Method for controlling wearable device to output visual guide and electronic device performing the method

A method, performed by an electronic device, of controlling a wearable device, the method comprising:

• acquiring sensor data generated by a sensor of the wearable device;
• generating gait information of a user wearing the wearable device based on the sensor data;
• determining whether a position of a first leg of the user corresponds to a target position based on the sensor data;
• and
• when the position of the first leg corresponds to the target position, controlling the wearable device so that a first visual guide associated with the first leg is output at a first position based on the gait information.

A wearable device comprising:

• a base body configured to be positioned proximate a waist part of a user when the wearable device is worn on a body of the user;
• a waist support frame and a leg support frame configured to support at least a portion of the body of the user;
• a thigh fastener configured to attach the leg support frame to a thigh of the user;
• an inertial measurement unit (IMU), comprising a sensor, disposed in the base body;
• a driving module, comprising a motor and/or circuitry, configured to generate torque to be applied to a leg of the user, wherein the driving module is configured to be positioned between the waist support frame and the leg support frame;
• one or more optical output devices configured for outputting a visual guide on the ground;
• at least one processor comprising processing circuitry;
• and
• memory comprising one or more storage media storing instructions.
