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 for comprising:

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

wherein the virtual object information corresponding to a predetermined avatar type comprises at least an Appearance element and a HapticPropertyList element selected from the predetermined avatar type, the predetermined avatar type comprising the Appearance element, an Animation element, a CommunicationSkills element, a Personality element, a ControlFeatures element, and the HapticPropertyList element,

wherein the HapticPropertyList elements denotes a list of haptic properties,

werein the CommunicationsSkills element denotes communication skills;

ControlFeatures denotes control features,

wherein and the ControlFeatures element denotes control features;

wherein the Appearance element comprises at least one sub-element selected from a predetermined avatar appearance type,

wherein the predetermined avatar appearance type comprises a sub-element selection list comprising a Body sub-element, a Head sub-element, an Eyes sub-element, an Ears sub-element, a Nose sub-element, a MouthLip sub-element, a Skin sub-element, a Facial sub-element, a Nail sub-element, a Hair sub-element, an EyeBrows sub-element, and a FacialHair sub-element,

wherein the MouthLip sub-element denotes a mouth and a lip;

wherein the EyeBrows sub-element denotes eyebrows;

wherein the FacialHair sub-element denotes facial hair,

wherein the sub-elements in the predetermined avatar appearance type comprises a hapticIDRef attribute denoting identification information regarding the haptic property information included in the HapticPropertyList,

wherein the HapticPropertyList element comprises a plurality of haptic properties of the avatar type,

wherein the hapticIDRef attribute in the at least one sub-element of the Appearance element refers to one of the plurality of haptic properties in the HapticPropertyList element, and

wherein the extractor is configured to;

extract the hapticIDRef attribute from a sub-element, from among the at least one sub-element of the Appearance element; and

extract a haptic property, from among the plurality of haptic properties of the HapticPropertyList element, corresponding to the extracted hapticIDRef attribute, and

wherein the apparatus is configured to identify the listed sub-elements for extracting the haptic property, and

wherein the extracted haptic property is used for providing haptic feedback.

2. The apparatus of claim 1, further comprising:

a receiver configured to receive sensed information from a sensor.

3. The apparatus of claim 2, wherein the extractor is further configured to extract the hapticIDRef attribute from the sub-element, among the at least one sub-element of the Appearance element, corresponding to the sensed information received from the sensor.

4. The apparatus of claim 2, wherein the extractor is further configured to

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

extract a sub-element corresponding to the extracted portion;

and

extract a hapticIDRef attribute from the sub-element corresponding to the extracted portion.

5. 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.

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

7. A method comprising:

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

wherein the virtual object information corresponding to a predetermined avatar type comprises at least an Appearance element and a HapticPropertyList element selected from the predetermined avatar type, the predetermined avatar type comprising the Appearance element, an Animation element, a CommunicationSkills element, a Personality element, a ControlFeatures element, and the HapticPropertyList element,

wherein the HapticPropertyList element denotes a list of haptic properties,

wherein the CommunicationsSkills elements denotes communication skills; and

wherein the ControlFeatures elements denotes control features;

wherein the Appearance element comprises at least one sub-element selected from a predetermined avatar appearance type,

wherein the predetermined avatar appearance type comprises a sub-element selection list comprising a Body sub-element, a Head sub-element, an Eyes sub-element, an Ears sub-element, a Nose sub-element, a MouthLip sub-element, a Skin sub-element, a Facial sub-element, a Nail sub-element, a Hair sub-element, an EyeBrows sub-element, and a FacialHair sub-element,

wherein the MouthLip sub-element denotes a mouth and a lip;

wherein the EyeBrows sub-element denotes eyebrows; and

wherein the FacialHair sub-element denotes facial hair,

wherein the sub-elements in the predetermined avatar appearance type comprises a hapticIDRef attribute denoting identification information regarding the haptic property information included in the HapticPropertyList,

wherein the HapticPropertyList element comprises a plurality of haptic properties of the avatar type,

wherein the hapticIDRef attribute in the at least one sub-element of the Appearance element refers to one of the plurality of haptic properties in the HapticPropertyList element, and

wherein the extracting comprises

extracting the hapticIDRef attribute, and

extracting a haptic property, from among the plurality of haptic properties of the HapticPropertyList element, corresponding to the extracted hapticIDRef attribute,

wherein the apparatus is configured to identify the listed sub-elements for extracting the haptic property, and

wherein the extracted haptic property is used for providing haptic feedback.

8. A non-transitory computer readable recording medium storing a program to cause a computer to implement the method of claim 7.

9. The method of claim 7, further comprising:

receiving sensed information from a sensor.

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

extracting the hapticIDRef attribute 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 the avatar based on the sensed information received from the sensor;
