Samsung patents wearable that adjusts walking force while you test walk

1. A method of adjusting a control parameter value performed by a wearable device, the method comprising: outputting a first torque value to a driver circuit configured to control the wearable device to apply a force to a portion of a body of a user while the user is wearing the wearable device, the first torque value being determined based on a first value of a control parameter, and the control parameter including at least one of magnitude information, output timing information, and sensitivity information; obtaining a first angular velocity of a first joint in the body of the user in association with the output of the first torque value; determining, based on the first angular velocity, a second value of the control parameter to change the first angular velocity of the first joint; outputting a second torque value to the driver circuit, the second torque value being determined based on the second value of the control parameter; obtaining a second angular velocity of the first joint in the body of the user in association with the output of the second torque value; and determining a final value of the control parameter based on the second value of the control parameter, wherein the determination of the final value is further based on a termination condition on optimization of the control parameter being satisfied after the second angular velocity is obtained, and wherein the determining of the second value of the control parameter to change the first angular velocity of the first joint comprises: re-determining the second value of the control parameter to change the first angular velocity of the first joint, based on the termination condition being not satisfied after the second angular velocity is obtained, wherein the termination condition comprises at least one of whether a number of times of adjusting a value of the control parameter corresponds to a threshold number of adjustment, whether a number of strides of the user corresponds to a threshold number of strides, and a passage of time for adjusting the value of the control parameter corresponds to a threshold time, and wherein the determining of the second value of the control parameter comprises: calculating a first gait agility value representing gait agility of the user based on the first angular velocity of the first joint in the body of the user obtained in association with the output of the first torque value; and determining the second value of the control parameter to change the gait agility of the user.
