Modifying avatar behavior based on user action or mood

1. A computer-implemented method for modifying an avatar associated with an identity, the method comprising:

inferring, by one or more processors, a mood of an online user based on information other than an explicit user indication of the mood and other than instant messaging communications, the mood including an emotional state, wherein inferring the mood of the online user includes:

determining, from the user's computer, other applications that are active near the time that an instant message is sent, and

inferring a mood of an online identity based on the determined other applications; and

modifying, by the one or more processors, an avatar associated with the online user in response to the inferred mood, the modification causing the avatar to exhibit the inferred mood, and the modifying including:

accessing information that maps a single trigger used to animate the avatar to multiple different avatar animations, the single trigger including a character string, and each of the multiple avatar animations being associated with a different mood such that the single trigger causes a different animation to be played for each mood exhibited by the avatar, and

modifying, based on the accessed information, the avatar in response to the inferred mood of the user such that identification, by a processor, of the trigger in an instant message causes a different animation to be played by the modified avatar than the animation caused to be played by the unmodified avatar in response to the trigger.

2. The method of claim 1 wherein inferring a mood of an online identity further includes inferring the mood based on evaluated user behavior.

3. The method of claim 2 wherein the evaluated user behavior includes one of a duration of online presence, intensity of online activity, and type of online activity.

16. The method of claim 13 wherein the device is a heart rate monitor worn by the user.

17. The method of claim 1 wherein inferring a mood of an online identity comprises:

determining, from the user's computer, other applications that are active at the time that an instant message is sent; and

inferring a mood of an online identity based on the determined other applications.

18. The method of claim 1 wherein inferring a mood of an online identity further includes inferring the mood based on one or more out-of-band communications indicators.

19. A non-transitory computer-usable medium having a computer program embodied thereon, the computer program comprising instructions for causing a computer to perform the following operations:

infer a mood of an online user based on information other than an explicit user indication of the mood and other than instant messaging communications, the mood including an emotional state, wherein the instructions for causing the computer to infer the mood of the online user include instructions for causing the computer to:

determine, from the user's computer, other applications that are active near the time that an instant message is sent, and

infer a mood of an online identity based on the determined other applications; and

modify an avatar associated with the online user in response to the inferred mood, the modification causing the avatar to exhibit the inferred mood, wherein the instructions for causing the computer to modify an avatar associated with the online user in response to the inferred mood include instructions for causing the computer to:

access information that maps a single trigger used to animate the avatar to multiple different avatar animations, the single trigger including a character string, and each of the multiple avatar animations being associated with a different mood such that the single trigger causes a different animation to be played for each mood exhibited by the avatar, and

modify, based on the accessed information, the avatar in response to the inferred mood of the user such that identification, by a processor, of the trigger in an instant message causes a different animation to be played by the modified avatar than the animation caused to be played by the unmodified avatar in response to the trigger.

20. The medium of claim 19 wherein the instructions for causing the computer to modify an avatar include instructions for causing the computer to modify appearance of the avatar in response to the inferred mood.

21.
