<P>PROBLEM TO BE SOLVED: To predict the speed of a tip of a playing tool from the measured acceleration of a player's hand. <P>SOLUTION: Provided are: an acceleration sensor 2 that is mounted on a player's hand to measure acceleration; a communication part 11 that receives the measured acceleration from the acceleration sensor 2 as acceleration information; an analyzing part 13 that calculates the acceleration of the tip of the playing tool that the player swings, on the basis of the acceleration information received by the communication part 11; and a display part 14 that displays the speed calculated by the analyzing part 13, wherein the acceleration sensor 2 measures acceleration in a first direction from the wrist on the back of the player's hand to the direction of the base of finger and acceleration in a second direction orthogonal to both directions substantially parallel to the first direction and the back of the player's left hand, and the analyzing part 13 calculates, based on the acceleration in the first direction and the acceleration in the second direction, the speed of the tip of the playing tool that the player swings. <P>COPYRIGHT: (C)2013,JPO&INPIT |
