Abstract

An image generating system for simultaneous visual representative display of multiple computer users is disclosed. The method and apparatus includes hardware, software, and a system for generating various images for one or more users of a connected computer system, and imposing them onto the systems and ultimately the visual display of each user'"'"'s system. The images, which may be known as avatars, may be static images, animated 2D, and/or animated 3D images. The images are simultaneously displayed on the outputs of each user. Each user may react and interact with the images of the other users through their own image.

Claims

1. The image generating method for simultaneous representative visual display of multiple computer users, the image generating method comprising steps of:

visiting a web page in that a first computer user navigates a first web browser on a first computer to said web page such that said web page is shown on a web browser window of said first web browser on said first computer,

performing location mapping in that;

a first co-presence manager on said first computer performs a computation using a URL of said web page as an input and such that a co-presence channel name and an address of a co-presence server result, said first co-presence manager using said URL and no input from said web page in said computation, and

said first computer then notifies said co-presence server of said visiting of said web page by said first computer user in that said first computer transmits said co-presence channel name to said address of said co-presence server,

generating a first image package representative of said first computer user,

visiting said web page in that a second computer user navigates a second web browser on a second computer to said web page such that said web page is shown on a web browser window of said second web browser on said second computer,

performing location mapping in that;

a second co-presence manager on said second computer performs a computation using a URL of said web page as an input and such that a co-presence channel name and an address of a co-presence server result, said second co-presence manager using said URL and no input from said web page in said computation, and

said second computer then notifies said co-presence server of said visiting of said web page by said second computer user in that said second computer transmits said co-presence channel name to said address of said co-presence server,

generating a second image package representative of said second computer user,

displaying said first image package on said web browser window of said first computer over said web page, and

displaying said second image package on said web browser window of said first computer over said web page.

2. The image generating method for simultaneous representative visual display of multiple computer users according to claim 1, wherein said first and second image packages are integrated with said web browser window of said first web browser of said first computer.

3. The image generating method for simultaneous representative visual display of multiple computer users according to claim 1, further comprising the steps of assigning first coordinates to the first image package, and assigning second coordinates to the second image package.

4. The image generating method for simultaneous representative visual display of multiple computer users according to claim 3, further comprising the step of positioning said first image package and said second image package on said web browser window of said first web browser of said first computer utilizing said first and said second coordinates.

5. The image generating method according to claim 1, further comprising steps of:

establishing said first image package in the form of an avatar,

establishing avatar graphics data,

establishing avatar copresence data,

establishing a transparency mask, the transparency mask defining the shape of said first image package independent of a background,

establishing a window manager, said window manager identifying the absolute coordinates of said web browser window of said first web browser of said first computer, and

wherein said first co-presence manager identifies the required components of individual image packages which are to be drawn at coordinates relative to said web browser window, for receiving web browser window information and address information of said web page, and for communicating information about the presence of said first computer user on said web page to said co-presence server,

establishing a virtual presence service comprising a co-presence service, at least one avatar server, and at least one communication server, the co-presence service comprising said co-presence server, said co-presence server being for creating a co-presence list of users using said web page, for communicating the list to at least one co-presence client, and for acquiring for each user at least one user identifier, at least one avatar data identifier, and an avatar version identifier,

wherein the method further comprises steps of;

communicating via the at least one avatar server information describing the appearance and identity of the avatar,

communicating via the at least one communication server data between users represented as avatars,

establishing an avatar data container,

establishing at least one co-presence client for communicating information about the appearance of the avatars, for accumulating sufficient data to render an avatar on a screen position where the avatar appears associated with said web browser window, and for communicating a presence of said avatar to the copresence service, and

establishing a mapping rule service, mapping rules, regular expressions, and message digests,

wherein multiple users being represented as avatars are able to interact with awareness of each other together on a single web page.

6. The image generating method according to claim 5, further comprising the step of generating an avatar status tag for at least one avatar.

7. The image generating method according to claim 5, further comprising the step of generating text based chat and communicating the text based chat between users.

8. The image generating method according to claim 5, further comprising the step of utilizing a chat server as said co-presence server.

9. The image generating method according to claim 5, further comprising the step of establishing cached data including avatar information and establishing an invalidation strategy to analyze the cached data and reacquire new avatar data.

10. The image generating method according to claim 5, further comprising the step of transmitting sound between co-presence clients.

11. The image generating method according to claim 5, further comprising the step of generating a popularity index by measuring the number of users who access particular sites.

12. The image generating method according to claim 5, further comprising the step of adapting the avatar to a mobile device display, and employing a co-presence proxy to reduce traffic on a wireless connection.

13. The image generating method according to claim 5, further comprising the step of implementing at least one game avatar on the web page.

14. The image generating method according to claim 5, the avatar data container having at least one component, the component comprising avatar data and/or an identifier referencing another container.

15. The image generating method according to claim 5, wherein the window manager identifies the position size and visibility of the web browser window, and the position of the content of the web browser window.

16. The image generating method according to claim 5, further comprising the step of using a 3D model base to generate avatar graphics.

17. The image generating method according to claim 5, further comprising the step of exporting avatars from other game-like environments into the present system.

18. The image generating method according to claim 5, further comprising the step of utilizing virtual non-avatar objects.

19. The image generating method according to claim 5, further comprising the step of utilizing advertising graphics displayed by avatars, bots, and/or virtual objects.

20. The image generating method according to claim 5, further comprising the step of positioning avatars and/or virtual objects away from the two dimensional web page.

21. The image generating method according to claim 5, further comprising the step of facilitating the cooperation and interaction of avatars, and allowing for the interaction to alter the appearance of the respective avatars.
