The method may also include presenting the associated mood effect to other users of the virtual world.

Description

BACKGROUND OF THE INVENTION

The present invention relates to virtual worlds, such as simulations of the real-world or real-life, and the like, and more particularly to managing and presenting avatar mood effects in a virtual world.
Computer based simulations are becoming more ubiquitous. Simulations may be used for training purposes, for entertainment, for commerce or for other purposes. Computer simulations such as Second Life or similar simulations present a virtual world which allows users or players to be represented by characters known as avatars. Second Life is an Internet-based virtual world launched in 2003 by Linden Research, Inc. A downloadable client program called the Second Life Viewer enables users, called “Residents”, to interact with others in the virtual world through motional avatars. The virtual world basically simulates the real world or environment. The users or residents via their avatar can explore the virtual world, meet other users or residents, socialize, participate in individual and group activities, create and trade items (virtual property) and services from one another. The challenge with respect to such simulations or virtual worlds is to make them as realistic or as much like the real-world or real-life as possible. This increases the utility of such simulations as a training tool or enjoyment of the participants or users as an entertainment medium. Current virtual worlds enable only certain limited capabilities for simulating real-world interactions such as personalization of avatars based on clothing, facial features and physique. More engaging experiences, such as moods or emotions are typically not taken into account. For example, how moods are defined and affect personal features, such as dress, facial expressions or other features, and personal interactions is lacking. Second Life is a trademark of Linden Research, Inc. in the United States, other countries or both.

BRIEF SUMMARY OF THE INVENTION

In accordance with an embodiment of the present invention, a method for managing and presenting avatar moods or mood effects in a virtual world may include allowing a mood or mood effect to be associated with a user's avatar in the virtual world from a plurality of predefined moods or mood effects. The method may also include presenting the associated mood or mood effect to other users of the virtual world.
In accordance with another embodiment of the present invention, a method for managing and presenting avatar moods or mood effects in a virtual world may include profiling a set of mood or mood effect changes to portray different real-world emotions and moods by a user's avatar to other users in the virtual world. The method may also include defining a predetermined action based on each mood or mood effect change, the predetermined action to be performed by the user's avatar in the virtual world in response to the user's avatar being associated with a mood corresponding to the mood effect change. The method may further include triggering the change in the mood or mood effect in response to occurrence of a predetermined event.
In accordance with another embodiment of the present invention, a method for managing and presenting a mood of a user's avatar in a virtual world may include presenting a mood or mood effect of the user's avatar to other users in the virtual world. Presenting the mood or mood effect may include presenting a predefined script in association with the user's avatar to other users in the virtual world to indicate the mood of the user's avatar. Presenting the mood or mood effect may also include performing a predefined action by the user's avatar to indicate the mood of the user's avatar. Presenting the mood or mood effect may additionally include presenting the user's avatar with a predetermined appearance to indicate the mood of the user's avatar.
Other aspects and features of the present invention, as defined solely by the claims, will become apparent to those ordinarily skilled in the art upon review of the following non-limited detailed description of the invention in conjunction with the accompanying figures.

FIG. 1 is a flow chart of an example of a method 100 for managing and presenting mood or mood effects in a virtual world in accordance with an embodiment of the present invention. The terms mood, mood effects, emotions or similar terms may be used interchangeably herein to describe a state of mind, feeling, mood, emotion or the like of a user, a user's avatar in the virtual world or both, and to represent or convey this mood emotion, state of mind or the like to other users in the virtual world. In block 102, a graphical user interface (GUI) may be presented to define or edit a mood effect or mood effects. The mood effects GUI may be presented in response to a user selecting a feature, such as a menu, icon or other mechanism in a virtual world being presented on a display of the user's computer system. The GUI may be presented by a user selecting or clicking-on the menu, icon or other mechanism using a computer pointing device or similar device.
Referring also to FIG. 2, FIG. 2 is an example of a GUI 200 for defining or editing mood effects in a virtual world in accordance with an embodiment of the present invention. As illustrated in FIG. 2, each mood 201 or mood effect may be defined as a profile 202, such as “happy” 204 or “sad” 206. These profiles 202 may become extremely complex similar to human moods and emotions. Examples of more complex profiles may include “very happy”, “best day of my life”, “don't talk to me”, “bad” or any other moods or emotions. The profiles may define certain actions based on these moods. For example, as illustrated in FIG. 2, an action that may be associated with the happy profile 204 may be an avatar performing a wave action 208. An example of an action that may be associated with the sad profile 206 may be utterance of a grunt 210 by an avatar.
As illustrated in block 102, mood effects may be attributes standardized by a virtual world owner or operator. The standardized mood effect attributes may be shared by other avatars in the virtual world. As described herein, the standardized moods or mood effect attributes may be stored on a system or server to permit the mood effect attributes to be shared or associated with other avatars. In accordance with an embodiment of the present invention, users or participants in the virtual system may query or request the mood effect attributes of another avatar. Responses to such queries or requests may assist in automated responses and provide a better understanding of the person or avatar with which a user's avatar may be engaged in the virtual world and to facilitate interactions between users and users' avatars in the virtual world.
In block 104, a profile defining each mood or mood effect may be received by a virtual world system or stored on a user's computer system for managing and presenting mood effects. An identification or characterization of the mood effect may be associated with each profile, such as happy, sad, angry or similar moods or emotions. As previously discussed the profiles can be relatively complex and may include different human moods and emotions and may include different levels for each mood or emotion.
In block 106, any scripts, gestures, actions, or appearances of an avatar, or other attributes may be received and stored by a system to be associated with each mood effect as part of the mood effect profile to define the mood effect. The GUI presented to define each mood effect or mood effect profile in block 102 may permit a script to be entered and stored in association with each mood effect. The script may be a visual or verbal utterance or other form of communications. The GUI may also permit an action, such as a gesture or other action to be entered and stored in association with each mood effect. A particular action may be performed by a user's avatar while the mood affect corresponding with the particular action is associated with the user's avatar. The GUI may also permit an appearance of a user's avatar to be associated with each mood effect. For example, clothing worn by the user's avatar may be different depending upon a mood of the user's avatar.
In block 108, any action or actions received and stored by the virtual world system or user's computer system in association with each mood or mood effect may be configured to be triggered by occurrence of a predetermined event, such as a virtual world event or other occurrence. For example an action may be performed by a user's avatar in response to entering an event or location, leaving an event or location, entering a mood, or leaving a mood. A particular action may also be performed by the user's avatar in response to the user's avatar coming into contact with another avatar with predetermined matched or correlated rules. For example, each of the avatars may be in a particular mood, have a particular company or organization affiliation in the virtual world, same or similar virtual world experiences or other characteristics relative to one another that prompt a predefined action. The action may be triggered in response to the avatars coming within a predetermined proximity range of one another in the virtual world.
In block 110, a user may be allowed to select a mood effect from a plurality of predefined mood effects and associated with the user's avatar in the virtual world. Each of the plurality of mood effects may be defined as previously discussed. The mood effects may be defined by the user or the mood effects may be standardized by the virtual world system operator or owner. The mood effect may be selected from a menu, dropdown list using a computer pointing device or may be selected by some other mechanism known in relation to virtual world systems, simulations or other computer applications.
In accordance with another embodiment of the present invention, the mood effect may be manually set based on inputs from the user or selection of criteria by the user. The mood effect may be tagged to the avatar by a tagging mechanism or visual identifier to present the mood or mood effect of the user's avatar to users of other avatars in the virtual world. Referring also to FIG. 3, FIG. 3 is an illustration of a tagging mechanism 300 or visual identifier to present a mood effect 302 or 304 of a user's avatar 306 or 308 in the virtual world 310 in accordance with an embodiment of the present invention. As illustrated in FIG. 3, a tag such as a smiley face 312 may represent a happy mood effect 302 and a frown 314 may represent a sad mood effect 304. As previously discussed, a script, such as scripts 316 and 318 may also be used to represent the mood or mood effect, either alone or in addition to any other representations or expressions of an avatar's mood or mood effects. Each of the scripts 316 and 318 may be visually presented in a balloon or similar means, as illustrated in FIG. 3, or the script 316 or 318 may be audibly presented and actually spoken by the corresponding avatar via speakers of a computer system, or the scripts 316 and 318 may be both visually and audibly presented. The avatar's mood may be presented to the other user in response to the avatars coming within a predetermined proximity range of one another within the virtual world.
Referring back to FIG. 1, in block 112, in accordance with an embodiment of the present invention, an indication of the mood or mood effect may be presented to other users in the virtual world in response to a predetermined virtual world event, the user's avatar entering a predetermined location, or other stimuli. A user may be requested to indicate or select a mood or mood effect for the user's avatar when logging into the virtual world. Other users may also submit queries to determine a mood of other avatars and/or to obtain more detailed information about the other avatar's mood and possible reasons for the other avatar's mood. The information may be presented to the user in response to the query. This may provide better understanding of the person or avatar with whom the user is engaging in the virtual world.
In block 114, a mood effect associated with the user's avatar may be changed in response to an input of some criteria corresponding the mood effect or selection of a different mood effect similar to that previously described. A change in the mood effect may also be triggered by an occurrence, an event, an entry into a location in the virtual world by the user's avatar or other stimuli similar to that previously discussed. An example of a method and system for automated avatar moods in a virtual world is described in U.S. patent application Ser. No. ______ (IBM Docket No. RSW920070211US1), entitled “Automated Avatar Moods in a Virtual World”, by Steven K. Speicher et al., which is assigned to the same assignee as the present invention and is incorporated herein by reference.
In block 116, changes in mood effects may be mined or recorded and tracked along with any actions taken by avatars in response to a mood effect or change in mood effect. This data may be analyzed by the virtual world owner or operator or other entities providing services in the virtual world for market data intelligence or for other purposes.
FIG. 4 is an example of a diagram of a system 400 for defining, managing and presenting mood effects in a virtual world in accordance with an embodiment of the present invention. The method 100 may be embodied in and performed by the system 400. The system 400 may include a define mood component 402 or module to allow a user or someone else, such as a virtual world operator and/or owner, to define a mood or plurality of moods or mood effects that may be associated or tagged to the user's avatar 404 in the virtual world 406. Similar to that previously discussed, standardized mood or mood effects may be defined by a virtual world owner or operator that may be shared and tagged to avatars of other users in the virtual world.
The moods or mood effects can be defined as simple profiles, such as a “Happy Avatar” 408 and a “Sad Avatar” 410, either of which may be associated with, or tagged to the user's avatar 404 to identify the avatar's mood, visually, audibly or both, to other users in the virtual world 406. The avatar mood or mood effect may be tagged to the avatar 404 using a tagging mechanism, visual identifier or other mechanism. The tagging mechanism or visual identifier may be any such mechanism used in virtual worlds or simulations to associate information or attributes to an avatar and to present such information to other users or participants in the virtual world.
The system 400 may also include a change mood component 412 or module to cause changes in moods or mood effects associated with or tagged to an avatar. As previously discussed, the change in moods may be in response to some event or condition or actions by the avatar's user, such as selecting a different mood or mood effect from a plurality of moods.
The system 400 may also include subsystems for defining the mood and changes in the mood or mood effects. For example, the system 400 may include a scripts subsystem 414, a gesture or action subsystem 416, and an appearance subsystem 418. The scripts subsystem 414 may permit a script to be entered and associated with a mood or mood effect in defining the mood or mood effect. The scripts subsystem 414 may also control presentation of the script in association with an avatar tagged with the mood corresponding to the script. The script may be words, sounds, such as grunts, groans, laugh or other utterances which may be spoken or expressed by an avatar that has been tagged with the particular mood or mood effect. The script may be presented in visual or audible form. For example, the script may be presented in a balloon, similar to balloons 316 and 318 illustrated in FIG. 3 or the script may actual be spoken by the avatar and presented through speakers of a user's computer system.
The gestures or actions subsystem 414 may permit a specific gesture or action to be entered and associated with a mood or mood effect in defining the mood or mood effect. The gestures subsystem 416 may also control performance of the gesture or action by an avatar tagged with the mood corresponding to the gesture or action. Examples of avatar actions or gestures that may be associated with a mood or mood effect may include the avatar's head being down and/or shoulders slumped forward to indicate a sad mood, clenched fists to indicate an angry mood, arms held overhead to indicate a happy mood, the avatar jumping up and down to express a happy mood, other movements of the arms, legs or other body parts or body language that may connote a particular mood or emotion or any other actions or gestures that may express a particular type of mood or emotion.
The appearance subsystem 418 may permit a specific appearance of an avatar to be entered and associated with a mood or mood effect in defining the mood or mood effect. The appearance subsystem 418 may also control the appearance of an avatar tagged with the particular mood corresponding to the appearance. Examples of avatar appearances that may express a mood or emotion may include avatar facial expressions, bright colored clothing to express a happy mood, dark, black or gray colored clothing in association with a sad mood or any other visual effects associated with appearance of an avatar in the virtual world that may suggest a mood of the avatar or user associated with the avatar.
FIG. 5 is a block schematic diagram of another example of a system 500 for managing and presenting mood effects in a virtual world in accordance with an embodiment of the present invention. The method 100 of FIG. 1 may be embodied in or performed by the system 500. The system 500 may include a module 502 for managing and presenting moods or mood effects. The module 502 may be stored on a file system 504 of an exemplary computer system 506. The exemplary computer system 506 may be used by a user, such as user 508, to access or enter a virtual world as described herein. A plurality of users 508 may each use a computer system, similar to the exemplary computer system 506, to participate in the virtual world by controlling an avatar in the virtual world associated with the user 508.
The module 502 of managing and presenting avatar mood effects in the virtual world may include a define mood sub-module or component 510. The define mood component 510 may be similar to the define mood component 402 described with reference to FIG. 4. The define mood component 510 may generate and present a GUI to the user 508 to permit a plurality of mood or mood effects to be defined by the user and associated with the user's avatar. The GUI may include provisions for entering or defining scripts, gestures, avatar appearance or similar attributes that may connote the mood of a user's avatar to other users in the virtual world. As previously described, the mood of a user's avatar may be presented to another user's avatar in response to the avatars coming within a predetermined proximity range of one another. In accordance with another embodiment of the present invention, the mood of a user's avatar may be presented to another user in response to the other user querying the mood of the user's avatar in the virtual world. The querying operation may be performed by activating or selecting the feature in a menu or other means commonly known for selecting features in virtual worlds or computing technology.
In accordance with another embodiment of the present invention, as previously described, moods or mood effects may be standardized by the virtual world owner and/or operator. Accordingly, the virtual world owner/operator may define the different mood or mood effects. The different predefined mood or mood effects may then be shared by all of the users of the virtual world and may be associated with or tagged to respective users' avatars to express or present the avatar's mood to other users in the virtual world.
The module for managing and presenting avatar mood effects in a virtual world may also include a mood inventory 512. The mood inventory 512 may store all of the moods and associated mood effects or attributes, such as scripts, gestures or actions, appearances or other attributes associated with each mood for application to the user's avatar. As previously discussed, the moods and associated mood effects or attributes may be defined by the user or the virtual world owner and/or operator may defined standardized moods and associated mood effects or attributes which may be shared among all avatars in the virtual world.
The module for managing and presenting avatar mood effects in a virtual world may also include a component 514 to control mood changes in response to predetermined stimuli. For example, mood changes may occur in response to selection of another mood by the user of the avatar, certain events in the virtual world or real world, entering or leaving a location in the virtual world, interaction with another avatar or any other stimuli that may elicit a mood change. Predetermined rules may be created or defined to evoke specific mood changes. As previously discussed, an example of a system and method for automated changes in avatar moods in a virtual world is described in U.S. patent application Ser. No. ______ (IBM Docket No. RSW920070211US1).
The computer system 506 may also include a processor 516. The module for managing and presenting avatar mood effects 502 may be accessed from the file system 504 and run on the processor 516.
The computer system may also include a display 518, a speaker system 520, and one or more input devices, output devices or combination input/output devices, collectively I/O devices 522. The I/O devices 522 may include a keyboard, pointing device, such as a mouse, disk drives and any other devices to permit a user to interface with and control operation of the computer system and to access and participate in the virtual world through the user's avatar. The display 518 may present the user's avatar and other users' avatars in the virtual world and present the features described herein for defining and managing moods or mood effects. The speaker 520 may present any sounds associated with the virtual world, such as audible mood effects or other sounds.
The system 500 may also include a server 524. A virtual world system 526 may reside and operate on the server 524. Users 508 via browsers (not shown in FIG. 5) on their computer systems 506 may access the virtual world system 526 via a network 528.
