Abstract

A method of generating an avatar for a user may include receiving image data of a user from a camera, generating feature vectors for a plurality of features of a user, associating the user with a likely user group selected from a number of defined user groups based on the feature vectors, and assigning an avatar based on the associated user group.

Claims

1. A method of generating an avatar for a user, comprising:

receiving image data of a user from a camera;

generating feature vectors for a plurality of features of a user;

associating the user with a likely user group selected from a number of defined user groups based on the feature vectors; and

assigning an avatar based on the associated user group.

2. The method of claim 1, further comprising combining the feature vectors into an aggregate feature vector, wherein the associating is based on the aggregate feature vector.

3. The method of claim 1, further comprising determining, based on the feature vectors, whether the user has a prominent feature.

4. The method of claim 3, further comprising:

when it is determined that the user has at least one prominent feature, customizing the assigned avatar to include the at least one prominent feature; and

outputting the customized avatar for user interaction.

5. The method of claim 3, further comprising, when it is determined that the user does not have at least one prominent feature, outputting the assigned avatar for user interaction.

6. The method of claim 3, further comprising updating the avatar associated with the likely user group based on the at least one prominent feature of the user.

7. The method of claim 1, further comprising detecting a user approaching the camera.

8. The method of claim 1, further comprising outputting the assigned avatar for user interaction.

9. An apparatus for avatar generation, comprising:

a video interface configured to receive image data of a user; and

an avatar generation engine configured to receive the image data from the video interface, generate feature vectors for a plurality of features of a user, associate the user with a likely user group selected from a number of defined user groups based on the feature vectors, and assign an avatar based on the associated user group.

10. The apparatus of claim 9, wherein the avatar generation engine is further configured to combine the feature vectors into an aggregate feature vector, wherein the associating is based on the aggregate feature vector.

11. The apparatus of claim 9, wherein the avatar generation engine is further configured to determine, based on the feature vectors, whether the user has at least one prominent feature.

12. The apparatus of claim 11, wherein, when it is determined that the user has at least one prominent feature, the avatar generation engine is further configured to customize the assigned avatar to include the at least one prominent feature and output the customized avatar for user interaction.

13. The apparatus of claim 11, wherein, when it is determined that the user does not have at least one prominent feature, the avatar generation engine is further configured to output the assigned avatar for user interaction.

14. The apparatus of claim 11, wherein the avatar generation engine is further configured to update the avatar associated with the likely user group based on the at least one prominent feature of the user.

15. The apparatus of claim 9, wherein the avatar generation engine is further configured to output the assigned avatar for user interaction.

16. The apparatus of claim 9, wherein the apparatus cooperates with a display to form a kiosk system, the display being configured to display the assigned avatar for user interaction.

17. The apparatus of claim 16, further comprising:

a camera configured to detect an approaching user, capture image data, and send the image data to the video interface;

a computer, the computer including the avatar generation engine and being configured to animate the avatar and to control communications between the avatar and the user; and

at least one input device configured to permit the user to interact with the displayed avatar via the computer.

18. A method of incrementally training a user group classifier, comprising:

receiving image data of a user from a camera;

generating an aggregate feature vector from a plurality of feature vectors associated with a plurality of features of a user;

receiving at least one of personal information and personal preferences input by the user;

determining a target user group for the user based on the user input;

associating the aggregate feature vector with the determined target user group; and

training a user group classifier based on the association of the aggregate feature vector with the determined target user group.

19. The method of claim 18, wherein the training comprises training the user group classifier to associate similar aggregate feature vectors of additional users with the determined target user group.

20. The method of claim 19, further comprising adjusting the user group classifier based on at least one of personal information and personal preferences input by additional users.
