Abstract

Avatars representing participants in a graphic chat session are periodically animated to produce a gesture that conveys an emotion, action, or personality trait. Each participant in the chat session is enabled to select one of a plurality of different avatars to represent the participant in a graphic chat session. Associated with each avatar is a bitmap file that includes a plurality of frames illustrating the avatar in different poses, actions, and emotional states. Selected frames are displayed in rapid sequence in accord with a script file to create an animation effecting each gesture. The same script file is used to define a gesture for all of the avatars used in the chat session. A selected gesture can be transmitted with a text message to convey the user'"'"'s emotional state. A gesture associated with the avatar is automatically displayed from time to time when the avatar is not otherwise gesturing or moving. The user can determine participants in the chat session with whom the user will interact, e.g., by defining a proximity radius around the user'"'"'s avatar or by selecting the specific participants from a list. Avatars of participants that are outside the proximity radius (or otherwise not selected) and messages received from them are not displayed on the user'"'"'s monitor.

Claims

1. A method for communicating a gesture by an avatar that represents a participant in an on-line graphic chat session, comprising the steps of:

(a) providing an animation in which the avatar appears to move in a defined manner that conveys the gesture, said gesture being determined by the participant to convey at least one of a pluarily of different personality traits and/or current emotions;

(b) during an idle period for the participant in the chat session, when the avatar is otherwise inactive, automatically initiating the animation without requiring any input by the participant; and

(c) during an active period for the participant in the chat session, when the avatar is performing a selected action, automatically initiating another animation in which the avatar appears to move in a defined manner that conveys another gesture, the other gesture being determined by the participant to convey at least one of a plurality of different personality traits and/or current emotions.

2. The method of claim 1, further comprising the steps of providing the participant with a plurality of avatars;

and enabling the participant to select the avatar that will represent the participant in the on-line chat session.

3. The method of claim 1, wherein the animation comprises gestures that are indicative of a personality trait and/or an emotion.

4. The method of claim 1, further comprising the step of enabling the participant to select and initiate an animation employing the avatar, said animation conveying a desired emotion and/or state of mind to another participant in the chat session.

5. The method of claim 4, wherein the animation selected by the participant to convey the desired emotion and/or state of mind is displayed simultaneously in combination with a textual message that is transmitted by the participant.

6. A method for enabling a plurality of different gestures to be implemented by a plurality of different avatars that represent participants in an on-line graphic chat session, comprising the steps of:

(a) providing a different script for each of the gestures, each script being applicable to all of the plurality of avatars used in the chat session, each gesture comprising a sequence of visual frames, said visual frames portraying different views of an avatar to produce a visual impression of an animation of said avatar when rapidly displayed in the sequence;

(b) in the script for each gesture, indicating specific visual frames comprising the sequence and time intervals determining a duration for displaying each visual frame of the sequence; and

(c) causing the avatars representing participants in the chat session to automatically implement desired gestures by selectively executing the scripts for the desired gestures, any change to a script to modify a desired gesture causing a corresponding change in said gesture for all of the different avatars executing said gesture.

7. The method of claim 6, wherein each of the plurality of avatars has at least one gesture associated with it that is automatically initiated from time to time when the avatar is otherwise inactive during the on-line chat session.

8. The method of claim 7, further comprising the step of enabling the participants in the chat session to select the gesture that is automatically initiated, each of said plurality of gestures indicating a different personality trait and/or emotion.

9. The method of claim 6, further comprising the step of enabling a participant to select a personality trait and/or emotion that will be indicated by one of the gestures to determine the gesture that will be implemented by the avatar representing the participant.

10. The method of claim 6, further comprising the step of enabling a participant to perceive communications from another participant in the chat session only if the other participant is represented by an avatar that is disposed within a defined distance of the participant'"'"'s avatar.

11. The method of claim 6, further comprising the step of enabling the participant to visually perceive a gesture implemented by the avatar that represents the participant in the chat session.

12. A system for use in enabling a participant in an on-line chat session who is represented by an avatar to indicate at least one of a plurality of different personality traits and/or current emotions to others in the on-line chat session, comprising:

(c) a memory for storing machine instructions; and

(d) a central processor for executing the machine instructions, said machine instructions, when executed by the central processor, causing the central processor to control the interface and the display, so that;

(i) an animation is provided for the avatar in the virtual space, said animation comprising a plurality of frames played in sequence so that the avatar appears to move in a defined manner within said virtual space, said movement by the avatar representing a gesture when viewed by others participating in the on-line chat session that conveys at least one of the plurality of different personality traits and/or current emotions;

(ii) during an idle period for the participant in the chat session, when the avatar representing said participant is otherwise inactive, the animation is automatically initiated; and

(iii) during an active period for the participant in the chat session, when the avatar representing the participant is performing a selected action, automatically initiating another animation in which the avatar appears to move in a defined manner that conveys another gesture, the other gesture being determined by the participant to convey at least one of a plurality of different personality traits and/or current emotions.

13. The system of claim 12, wherein the machine instructions executed by the central processor further provide the participant with a plurality of avatars;

15. The system of claim 12, wherein the machine instructions executed by the central processor further enable the participant to selectively initiate an animation that conveys a desired emotion and/or state of mind of the participant to another participant in the chat session.

16. The system of claim 15, wherein the animation selected by the participant to convey the desired emotion and/or state of mind of the participant is simultaneously activated in combination with a textual message that is transmitted by the participant.

17. A system for enabling a plurality of different gestures to be implemented by a plurality of different avatars that represent participants in an on-line graphic chat session, comprising:
