Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a state estimation apparatus capable of properly estimating a state of an operation without depending on a position of a measurement object person.SOLUTION: A state estimation apparatus includes a triaxial angular velocity sensor 16a and a state estimation part 51. The triaxial angular velocity sensor 16a acquires an angular velocity around a rotational axis (grip axis) of a tennis racket when a tennis ball and the tennis racket are brought into contact with each other. The state estimation part 51 estimates a tennis ball contact position of the tennis racket on the basis of the acquired angular velocity.
