PROBLEM TO BE SOLVED: To easily and quickly measure a carry according to a speed of a virtual object caused by a throwing action and a kicking action without actually throwing and kicking an object such as a ball in a motional data estimating device to measure a speed of a thrown ball speed and a kicked ball speed in, for example, a ball game. SOLUTION: A watch body 11 is installed on a wrist of the hand more skilful than the other, and when a ball throwing action is performed, after right handedness/left-handedness is discriminated by inclination switches 10a and 10b, acceleration caused by this ball throwing action detected by an acceleration sensor 12 is detected, and a ball throwing speed is calculated on the basis of this acceleration, and an arrival distance (a carry) is calculated and displayed. Therefore, there is no need for a user to throw an actual ball or for a third person to measure a ball speed of a thrown ball by a measure, and the carry according to a ball throwing speed can be measured by the user by herhimself. |
