First Claim
Patent Images
1. An estimation apparatus comprising:
- a first obtaining unit configured to obtain a value of an angular velocity around a predetermined rotation axis of a first object, the value of the angular velocity acquired in time when the first object and a second object come into contact with each other; and
an estimation unit configured to estimate a contact position of the second object on the first object based on the value of the angular velocity obtained by the first obtaining unit.

Abstract
A state estimation apparatus has a three-axis angular velocity sensor and a state estimation unit. The three-axis angular velocity sensor obtains a value of an angular velocity around a predetermined axis in a tennis racket when a tennis ball and the tennis racket come into contact. The state estimation unit estimates a contact position of the tennis ball on the tennis racket based on the obtained value of the angular velocity.
