1. A head-mounted display device for enabling a user to simultaneously visually recognize a virtual image and an outside scene of the user'"'"'s environment, the head-mounted display device comprising:
- an image acquiring unit that acquires an image in a visual field direction of the user in a wearing state of the head-mounted display device, the image including an external object;
a warning-information generating unit that;
recognizes a specified part of the external object having an outer shape that coincides with a pattern stored in advance;
determines that the specified part of the external object poses a bodily danger to the user based on the recognition that the outer shape coincides with the pattern; and
generates warning information, which is an image for calling the user'"'"'s attention, on the basis of the image acquired by the image acquiring unit; and
an image display unit that causes the user to visually recognize the warning information as the virtual image,wherein the warning information generated by the warning-information generating unit includes a predetermined image that is arranged at the specified part of the external object, the predetermined image being an image formed by a figure having a shape that surrounds the outer shape of the specified part of the external object such that portions of the external object other than the specified part are not surrounded by the figure.

13. A control method for a head-mounted display device for enabling a user to simultaneously visually recognize a virtual image and an outside scene of the user'"'"'s environment, the control method comprising:
-
acquiring an image in a visual field direction of the user in a wearing state of the head-mounted display device, the image including an external object; recognizing a specified part of the external object having an outer shape that coincides with a pattern stored in advance; determining that the specified part of the external object poses a bodily danger to the user based on the recognition that the outer shape coincides with the pattern; generating warning information, which is an image for calling the user'"'"'s attention, on the basis of the acquired image; and causing the user to visually recognize the warning information as the virtual image, wherein the warning information includes a predetermined image that is arranged at the specified part of the external object, the predetermined image being an image formed by a figure having a shape that surrounds the outer shape of the specified part of the external object such that portions of the external object other than the specified part are not surrounded by the figure.

14. A head-mounted display device for enabling a user to simultaneously visually recognize a virtual image and an outside scene of the user'"'"'s environment, the head-mounted display device comprising:
-
a procedure managing unit that generates procedure information, which is an image representing content that the user should carry out, concerning a present procedure; an image acquiring unit that acquires an image in a visual field direction of the user in a wearing state of the head-mounted display device, the image including an external object; a warning-information generating unit that; recognizes a specified part of an external object having an outer shape that coincides with a pattern stored in advance; determines that the specified part of the external object poses a bodily danger to the user based on the recognition that the outer shape coincides with the pattern; and generates warning information, which is an image for calling the user'"'"'s attention, in the present procedure; and an image display unit that causes the user to visually recognize the procedure information and the warning information as the virtual image, wherein the procedure managing unit specifies, on the basis of the image acquired by the image acquiring unit, the present procedure from a plurality of procedures included in work, the procedure managing unit generates the procedure information for an overlapping area where a display area of the virtual image and an acquisition area of the image acquiring unit overlap each other in the image acquired by the image acquiring unit, the warning-information generating unit generates the warning information for the overlapping area, and the warning-information generating unit specifies, from the overlapping area in the image acquired by the image acquiring unit, that the specified part of the external object poses a bodily danger to the user and generates warning information in which a predetermined image is arranged at the specified part of the external object. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 27)
