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.
