Wearable device and method of operating the wearable device

Abstract

The wearable device includes a motor, a motor driver circuit, a frame connected to the motor and worn on a user's body to support the body, a processor that generates a control signal for controlling an electrical connection relationship of the motor driver circuit, and a sensor that detects the user's body motion. The processor controls a time conversion rate between a first control state in which the electrical connection of the motor driver circuit is a closed loop and a second control state in which the electrical connection of the motor driver circuit is an open loop based on the detected body motion speed, thereby providing an exercise load according to the body motion speed via the frame.
