    Abstract: An electronic device performing a method of tracking a user's gaze of an electronic device and outputting an augmented reality (AR) image is provided. The metho includes outputting a first light which is a structured light at a first time point toward the user's eyes, outputting a second light at a second time point toward the user's eyes, acquiring a first image in response to the output of the first light at the first time point, acquiring a second image in response to the output of the second light at the second time point, synthesizing the first image and the second image to create a third image, calculating first coordinate values, which are coordinate values of pupils of the user's eyes on the basis of the third image; and detecting a gaze direction on the basis of the first coordinate values.

    Abstract: An electronic device is provided. The electronic device includes at least one processor, and a head-mounted display (HMD) device wirelessly connecting to the at least one processor. The at least one processor includes a first communication module, a light-emitting device, and a first processor for controlling the brightness of the light-emitting device based on a brightness adjustment signal received from the HMD device. The HMD device includes a second communication module, a sensor for measuring external illuminance, and a second processor for acquiring the external illuminance measured by the sensor, and, based on the obtained external illuminance, transmitting the brightness adjustment signal, for adjusting the brightness of the light-emitting device of the at least one processor, to the at least one processor by using the second communication module.

    Abstract: The electronic device includes a pad module and a main module. At least part of the patch module is attached to a user to obtain a bio-signal of the user. The pad module includes a first housing and a plurality of first electrodes disposed in the first housing. The main module is configured to record the bio-signal of the user that is transferred through the pad module. The main module includes a second housing that is coupled with the first housing in a first direction. The main module also includes a plurality of second electrodes disposed in the second housing. The plurality of second electrodes are configured to make electrical contact with the plurality of first electrodes. The main module further includes a plurality of magnetic bodies disposed in the second housing to correspond to positions of the plurality of second electrodes.
