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;
a control unit that is connected to the image display unit and controls image display by the image display unit, the control unit including an operation surface that controls an operation of the head-mounted display device; and
a direction determining unit that determines whether the user faces the operation surface of the control unit based on movement of the head-mounted display device on a head of the user wearing the head-mounted display device exceeding a fixed amount, whereinresponsive to the movement of the head-mounted display device on the head of the user exceeding a fixed amount, 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, andwhen the direction determining unit determines that the movement of the head-mounted display device on the head of the user exceeds the fixed amount, 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.

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.

18. 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) using the operation surface to control an operation of the head-mounted display device; (c) determining whether the user faces the operation surface to control the operation of the head-mounted display device for (b), based on movement of the head-mounted display device on a head of the user wearing the head-mounted display device exceeding a fixed amount; and (d) adjusting, responsive to the movement of the head-mounted display device on the head of the user exceeding the fixed amount, 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.

19. 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, when movement of the head-mounted display device on a head of a user wearing the head-mounted display device exceeds a fixed amount; and (d) adjusting, when the movement of the head-mounted display device 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.
