Abstract

A wearable device and an exercise support method performed by the wearable device are disclosed. The exercise support method includes receiving exercise setting information associated with a lower body muscle that is selected by a user input, determining a torque profile to be applied to the wearable device based on the received exercise setting information, and operating an actuator of the wearable device based on the determined torque profile.

First claim

What is claimed is:

1. An exercise support method performed by a wearable device, comprising:
receiving, from a remote controller, exercise setting information comprising information on a lower body muscle; and
controlling an output of a resistance torque from an actuator of the wearable device based on the exercise setting information,
wherein the controlling of the output of the resistance torque comprises:
outputting the resistance torque to hinder a movement of a user in a time interval in which the lower body muscle is activated in an exercise of the user.

2. The exercise support method of claim 1 , further comprising:
determining a torque profile to apply to the wearable device based on the received exercise setting information,
wherein the controlling of the output of the resistance torque comprises:
controlling the output of the resistance based on the determined torque profile.

3. The exercise support method of claim 2 , wherein the determining of the torque profile comprises:
determining one or more gait segments corresponding to the lower body muscle among a plurality of gait segments within a gait phase; and
determining the torque profile such that the resistance torque is applied in the determined one or more gait segments.

4. The exercise support method of claim 2 , wherein the determining of the torque profile comprises:
determining the torque profile such that an assistance torque that supports a leg movement of the user is output in a first time interval and the resistance torque that hinders the leg movement of the user is output in a second time interval.

5. The exercise support method of claim 1 , wherein the exercise setting information further comprises information on an exercise intensity or an entire exercise time for the lower body muscle.

6. A wearable device comprising:
an actuator; and
a controller, comprising processing circuitry, configured to:
receive, from a remote controller, exercise setting information comprising information on a lower body muscle,
control the actuator to output a resistance torque based on the exercise setting information, and
control the actuator to output the resistance torque to hinder a movement of a user in a time interval in which the lower body muscle is activated in an exercise of the user.

7. The wearable device of claim 6 , wherein the controller is further configured to:
determine a torque profile to apply to the wearable device based on the received exercise setting information, and
control the output of the resistance based on the determined torque profile.

8. The wearable device of claim 7 , wherein the controller is further configured to:
determine one or more gait segments corresponding to the selected lower body muscle among a plurality of gait segments within a gait phase, and
determine the torque profile such that the resistance torque is applied in the determined one or more gait segments.

9. The wearable device of claim 7 , wherein the controller is further configured to:
determine the torque profile such that an assistance torque that supports a leg movement of the user is output in a first time interval and the resistance torque that hinders the leg movement of the user is output in a second time interval.

10. The wearable device of claim 6 , wherein the exercise setting information further comprises information on an exercise intensity and/or an entire exercise time for the lower body muscle.

11. An exercise support method performed by at least a remote controller, comprising:
the remote controller receiving, via a user interface, a user input indicating a lower body muscle selected by a user;
generating exercise setting information comprising information on the selected lower body muscle; and
the remote controller transmitting, to a wearable device, the exercise setting information so that the wearable device can output a resistance torque to hinder a movement of the user based on the exercise setting information.

12. The exercise support method of claim 11 , wherein, in response to receiving of the exercise setting information, the wearable device determines a torque profile to apply to the wearable device based on the exercise setting information and controls the output of the resistance based on the determined torque profile.

13. The exercise support method of claim 12 , wherein the torque profile is determined at least by:
determining one or more gait segments corresponding to the selected lower body muscle among a plurality of gait segments within a gait phase; and
determining the torque profile such that the resistance torque is applied in the determined one or more gait segments.

14. The exercise support method of claim 11 , wherein the exercise setting information further comprises information on an exercise intensity and/or an entire exercise time for the selected lower body muscle.

15. The exercise support method of claim 3 , wherein the determining of the torque profile comprises:
setting the torque profile such that the resistance torque is not output in the other ones of the plurality of gait segments within the gait phase that do not correspond to the selected at least one lower body muscle.

16. The wearable device of claim 8 , wherein the controller is further configured to:
set the torque profile such that the resistance torque is not output in the other ones of the plurality of gait segments within the gait phase that do not correspond to the selected at least one lower body muscle.

17. A non-transitory computer-readable medium comprising computer readable instructions that, when executed by a computer, cause the computer to perform the exercise support method of claim 1 .

18. A non-transitory computer-readable medium comprising computer readable instructions that, when executed by a computer, cause the computer to perform the exercise support method of claim 11 .
