1. An electronic device comprising:
a controller device; and
a head-mounted display (HMD) device wirelessly connected to the controller device,
wherein the controller device comprises:
a first communication circuit,
a light emitting element, and
a first processor configured to control brightness of the light emitting element based on a brightness adjustment signal received from the HMD device,
wherein the HMD device comprises:
a second communication circuit,
a memory,
a sensor configured to measure external illuminance, and
a second processor configured to:
obtain external illuminance measured by the sensor, and
transmit a brightness adjustment signal for adjusting brightness of the light emitting element of the controller device to the controller device using the second communication circuit based on the obtained external illuminance,
wherein an initial brightness value of the light emitting element that distinguishes the controller device from other objects according to an arbitrary external illuminance is stored in the memory, and
wherein the obtaining of the external illuminance prior to the transmission of the brightness adjustment signal for adjusting brightness of the light emitting element is based on the initial brightness value of the light emitting element.
