Abstract
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.
Claims22
A display device that receives an output of an inertial sensor associated with a golf club held by a user, comprising:
- a processor that determines from the output of the inertial sensor a first plane including (a) a first straight line that extends in an extending direction of a shaft portion of the golf club, and (b) a second straight line showing a ball hitting direction, and determines a second plane based on a user's static position holding the golf club, a ball-hitting position and a ball hitting direction;
- and
- a display that displays on a screen an image of the first plane, the second plane and the golf club simultaneously,
- wherein the first and second planes are visually displayed in a three-dimensional space, and wherein the second plane is determined in three dimensions based upon coordinates of a shoulder of the user.
A display device that receives an output of an inertial sensor associated with a sporting gear held by a user, comprising:
- a processor that determines from the output of the inertial sensor:
- (i) a first plane including (a) a first straight line that extends in an extending direction of a shaft portion of the sporting gear, and (b) a second straight line showing a ball hitting direction, and (ii) a second plane including (1) a third straight line connecting a neck or shoulder of the user and a ball hitting position of the user and (2) the second straight line showing the ball hitting direction;
- and
- a display that displays an image of the first plane, the second plane and the sporting gear simultaneously,
- wherein the first and second planes are visually displayed in a three-dimensional space, and wherein the second plane is determined in three dimensions based upon coordinates of a shoulder of the user.
A display method that uses an output of an inertial sensor associated with a golf club held by a user, comprising:
- determining with a processor, from the output of the inertial sensor, a first plane including (a) a first straight line that extends in an extending direction of a shaft portion of the golf club, and (b) a second straight line showing a ball hitting direction, and determining a second plane based on a user's static position holding the golf club, a ball-hitting position and a ball hitting direction;
- and
- displaying on a screen an image of the first plane, the second plane and the golf club simultaneously,
- wherein the first and second planes are visually displayed in a three-dimensional space, and wherein the second plane is determined in three dimensions based upon coordinates of a shoulder of the user.
A display method that uses an output of an inertial sensor associated with a sporting gear held by a user, comprising:
- determining with a processor, from the output of the inertial sensor, (i) a first plane including (a) a first straight line that extends in an extending direction of a shaft portion of the sporting gear and (b) a second straight line showing a ball hitting direction of the sporting gear, (ii) a second plane including (1) a third straight line connecting a neck or shoulder of a subject and a ball hitting position and (2) the second straight line;
- and
- displaying on a display an image of the first plane, the second plane and the sporting gear simultaneously,
- wherein the first and second planes are visually displayed in a three-dimensional space, and wherein the second plane is determined in three dimensions based upon coordinates of a shoulder of the user.
