Abstract

In an apparatus and method for processing a virtual world, haptic information regarding a virtual object in the virtual world, the haptic information corresponding to sensed information, is extracted and transmitted to a haptic feedback device. Accordingly, interaction between a real world and the virtual world is achieved. The processing speed of the haptic information with respect to the virtual object may be increased by varying data structures according to types of the virtual object.

Claims

1. An apparatus comprising:

an extractor to extract virtual object information for processing a virtual world,

wherein the virtual object information comprises an appearance element comprising at least one sub-element and a list element comprising a plurality of haptic properties, wherein the at least one sub-element comprises identification information referring to one of the plurality of haptic properties in the list element,

wherein the extractor is configured to

extract identification information from a sub-element, from among the at least one sub-element of the appearance element; and

extract a haptic property, from among the haptic properties of the list element, corresponding to the extracted identification information,

wherein the apparatus is configured to identify the sub-element for extracting the haptic property, and wherein the extracted haptic property is used for providing haptic feedback.

4. The apparatus of claim 1, further comprising:

a receiver configured to receive sensed information from a sensor.

5. The apparatus of claim 4, wherein the extractor is further configured to

extract the identification information from the sub-element, among the at least one sub-element of the appearance element, corresponding to the sensed information received from the sensor.

6. The apparatus of claim 4, wherein the extractor is further configured to

extract a portion of an avatar based on the sensed information received from the sensor,

extract a sub-element corresponding to the extracted portion;

and

extract the identification information from the sub-element corresponding to the extracted portion.

7. The apparatus of claim 1, further comprising:

a transmitter configured to transmit control information to a haptic feedback device based on the extracted haptic property.

8. The apparatus of claim 1, wherein the sensed information comprises position information regarding a touched position on a sensor and information on a touched portion of an avatar.

2. A method comprising:

extracting virtual object information for processing a virtual world,

wherein the virtual object information comprises an appearance element comprising at least one sub-element and a list element comprising a plurality of haptic properties, wherein the at least one sub-element comprises identification information referring to one of the plurality of haptic properties in the list element,

wherein the extracting comprising;

extracting identification information from a sub-element, among the at least one sub-element of the appearance element; and

extracting a haptic property, from among the plurality of haptic properties of the list element, corresponding to the extracted identification information,

wherein the method further comprises identifying the sub-element for extracting the haptic property, and wherein the extracted haptic property is used for providing haptic feedback.

3. A non-transitory computer readable recording medium storing a program to cause a computer to implement the method of claim 2.

9. The method of claim 2, further comprising:

receiving sensed information from a sensor.

10. The method of claim 9, wherein the extracting the hapticIDRef attribute comprises:

extracting the identification information from the sub-element, among the at least one sub-element of the appearance element, corresponding to the sensed information received from the sensor.

11. The method of claim 9, wherein the extracting the hapticIDRef attribute comprises:

extracting a portion of an avatar based on the sensed information received from the sensor;

extracting a sub-element corresponding to the extracted portion; and

extracting the identification information from the sub-element corresponding to the extracted portion.

12. The method of claim 2, further comprising:

transmitting control information to a haptic feedback device based on the extracted haptic property.

13. The method of claim 2, wherein the sensed information comprises position information regarding a touched position on a sensor and information on a touched portion of an avatar.
