Electronic device and wearable device for providing function for measuring amount of exercise and operation methods thereof

A wearable device for assisting a user in doing an exercise, comprising:

• a driving module, comprising circuitry, configured to generate torque to be applied to a body of the user;
• a support frame configured to support the body of the user when the wearable device is worn on the body of the user so that the generated torque can be applied to the body of the user;
• a sensor module, comprising a sensor, configured to obtain sensor data comprising movement information of the user of the wearable device;
• a communication module, comprising communication circuitry, configured to receive setting data on an exercise intensity selected by a user input from an electronic device, and transmit the sensor data to the electronic device;
• and
• a control module, comprising circuitry, configured to control the driving module based on the selected exercise intensity in the setting data,
• wherein the control module is configured to:
• control the communication module to transmit the sensor data to the electronic device to allow the electronic device to estimate an exercise amount of the user based on the sensor data and the selected exercise intensity, generate an exercise activity indicator comprising at least one graphic indicator for indicating the estimated exercise amount, and output a graphical user interface (GUI) in which the exercise activity indicator is displayed.

An operation method of an electronic device, the method comprising:

• providing a personalized target exercise amount for a user wearing a wearable device;
• receiving a user input that selects an exercise intensity to be applied to an exercise to be performed by the user;
• transmitting, to the wearable device, setting data on the exercise intensity selected by the user input;
• receiving, from the wearable device, sensor data comprising movement information obtained during the exercise of the user wearing the wearable device;
• estimating an exercise amount of the user based on the received sensor data and the selected exercise intensity;
• and
• outputting a graphical user interface (GUI) in which an exercise activity indicator comprising at least one graphic indicator for indicating the estimated exercise amount is displayed,
• wherein the at least one graphic indicator comprises:
• a first graphic indicator corresponding to a target exercise amount to be achieved by the user through the exercise;
• a second graphic indicator corresponding to an exercise amount achievement estimate that is achieved by the user doing the exercise without the selected exercise intensity being applied;
• and
• a third graphic indicator corresponding to an additional exercise amount achievement estimate that is achieved by the user doing the exercise with the selected exercise intensity being applied.
