Provided is a head mounted display (HMD) device that lets a user organize added information and thereby makes it possible to improve the ease with which the information can be perceived. A head mounted display device enables a user to visually recognize a virtual image overlaid on a scene. A control unit virtually sets a plurality of display zones, having different depth-direction positions, in front of the user; identifies a display zone being gazed at by the user, on the basis of gaze position information from a gaze position detection unit; drives a focus position adjusting unit so as to align the depth position of the identified display zone with the focus position of a virtual image of the displayed image; acquires, from a cloud server via a communication unit, image information indicating information associated with the identified display zone; and causes a display to display the display image corresponding to the acquired image information.
