Abstract: An electronic device is provided. The electronic device includes a plurality of antennas to communicate with an external electronic device and at least one processor operatively connected to the plurality of antennas. The processor is configured to detect a tracking start event using an external magnetic material positioned at a location adjacent to the electronic device, to track a location of the external electronic device using the plurality of antennas and, while the tracking is performed, to obtain a height value of the external electronic device when an angle between the electronic device and the external electronic device is a specified angle. The processor is further configured to change a specified condition based on the obtained height value, to detect a tracking end event based on the specified condition, and to change an operating mode associated with the electronic device in response to detecting the tracking end event.

Abstract: Provided are an electronic device and an operation method thereof. The electronic device may include: first and second antennas to receive a signal output by an external electronic device; a communication circuit configured to control the first antenna and the second antenna; and a processor. The processor may be configured to: receive the signal through the first antenna and the second antenna; measure a first distance between the first antenna and the external electronic device using the signal received by the first antenna; measure a second distance between the second antenna and the external electronic device using the signal received by the second antenna; determine a movement direction of the external electronic device based on a change in a difference between the first distance and the second distance; and perform a preset operation corresponding to the movement direction of the external electronic device. Other embodiments are also possible.
