Abstract: A wearable device may include an actuator including a motor and/or circuitry, a sensor configured to generate motion data corresponding to a motion of a hand of a user, at least one processor configured to control the actuator, a cable connected to the actuator, and a body coupling component connected to the cable and connected or fixed to a body part of the user, wherein the processor is individually and/or collectively configured to estimate a position of the hand of the user based on the motion data corresponding to the motion of the hand of the user, determine a tension value to be applied to the cable at the position of the hand of the user based on the position of the hand of the user and a tension control model defined with respect to a surrounding space of the user, and control the actuator to generate tension at the determined tension value on the cable.

Abstract: A method of determining an arm posture of a user may include determining a distance from a first part of a body of the user to a second part of a lower arm of the user based on length information of a cable generated by a first sensor arranged on at least a part of the body of the user, determining a first rotation angle of the lower arm in a three-dimensional space based on rotation information generated by a second sensor attached to the second part, determining a second rotation angle of an upper arm in the three-dimensional space based on the distance from the first part to the second part and the first rotation angle of the lower arm, determining a position of the upper arm and a position of the lower arm in the three-dimensional space based on the first rotation angle of the lower arm and the second rotation angle of the upper arm; and determining the arm posture based on the position of the upper arm and the position of the lower arm.
