<P>PROBLEM TO BE SOLVED: To provide an input device that generates operation input in line with an actual drum performance. <P>SOLUTION: Stick parts 20-1 and 20-2 respectively generate data on acceleration that changes according to a user's stick operation, and sends the data wirelessly, and then, a body part 10 receives the data. The body part 10 executes: a step for using acceleration data for multiple past samples including the acceleration data acquired this time to calculate a latest moving average; a step for extracting a gravity direction viewed from each of the stick parts 20-1 and 20-2, based on the calculated moving average; a step for determining whether or not percussions (rapid change in the acceleration) in a mutually different direction to the extracted gravity direction are detected simultaneously from the stick parts 20-1 and 20-2, that is, whether or not a cross stick technique of striking sticks is conducted; and a step for instructing to produce eigentone (hit sound) of striking sticks when the cross stick technique is conducted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
