Patent number: 5955692Abstract: Data representing the actual performance presented by a player is analyzed on the basis of given model performance data. Data of the virtual performance played by a virtual competitor is generated in accordance with the analysis result. Automatic performance based on the virtual performance data enables the player to compare his/her performance with the performance of the virtual competitor. Thus, the player can compete with the virtual competitor or compare his/her musical technique with that of the virtual performer even if the player practices the performance alone.Type: GrantFiled: June 8, 1998Date of Patent: September 21, 1999Assignee: Casio Computer Co., Ltd.Inventor: Ryutaro Hayashi
