Abstract:
1. A head-mounted display device that causes a user to recognize a virtual image in a state in which the head-mounted display device is mounted on a head of the user, the head-mounted display device comprising: an image-light generating unit for right eye that generates image light from image data for right eye corresponding to a right eye of the user and emits the image light; an image-light generating unit for left eye that generates image light from image data for left eye corresponding to a left eye of the user and emits the image light; a pair of light guide units that guide the image lights, which are emitted from the image-light generating unit for right eye and the image-light generating unit for left eye, to the left and right eyes of the user; and a display control unit that transmits a plurality of separate control signals for separately controlling the emission of the image lights respectively to the image-light generating unit for right eye and the image-light generating unit for left eye, wherein the display control unit transitions, according to a condition set in advance, the head-mounted display device to a power-saving start for causing one of the image-light generating unit for right eye and the image-light generating unit for left eye to stop the emission of the image light and causing the other to execute the emission of the image light, the head-mounted display device further comprising a selection receiving unit that receives, from the user, a selection of one of the image-light generating unit for right eye and the image-light generating unit for left eye, selecting the one of the image-light generating unit for right eye and the image-light generating unit for left eye to stop emission of the image light by the display control unit, and in the power saving state, the display control unit directly and alternately switched between a first state and a second state after every elapse of a predetermined period of time, the first state causing one of the image-light generating unit for right eye and the image-light generating unit for left eye to stop the emission of the image light and causing the other to execute the emission of the image light, and the second state causing one of the image-light generating unit for right eye and image-light generating unit for left eye to execute the emission of the image light and causing the other to stop the emission of the image light.
