    Abstract: A wearable device, includes a motor, a motor driver circuit, a memory, a sensor, and a processor. The memory is configured to store resistance force generation setting information indicating a difference between a reference angle and each joint angle and a corresponding relationship between respective duty ratios. The processor is configured to obtain, using the sensor, a joint angle of a user and calculate a difference between the reference angle and the obtained joint angle. The processor is configured to obtain a duty ratio corresponding to the calculated difference according to the resistance force generation setting information. The processor is further configured to provide a control signal having the obtained duty ratio to the motor driver circuit to perform control such that a control state of the motor driver circuit is switched between a first control state and a second control state.

    Abstract: A wearable device may include a motor, a motor driver circuit, a frame connected to the motor, the frame to be worn on the body of the user to support the body, a processor configured to generate a control signal to control an electrical connection in the motor driver circuit, and a sensor configured to sense a body motion of the user. The processor is further configured to provide an exercise load through the frame according to a speed of the sensed body motion by controlling, based on the speed of the body motion, a changing ratio per time between a first control state in which the electrical connection in the motor driver circuit is a closed loop and a second control state in which the electrical connection in the motor driver circuit is an open loop.

    Abstract: A method and device for providing a resistance force to a user is disclosed. To provide a resistance force, the method includes measuring an angle of a joint of a user using a sensor of a wearable device, determining a resistance level for the joint based on the measured angle, determining a connection ratio of a motor driver circuit of the wearable device that corresponds to the resistance level, and controlling a motor based on the determined connection ratio of the motor driver circuit.
