HEAD-MOUNTED DISPLAY DEVICE AND CONTROL METHOD FOR THE HEAD-MOUNTED DISPLAY DEVICE
First Claim
1. A head-mounted display device comprising:
- an image display unit including an image-light generating unit that generates image light representing an image and emits the image light and a light guide unit that guides the emitted image light to an eye of a user, the image display unit being for causing the user to visually recognize a virtual image; and
a control unit that is connected to the image display unit and controls image display by the image display unit, whereinwhen it is assumed that the user shifts the user'"'"'s attention from the virtual image, the control unit adjusts luminance of the image-light generating unit or adjusts the image light generated by the image-light generating unit to reduce visibility of the virtual image.

Abstract
A head-mounted display device includes: an image display unit including an image-light generating unit that generates image light representing an image and emits the image light and a light guide unit that guides the emitted image light to the eye of a user, the image display unit being for causing the user to visually recognize a virtual image; and a control unit that includes an operation surface, is connected to the image display unit, and controls image display by the image display unit. When it is assumed that the user shifts the user'"'"'s attention from the virtual image, the control unit adjusts the luminance of the image-light generating unit or adjusts the image light generated by the image-light generating unit to reduce the visibility of the virtual image.

19. A control method for a head-mounted display device including an operation surface, the control method comprising:
-
(a) causing, using an image-light generating unit that generates image light representing an image and emits the image light and a light guide unit that guides the emitted image light to an eye of a user, the user to visually recognize a virtual image; (b) controlling image display in (a); (c) determining whether the user faces the operation surface in order for (b); and (d) adjusting, when it is assumed that the user faces the operation surface in order for (b), luminance of the image-light generating unit or adjusting the image light generated by the image-light generating unit to reduce visibility of the virtual image.

20. A control method for a head-mounted display device, comprising:
-
(a) causing, using an image-light generating unit that generates image light representing an image and emits the image light and a light guide unit that guides the emitted image light to an eye of a user, the user to visually recognize a virtual image; (b) controlling image display in (a); (c) acquiring change information indicating a change in a direction of the head-mounted display device and detecting, using the change information, movement of a head exceeding a fixed amount of the user wearing the head-mounted display device; and (d) adjusting, when the movement of the head exceeding the fixed amount is detected, luminance of the image-light generating unit or adjusting the image light generated by the image-light generating unit to reduce visibility of the virtual image.
