A glasses-type wearable device providing an augmented reality guide and a method for controlling the same is provided. The glasses-type wearable device includes a communication circuit, a camera, and a processor configured to receive a second surrounding-image of an external electronic device connected with the glasses-type wearable device from the external electronic device through the communication module while obtaining a first surrounding-image of the glasses-type wearable device using the camera, identify a first task being performed by a user of the glasses-type wearable device using the first surrounding-image and a second task being performed by a user of the external electronic device using the second surrounding-image, identify a difference between a current progress status of the first task and second task, and control the communication circuit to provide an AR guide corresponding to the second task to the external electronic device, based on the identified difference in progress status.
