Abstract: When a sound event generated outside has been sensed while a specific function is executed and the sound event satisfies a specific condition, an HMD according to the present invention may provide a notification therefor to a user. More specifically, the HMD comprises: a display unit formed to output screen information; an acoustic output unit for outputting acoustic information; a microphone for sensing the sound event generated outside of the HMD in a state in which the acoustic information is output; a user input unit for receiving an input of a control command for controlling the display unit and the acoustic output unit; and a control unit for controlling the display unit to output a graphic object notifying of the generation of the sound event when the sound event sensed through the microphone satisfies a pre-configured condition, and activating the user input unit in order to change an output state of at least one of the screen information and the acoustic information while the graphic object is output.
