A motion analysis device includes a calculation unit which specifies a first imaginary plane, that is, a shaft plane formed by a first line segment representing a direction in which a shaft part of a sporting gear in a static posture extends and a second line segment representing a ball hitting direction, with the use of an output from an inertial sensor.

Motion analysis method and motion analysis device

A motion analysis method includes calculating a change in an amount of inertia of a region attached with an inertial sensor during a swing using an output of the inertial sensor, and identifying a maximum value of the amount of inertia during the swing to compare the maximum value and the amount of inertia at an impact with each other. A deceleration timing during the swing of the region (the grip of the sporting equipment) attached with the inertial sensor is identified, and the quality of the swing can be evaluated.

A motion analysis apparatus includes an impact analysis unit that specifies a hitting direction of an exercise appliance during impact and a speed of the exercise appliance during the impact by using an output signal from an inertial sensor, and a display unit that displays the hitting direction and the speed in a coordinate system in which a hitting target direction is set.

A motion analysis device that obtains a relation between a movement direction of a ball hitting surface of an exercise tool at a time of starting a swing and a posture of the ball hitting surface at the time of impact during the swing by using output of an inertial sensor.

A motion analysis method includes: specifying a first axis along a longitudinal direction of a shaft of a golf club when a user is at a standstill using an output of a sensor unit; and estimating a prescribed position between head and chest of the user when the user is at a standstill using the output of the sensor unit and body information of the user, and specifying a second axis which connects the estimated prescribed position and a hitting position.

Motion analysis method, program, and motion analysis device

A motion analysis method includes: specifying plural operations included in a motion operation using an output from an inertial sensor; calculating an operating time of each of the plural operations; adjusting a time axis of each operating time; and outputting operation information of the operation based on the adjusted time axis.

Motion analysis method and motion analysis apparatus

A motion analyzing apparatus includes a first calculation unit that calculates a position of a first line segment representing a direction in which a rod-like part of a sporting tool extends in a stationary state, a second calculation unit that calculates the position of the first line segment at hitting, and a third calculation unit that specifies a virtual plane formed by the first line segment in the stationary state and a second line segment representing a ball hitting direction, wherein a relation between the virtual plane and the first line segment at the hitting is compared.

Motion analyzing apparatus and motion analyzing program

A motion analysis device has a determination unit which uses an output from an inertial sensor mounted on at least one of a subject and a tool operated by the subject, to determine a dominant hand of the subject in a swing. The determination unit can determine the dominant hand on the basis of the sign of angular velocity or acceleration from the inertial sensor. A calculation unit which calculates motion analysis information in a swing, using an output from the inertial sensor can add dominant hand information from the determination unit to the motion analysis information. The motion analysis device can include a coincidence determination unit which determines that a first subject and a second subject have different dominant hands, and an inverted image generation unit which inverts first motion analysis information in the case of no coincidence.
