## Abstract

The balance training apparatus includes: a moving cart capable of moving on a moving surface by driving a driving unit; a detection unit configured to detect a load received from a foot of a trainee who is standing on the moving cart; a calculation unit configured to calculate the center of gravity of loads of both feet of the trainee on a riding surface from, the load detected by the detection unit; a setting unit configured to set the center of gravity of the loads at which it is estimated that the trainee has maintained an upright state on the riding surface as a reference center of gravity; and an instruction controller configured to output an instruction of the orientation of the body to the trainee and an instruction to move the center of gravity to the trainee.

## Claims

### Claim 1

A balance training apparatus comprising:
a moving cart capable of moving on a moving surface by driving a driving unit:
a detection unit configured to detect a load received from a foot of a trainee who is standing on the moving cart;
a calculation unit configured to calculate a center of gravity of loads of both feet of the trainee on a riding surface from the load detected by the detection unit;
a setting unit configured to set the center of, gravity of the loads at which it is estimated that the trainee has maintained an upright state on the riding surface as a reference center of gravity; and
an instruction controller configured to output an instruction of an orientation of a body to the trainee and an instruction to move the center of gravity to the trainee,
wherein the calculation unit determines the orientation of the body of the trainee based on a change direction of the center of gravity of the loads from the reference center of gravity when the trainee has moved his/her center of gravity in accordance with the instruction from the instruction controller, and outputs an operation instruction to the driving unit when it is determined that a result of the determination is appropriate.

### Claim 2 (depends on 1)

The balance training apparatus according to claim 1, wherein the setting unit sets the reference center of gravity based on the center of gravity of the loads calculated by the calculation unit in a calibration operation that the trainee performs prior to trial of the training.

### Claim 3 (depends on 1)

The balance training apparatus according to claim 1, wherein
the instruction controller outputs a center of gravity moving instruction to the trainee who is in an upright state to cause the trainee to move one foot, and
the calculation unit outputs the operation instruction to the driving unit when a displacement direction of the center of gravity of the loads of the trainee from the reference center of gravity after the instruction for moving the center of gravity is a direction along a preset displacement direction.

### Claim 4 (depends on 1)

The balance training apparatus according to claim 1, wherein the calculation unit switches a front/back training mode in which a frontal direction of the body of the trainee matches a moving direction of the moving cart and a right/left training mode in which the frontal direction of the body of the trainee is substantially orthogonal to the moving direction of the moving cart based on an external instruction.

### Claim 5 (depends on 1)

The balance training apparatus according to claim 1, wherein the calculation unit instructs the instruction controller to display a position of the center of gravity of the loads of the trainee, and after it is determined that the center of gravity of the loads of the trainee remains in a preset measurement start position for a predetermined period of time, the calculation unit instructs the instruction controller to cause the trainee to move the center of gravity.

### Claim 6

A non-transitory computer readable medium storing a control program of a balance training apparatus in which a trainee who is standing on a moving cart that moves on a moving surface performs balance training, the control program causing a computer to execute the following steps:
a center of gravity calculation step for calculating the center of gravity of loads of both feet of the trainee on a riding surface from a load detected by a detection unit mounted on the moving cart;
a reference center of gravity setting step for setting the center of gravity of the loads at which it is estimated that the trainee has maintained an upright state on the riding surface as a reference center of gravity;
an instruction control step for outputting an instruction of an orientation of a body to the trainee and an instruction to move the center of gravity to the trainee; and
a control determination step for determining the orientation of the body of the trainee based on a change direction of the center of gravity of the loads from the reference center of gravity when the trainee has moved his/her center of gravity in the instruction output in the instruction control step and performing control to move the moving cart when it is determined that a result of the determination is appropriate.
