US 2026/0161138 A1 · SYSTEM FOR DETECTING DIRECTION OF MOVEMENT, WEARABLE ELECTRONIC DEVICE, AND METHOD FOR DETECTING DIRECTION OF MOVEMENT IN SAID SYSTEM AND SAID WEARABLE ELECTRONIC DEVICE

Abstract

A wearable electronic device is provided. The wearable device includes a sensor module, a location measurement module, a communication module, memory storing one or more computer programs, and one or more processors communicatively coupled to the sensor module, the location measurement module, the communication module, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the wearable electronic device to, when identifying execution of a location-based application, request an external wearable electronic device communication-connected through the communication module to calculate posture information about the external wearable electronic device, when identifying that a reception sensitivity of a location signal received from the location measurement module is equal to or less than a threshold level during detection of a movement direction of the wearable electronic device based on the location signal, request the posture information about the external wearable electronic device from the external wearable electronic device, and detect the movement direction of the wearable electronic device by applying the posture information received from the external wearable electronic device to pedestrian dead reckoning.
