Abstract

In an information display system, an information apparatus includes a target information storage section that stores target information to be published by the information apparatus and an extraction section that extracts the target information from the target information storage section on the basis of user information that is information regarding a user of a head mounted display device, and the head mounted display device includes an information generating section that generates information for additional presentation for providing the augmented reality to the user using the target information acquired from the information apparatus and an image display section that enables the user to view the generated information for additional presentation as a virtual image.

Claims

1. An information display system, comprising:

an information apparatus; and

a head mounted display device that enables a user to view a virtual image,

wherein the information apparatus includes;

a target information storage section that stores target information to be published by the information apparatus;

an extraction section that extracts the target information from the target information storage section on the basis of user information that is information regarding the user of the head mounted display device; and

a transmission section that transmits the extracted target information to the head mounted display device, and

the head mounted display device includes;

an information acquisition section that transmits the user information to the information apparatus and acquires the target information from the information apparatus;

an information generating section that generates information for additional presentation for providing augmented reality to the user using the acquired target information; and

an image display section that enables the user to view the generated information for additional presentation as the virtual image.

2. The information display system according to claim 1,

wherein extraction permission conditions that are conditions when extracting the target information are stored in the target information storage section so as to match the target information, and

the extraction section extracts the target information when the user information received from the head mounted display device satisfies the extraction permission conditions.

3. The information display system according to claim 1,

wherein at least one of an account name set by the user, authentication information set by the user, an e-mail address of the user, a network address of the head mounted display device, a MAC address of the head mounted display device, an account name provided from a provider of a service used by the user, and authentication information provided from the provider of the service used by the user is included in the user information.

4. The information display system according to claim 2,

wherein, in the information apparatus, order information for determining a display order of the target information is further stored in the target information storage section so as to match the target information, the extraction section extracts the order information from the target information storage section together with the target information, and the transmission section transmits the extracted target information and the extracted order information to the head mounted display device, and

the information generating section of the head mounted display device generates the information for additional presentation by superimposing the target information in order according to the order information when a plurality of pieces of the target information are received.

5. The information display system according to claim 1,

wherein the information apparatus further includes:

an update permission condition storage section that stores update permission conditions for allowing updating of the target information storage section; and

an update section that, when received information that has been received from the head mounted display device satisfies the update permission conditions, updates the target information storage section using the received information, and

the head mounted display device further includes an update request section that transmits information for updating the target information storage section to the information apparatus.

6. The information display system according to claim 5,

wherein, in the information apparatus, the limited area information specifying a limited area to limit updating of the target information storage section is stored in the update permission condition storage section of the information apparatus so as to match the update permission conditions, and the update section acquires the limited area information corresponding to current position information of the head mounted display device, which is included in the received information, and updates the target information storage section using the received information when the received information satisfies the update permission conditions matched with the acquired limited area information, and

the update request section of the head mounted display device transmits the current position information indicating a current position of the head mounted display device together with information for updating the target information storage section.

7. The information display system according to claim 5,

wherein at least one of conditions specifying the user for whom updating of the target information storage section is allowed, conditions specifying update date and time of the target information storage section, and conditions indicating that updating of the target information storage section is not allowed is included in the update permission conditions.

8. An information display method using an information apparatus and a head mounted display device that enables a user to view a virtual image, comprising:

(a) making the head mounted display device transmit user information, which is information regarding the user of the head mounted display device, to the information apparatus;

(b) making the information apparatus extract target information, which is to be published by the information apparatus, on the basis of the received user information;

(c) making the information apparatus transmit the extracted target information to the head mounted display device;

(d) making the head mounted display device acquire the target information from the information apparatus;

(e) generating information for additional presentation for providing augmented reality to the user using the acquired target information; and

(f) making the generated information for additional presentation be viewed as the virtual image by the user.

9. A head mounted display device that enables a user to view a virtual image, comprising:

an information acquisition section that acquires target information that is information extracted on the basis of user information that is information regarding the user of the head mounted display device;

an information generating section that generates information for additional presentation for providing augmented reality to the user using the acquired target information; and

an image display section that enables the user to view the generated information for additional presentation as the virtual image.

10. A head mounted display device that enables a user to view a virtual image, comprising:

a target information storage section that stores target information to be published by the head mounted display device;

an extraction section that extracts the target information from the target information storage section on the basis of user information that is information regarding the user;

an information generating section that generates information for additional presentation for providing augmented reality to the user using the extracted target information; and

an image display section that enables the user to view the generated information for additional presentation as the virtual image.
