Abstract

There are provided an augmented reality contents providing apparatus based on a Web information structure including: an HTML document that includes a URI setting unit setting a uniform resource identifier (URI) corresponding to a point of interest (POI), a POI processing unit collecting attribute information from a target terminal and identifying the POI by using the collected attribute information, a virtual object processing unit that matches a virtual object associated with the URI to the identified POI; and a 3D browser engine used for setting coordinates on the 3D physical space such that the POI and the virtual object are displayed in a 3D virtual space through a Web browser of the target terminal, analyzing video information of the POI and the virtual object based on the set coordinates, and providing the target terminal the analyzed video information.

Claims

1. An augmented reality contents providing apparatus based on a Web information structure comprising:

an HTML document that includes a URI setting unit setting a uniform resource identifier (URI) corresponding to a point of interest (POI) in a 3D physical space, a POI processing unit collecting attribute information from a target terminal and identifying the POI by using the collected attribute information, a virtual object processing unit that matches a virtual object associated with the URI to the identified POI; and

a 3D browser engine used for setting coordinates on the 3D physical space such that the POI and the virtual object are displayed in a 3D virtual space through a Web browser of the target terminal, analyzing video information of the POI and the virtual object based on the set coordinates, and providing the target terminal the analyzed video information.

2. The augmented reality contents providing apparatus based on a Web information structure according to claim 1, wherein the virtual object includes at least one of a text, an image, a moving image, and an animation to be displayed on the target terminal together with the POI.

3. The augmented reality contents providing apparatus based on a Web information structure according to claim 1, wherein the POI processing unit includes a first application code that identifies the POI by using at least one of GPS information, inertial sensor information, visual sensor information, and RFID tag information as the attribute information.

4. The augmented reality contents providing apparatus based on a Web information structure according to claim 1, wherein the virtual object processing unit performs matching such that the virtual object is located to overlap the identified POI.

5. The augmented reality contents providing apparatus based on a Web information structure according to claim 4, wherein the virtual object processing unit includes a second application code that applies at least one of rotation, scaling, and inclination to the virtual object with a location of the POI set as a reference so as to be located on the POI.

6. The augmented reality contents providing apparatus based on a Web information structure according to claim 5, wherein the second application code locates the virtual object on the POI by using a style sheet representing a 3D space.

7. The augmented reality contents providing apparatus based on a Web information structure according to claim 1, further comprising an event managing unit that manages a touch event for the virtual object,

wherein the virtual object processing unit executes a touched virtual object in response to the touch event for the virtual object.

8. The augmented reality contents providing apparatus based on a Web information structure according to claim 7, wherein the virtual object is a moving image or music information.

9. The augmented reality contents providing apparatus based on a Web information structure according to claim 1, further comprising an event managing unit that manages at least one of a touch event, a tracker event, a place event, and a POI event.

10. The augmented reality contents providing apparatus based on a Web information structure according to claim 1, further comprising the target terminal,

wherein the target terminal reads the HTML document by using a Web browser.

11. The augmented reality contents providing apparatus based on a Web information structure according to claim 10,

wherein the target terminal includes a camera and a display,

wherein the POI and a peripheral environment of the POI are photographed by the camera, and

wherein the display matches the virtual object to the photographed POI so as to be displayed through the Web browser.

12. A method of providing augmented reality contents based on a Web information structure, the method comprising:

generating an HTML document that includes an URI setting unit setting a uniform resource identifier (URI) corresponding to a point of interest (POI) in a 3D physical space, a POI processing unit collecting attribute information from a target terminal and identifying the POI using the collected attribute information, and a virtual object processing unit matching a virtual object associated with the URI to the identified POI; and

setting coordinates on the 3D physical space such that the POI and the virtual object are displayed in a 3D virtual space through a Web browser of the target terminal, analyzing video information of the POI and the virtual object based on the set coordinates, and providing the target terminal analyzed video information.

13. The method of providing augmented reality contents based on a Web information structure according to claim 12, wherein the virtual object includes at least one of a text, an image, a moving image, and an animation to be displayed on the target terminal together with the POI.

14. The method of providing augmented reality contents based on a Web information structure according to claim 12, wherein the POI processing unit identifies the POI by using at least one of GPS information, inertial sensor information, visual sensor information, and RFID tag information as the attribute information.

15. The method of providing augmented reality contents based on a Web information structure according to claim 12, wherein the virtual object processing unit applies at least one of rotation, scaling, and inclination to the virtual object with a location of the POI set as a reference.

16. The method of providing augmented reality contents based on a Web information structure according to claim 12,

wherein the HTML document further includes an event managing unit that manages a touch event for the virtual object,

wherein the virtual object processing unit executes a touched virtual object in response to the touch event for the virtual object, and

wherein the virtual object is a moving image or music information.

17. The method of providing augmented reality contents based on a Web information structure according to claim 12, wherein the HTML document further includes an event managing unit that manages at least one of a touch event, a tracker event, a place event, and a POI event.
