Abstract
A head mounted display device includes an image display unit that allows a user to visually recognize image light based on image data as a virtual image and allows the user to visually recognize an outside scenery when worn on a head of the user, an imaging unit that images the outside scenery, and a control unit that, when an imaged image contains a mark image as an image of a specific mark, allows the user to visually recognize the specific virtual image associated with a combination of a type of the mark image and a shape of the mark image using the image display unit.
Claims12
A head mounted display device comprising:
- an image display that enables a user to visually recognize image light based on image data as a virtual image and enables the user to visually recognize an outside scenery when worn on a head of the user;
- an image sensor that images the outside scenery;
- and
- a controller that, when an imaged image contains a mark image as an image of a specific mark, enables the user to visually recognize the specific virtual image associated with a combination of a type of the mark image and a shape of the mark image using the image display,
- wherein, when the imaged image contains a plurality of mark images, the controller detects the specific virtual image associated with the combination of the mark image having the maximum size among the plurality of mark images and displays the detected specific virtual image using the image display without displaying other of the plurality of mark images,
- wherein the specific virtual image is a virtual image of a first direction instruction instructing the user to move in a predetermined direction, based on the positional relationship between the device and the specific mark, and
- wherein the controller hides the specific virtual image after being displayed and enables the user to visually recognize a second direction instruction when the distance between the device and the specific mark represented by the mark image becomes smaller than a predetermined value.

An image display system comprising:
- a plurality of specific marks;
- an image display that enables a user to visually recognize image light based on image data as a virtual image and enables the user to visually recognize an outside scenery when worn on a head of the user;
- an image sensor that images the outside scenery;
- and
- a controller that, when an imaged image contains the specific mark, enables the user to visually recognize the virtual image determined based on a type of the specific mark and a shape of an image of the imaged specific mark using the image display,
- wherein, when the imaged image contains a plurality of mark images, the controller detects the specific virtual image associated with the combination of the mark image having the maximum size among the plurality of mark images and displays the detected specific virtual image using the image display without displaying other of the plurality of mark images,
- wherein the specific virtual image is a virtual image of a first direction instruction instructing the user to move in a predetermined direction, based on the positional relationship between the device and the specific mark, and
- wherein the controller hides the specific virtual image after being displayed and enables the user to visually recognize a second direction instruction when the distance between the device and the specific mark represented by the mark image becomes smaller than a predetermined value.

A method of controlling a head mounted display device, the method comprising:
- imaging, by an image sensor, an image that contains a mark image as an image of a specific mark;
- enabling a user to visually recognize the specific virtual image associated with a combination of a type of the mark image and a shape of the mark image using an image display;
- when the imaged image contains a plurality of mark images, detecting the specific virtual image associated with the combination of the mark image having the maximum size among the plurality of mark images;
- displaying the detected specific virtual image using the image display without displaying other of the plurality of mark images,
- wherein the head mounted display device includes the image display that enables the user to visually recognize image light based on image data as a virtual image and enables the user to visually recognize an outside scenery when worn on a head of the user and an image sensor that images the outside scenery,
- wherein the specific virtual image is a virtual image of a first direction instruction instructing the user to move in a predetermined direction, based on the positional relationship between the device and the specific mark;
- and
- hiding the specific virtual image after being displayed and enabling the user to visually recognize a second direction instruction when the distance between the device and the specific mark represented by the mark image becomes smaller than a predetermined value.
