Electronic device for providing various exercise experiences using exercise assistance device, wearable device, and control method for controlling exercise assistance device

An exercise assistance device comprising:

• a driving module, comprising a motor and/or circuitry, configured to generate torque;
• a torque transmission frame configured for transmitting the generated torque to a leg of a user;
• a thigh fastening member connected to the torque transmission frame and configured to connect the torque transmission frame to the leg of the user;
• a sensor module, comprising at least one sensor, configured to obtain sensor data comprising motion information of the user;
• and
• at least one processor comprising processing circuitry,
• wherein the at least one processor is individually and/or collectively configured to:
• based on a first user input comprising a selection of a piece of target exercise content, determine a piece of target exercise content to be executed from pieces of candidate exercise content using the exercise assistance device;
• based on a second user input comprising a selection of an exercise experience attribute associated with the piece of target exercise content, determine a torque profile of the piece of target exercise content;
• and
• based on the sensor data and the determined torque profile, control output torque of the motor, and
• wherein the torque profile is determined, according to the selected exercise experience attribute, based on at least one of a hip joint angle, a hip joint angular velocity, a hip joint angular acceleration of a user wearing the exercise assistance device, an angular difference between angles of both hip joints, an angular velocity difference between angular velocities of both hip joints, and an angular acceleration difference between angular accelerations of both hip joints of the user.

A control method of controlling an exercise assistance device, performed by an electronic device, the control method comprising:

• presenting pieces of candidate exercise content using the exercise assistance device;
• receiving a first user input comprising a selection of one of the pieces of candidate exercise content;
• based on the first user input, determining a piece of target exercise content to be executed;
• receiving a second user input comprising a selection of an exercise experience attribute associated with the piece of target exercise content;
• based on the second user input, determining a torque profile of the piece of target exercise content;
• and
• generating a control signal for driving the exercise assistance device according to the determined torque profile;
• and
• transmitting the control signal to the exercise assistance device, and wherein the torque profile is determine, according to the selected exercise experience attribute, based on at least one of a hip joint angle, a hip joint angular velocity, a hip joint angular acceleration of a user wearing the exercise assistance device, an angular difference between angles of both hip joints, an angular velocity difference between angular velocities of both hip joints, and an angular acceleration difference between angular accelerations of both hip joints of the user, determining the torque profile.
