Abstract

A method of provisioning avatars comprises receiving at a first computer system associated with a first user, a metadata file relating to an avatar of a second user. In particular, the metadata file comprises data for use with an avatar generator process that is in execution on the first computer system. Data is extracted from the metadata file, and is provided as input data to the avatar generator process, thereby generating locally to the first computer system the avatar of the second user. The avatar of the second user so generated is displayed to the first user within a virtual environment.

,

determining the inheritable characteristic of the avatar of the second user based on the data relating to the inheritable characteristic for each of the first ancestor avatar and the second ancestor avatar and the user defined weighting factor.

9. A method according to claim 5, comprising:

providing a non-physical feature for being associated with the avatar of the second user; and

mapping the non-physical feature onto the avatar of the second user.

10. A method according to claim 9, wherein the metadata file comprises a unique identifier of the non-physical feature.

11. A method according to claim 5, wherein the avatar generator process in execution on the first computer system is an inheritance-based three-generation avatar generator process.

12. A method according to claim 11, wherein the metadata file comprises:

at least a first unique identifier of a first grandfather avatar, a second unique identifier of a first grandmother avatar, and a first weighting factor for defining a contribution from each of the first grandfather avatar and the first grandmother avatar to an inheritable characteristic of a first parent avatar;

at least a third unique identifier of a second grandfather avatar, a fourth unique identifier of a second grandmother avatar, and a second weighting factor for defining a contribution from each of the second grandfather avatar and the second grandmother avatar to the inheritable characteristic of a second parent avatar;

and a third weighting factor for defining a contribution from each of the first parent avatar and the second parent avatar to the inheritable characteristic of the avatar of the second user.

13. A method according to claim 11, comprising:

providing a non-physical feature for being associated with the avatar of the second user; and

mapping the non-physical feature onto the avatar of the second user.

14. A method according to claim 13, wherein the metadata file comprises a unique identifier of the non-physical feature.

15. A method according to claim 5, comprising providing the metadata file to the first computer system in dependence upon at least one of the first user initiating an action within the virtual environment and the first user being presented with a choice between a plurality of different actions within the virtual environment.

16. A method according to claim 5, wherein the data file comprises at least one of a physical characteristic of a plurality of physical characteristics, a non-physical feature of a plurality of non-physical features, a unique identifier of the avatar of the second user, an identifier relating to a membership of the virtual environment, a preference of the second user, a restriction established by the second user, a restriction established in dependence of the virtual environment, and an identifier related to the second user.

17. A method according to claim 5, wherein the data file has been generated by the second user with at least one of the virtual environment, an application associated with the virtual environment, in a second virtual environment, and an application associated with the second virtual environment.

18. A method according to claim 5, wherein the metadata file comprises a language identifier determining an aspect of communications between the second user and the first user.
