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 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, the control unit including an operation surface that controls an operation of the head-mounted display device based on finger operation by the user detected on the operation surface; and
a direction determining unit that determines whether the user faces the operation surface of the control unit, whereinif the direction determination unit determines that the user faces the operation surface, 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.

8. A control method for a head-mounted display device including an operation surface, the control method comprising:
-
(a) causing a user to visually recognize a virtual image by 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 the user; (b) controlling image display in (a) by using the operation surface to control an operation of the head-mounted display device based on finger operation by the user detected on the operation surface; (c) determining, by a direction determination unit, whether the user faces the operation surface to control the operation of the head-mounted display device; and (d) if the direction determination unit determines that the user faces the operation surface, adjusting 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. - View Dependent Claims (9, 10, 11, 12, 13, 14, 17, 18)
