertainment characteristic or uplifting spirits derived from content playback itself can be enhanced. The timing at which the user places his/her foot on the ground while walking or the timing at which the user shakes or changes from swinging in one direction to swinging to another direction is detected. Then, content, such as a music piece or moving pictures, is played back by allowing the timing of beats or bars of the music piece or the timing of scene changes or cut changes of the moving pictures to be synchronized with the timing of the movement of the user.Type: GrantFiled: January 21, 2015Date of Patent: April 14, 2020Assignee: Sony CorporationInventors: Motoyuki Takai, Toshiro Terauchi, Yoichiro Sako, Yasushi Miyajima, Kosei Yamashita, Makoto Inoue, Masamichi Asukai, Katsuya Shirai, Kenichi Makino
