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

generating a Hypertext Markup Language (HTML) document that includes an URI setter element configured to set a uniform resource identifier (URI) corresponding to a point of interest (POI) in a three-dimensional (3D) physical space, and a virtual object processor element configured to match a virtual object associated with the URI to the POI;

collecting attribute information from a target terminal and identifying the POI using the collected attribute information;

setting coordinates on the 3D physical space such that the POI and the virtual object are displayed in a 3D virtual space through the target terminal;

analyzing video information of the POI and the virtual object based on the set coordinates; and

providing analyzed video information to the target terminal,

wherein the URI setter element and the virtual object processor element are defined as Cascading Style Sheets (CSS) in the HTML document.

2. The method according to claim 1, wherein the virtual object comprises 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 method according to claim 1, wherein a POI processor element is configured to identify the POI by using at least one of Global Positioning System (GPS) information, inertial sensor information, visual sensor information, and Radio Frequency Identification (RFID) tag information as the attribute information.

4. The method according to claim 1, wherein the virtual object processor element is configured to apply at least one of rotation, scaling, and inclination to the virtual object with a location of the POI set as a reference.

5. The method according to claim 1,

wherein the HTML document further comprises an event managing unit configured to manage a touch event for the virtual object,

wherein the virtual object processor element is configured to execute a touched virtual object in response to the touch event for the virtual object, and

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

6. The method according to claim 1, wherein the HTML document further comprises an event manager element configured to manage at least one of a touch event, a tracker event, a place event, and a POI event.

8. The apparatus according to claim 1, wherein the virtual object comprises 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.

9. The apparatus according to claim 1, wherein the POI processor element comprises a first application code that identifies the POI by using at least one of Global Positioning System (GPS) information, inertial sensor information, visual sensor information, and Radio Frequency Identification (RFID) tag information as the attribute information.

10. The apparatus according to claim 1, wherein the virtual object processor element is configured to match the virtual object such that the virtual object is located to overlap the identified POI.

11. The apparatus according to claim 10, wherein the virtual object processor element comprises 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.

12. The apparatus according to claim 11, wherein the second application code locates the virtual object on the POI by using a style sheet representing a 3D space.

13. The apparatus according to claim 1, wherein the processor further comprises an event manager configured to manage a touch event for the virtual object,

wherein the virtual object processor element is further configured to execute a touched virtual object in response to the touch event for the virtual object.

14. The apparatus according to claim 13, wherein the virtual object comprises a moving image or music information.

15. The apparatus according to claim 1, further comprising an event manager configured to manage at least one of a touch event, a tracker event, a place event, and a POI event.

16. 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 is configured to read the HTML document by using a Web browser.

17. The apparatus according to claim 16,

wherein the target terminal comprises a camera and a display,

wherein the camera is configured to image the POI and a peripheral environment of the POI, and

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

7. An apparatus for providing augmented reality contents, the apparatus comprising:

a processor comprising;

a three-dimensional (3D) browser engine configured to render a Hypertext Markup Language (HTML) document comprising a URI setter element configured to set a uniform resource identifier (URI) corresponding to a point of interest (POI) in a 3D physical space, and a virtual object processor element configured to match a virtual object associated with the URI to the POI; and

a POI processor element configured to collect attribute information from a target terminal and to identify the POI by using the collected attribute information,

wherein the 3D browser engine is configured to set coordinates on the 3D physical space such that the POI and the virtual object are displayed in a 3D virtual space through the target terminal, analyze video information of the POI and the virtual object based on the set coordinates, and provide the analyzed video information to the target terminal,

wherein the URI setter element and the virtual object processor element are defined as Cascading Style Sheets (CSS) in HTML document.
