ELECTRONIC DEVICE USING EXTERNAL DEVICE AND OPERATING METHOD THEREOF

An electronic device according to various embodiments of the present disclosure may include: a sensor module; a memory; and a processor, where the memory may store instructions that cause the processor to: estimate a field of view (FOV) of a user by using a sensor included in the wireless headset; estimating an FOV of the electronic device by using the sensor module; comparing the estimated FOV of the user with the estimated FOV of the electronic device; determining whether the user watches a screen of the electronic device based on a comparison result; identifying a gaze of the user if it is determined that the user gazes the screen of the electronic device; and performing a specific function based on the recognized gaze of the user. 根据本公开的各种实施例的电子装置可以包括：传感器模块；存储器；以及处理器，其中存储器可以存储有指令，该指令使得处理器：通过使用无线耳机中包括的传感器来估计用户的视场(FOV)；通过使用传感器模块来估计电子装置的FOV；将所估计的用户的FOV与所估计的电子装置的FOV进行比较；基于比较结果来确定用户是否注视电子装置的屏幕；在确定用户注视电子装置的屏幕的情况下识别用户的注视；以及基于所识别的用户的注视来执行特定的功能。
