Abstract

The present invention relates to a tabletop, mobile augmented reality system for personalization and cooperation and an interaction method using augmented reality. More particularly, the tabletop, mobile augmented reality system for personalization and cooperation according to the present invention adds a mobile interface for providing a personal user space to a table interface for providing a cooperative space for users such that information on a table can be brought to a personal mobile device and controlled directly or manipulated personally by a user, allows for fairness in the right to control the table, and permits users to share the result of personalization. The tabletop, mobile augmented reality system for personalization and cooperation according to the present invention includes a table interface for providing a cooperative space, which allows for interaction among users by enabling users to touch a specific piece of content of the image projected onto a table or via an object disposed on the specific piece of content. The invention further relates to a mobile interface for providing a personal space, which recognizes and traces said object to augment the image projected onto the table with three-dimensional content.

Claims

1. A tabletop, mobile augmented reality system for personalization and cooperation, comprising:

a table interface providing a cooperative space for touching specific content of an image projected on a table or interacting with a user through an object disposed on the specific content; and

a mobile interface providing a personal space augmenting three-dimensional content on the projected image by recognizing and tracing the object.

2. The tabletop, mobile augmented reality system for personalization and cooperation according to claim 1, wherein the table interface includes:

an input module receiving input from a user;

a scene composing module composing a scene from data transmitted from the input module;

a viewer module displaying the scene composed by the scene composing module; and

a network module for connection with the mobile interface.

3. The tabletop, mobile augmented reality system for personalization and cooperation according to claim 2, wherein the input module is a touch frame recognizing touch of the user.

4. The tabletop, mobile augmented reality system for personalization and cooperation according to claim 2, wherein the input module is a camera recognizing the object.

5. The tabletop, mobile augmented reality system for personalization and cooperation according to claim 1, wherein the mobile interface includes:

a trace module recognizing and tracing objects;

a network module for connection with the table interface;

a registration module augmenting an image transmitted from the trace module with three-dimensional content; and

a viewer module displaying an image augmented by the registration module.

6. The tabletop, mobile augmented reality system for personalization and cooperation according to claim 5, wherein the trace module includes a camera.

7. The tabletop, mobile augmented reality system for personalization and cooperation according to claim 5, wherein the mobile interface further includes an input module for interaction with the three-dimensional content.

8. The tabletop, mobile augmented reality system for personalization and cooperation according to claim 7, wherein the input module includes a touch panel.

9. The tabletop, mobile augmented reality system for personalization and cooperation according to claim 1, wherein the object has the same coordinate values in the table interface and the mobile interface.

10. The tabletop, mobile augmented reality system for personalization and cooperation according to claim 1, wherein the table interface and the mobile interface exchange and transmit coordinate data of the object by networking, and the transmission is performed in temporal synchronization.

11. An interaction method using augmented reality, comprising:

(a) disposing an object onto a table interface;

(b) recognizing and tracing the object with a camera equipped in the mobile interface;

(c) augmenting an image acquired by the camera with three-dimensional content; and

(d) performing interaction by selecting or manipulating three-dimensional content.

12. The interaction method using augmented reality according to claim 11, further comprising manipulating the object on the table interface.
