Abstract

In described embodiments, fluid user models are employed for personalized mobile applications, referred to herein as recommender systems. The described embodiments augment media with additional information highly personalized to a user based on a variety of factors with different time sensitivity and include, but are not limited to, a user'"'"'s general preferences, history, immediate context and attention, and emotional states when the user experiences and/or interacts with the media. Embodiments solve various problems of information overload stemming from both i) the complexity in characterizing the information and ii) its potential relevancy and in understanding and coding the user'"'"'s needs.

Claims

1. A method, comprising the steps of:

playing a media presentation to a user,

capturing user data and media data, while the media presentation is played;

providing tagged annotations of the media to the user,

simultaneously computing a state of the user and a state of the media based on the user data, the media data and the tagged annotations by inferring and reasoning engines, wherein the state of the user is computed based on a fluid user model providing a fluid user profile in which user'"'"'s interests are shifted over time as the user receives the media presentation;

inferring preliminary annotations based on the computed state of the user, the computed state of the media, the tagged annotations, and interaction by the inferring and reasoning engines;

generating relatively optimized plausible annotations from the preliminary annotations for a given time interval by an optimization engine; and

updating the tagged annotations of the media with the optimized plausible annotations for the user,

repeating the steps of the computing, the inferring, the generating, and the updating as the user receives the media presentation.

2. The method of claim 1 further comprising a step of collecting at least one of express interests and moods by the user before the step of the playing the media presentation.

3. The method of claim 1 further comprising a step of storing the updated tagged annotations in a memory or a server as part of the media for later use.

4. The method of claim 1, further comprising a step of sharing the updated tagged annotations with the user'"'"'s social network.

5. The method of claim 1, further comprising a step of displaying the updated tagged annotations on a display device.

6. The method of claim 7 wherein the display device is a device for a mobile application including at least one of a smart TV, a laptop, a tablet, and a smart phone.

7. The method of claim 1 further comprising a step of capturing a user'"'"'s feedback either explicit through an interface or implicit by user'"'"'s viewing behavior.

8. The method of claim 1 wherein the inferring and reasoning engines are processors executing corresponding inferring and reasoning algorithms.

9. The method of claim 1 wherein the optimization engine is a processor optimizing based on a predetermined optimization algorithm.

10. The method of claim 1 wherein the step of the computing the state of the user includes a step matching the state of the user to an immediate state of the user by a matcher;

11. The method of claim 10 wherein the matcher is a processor.

12. The method of claim 1 wherein the step of the inferring the preliminary annotations includes a step of matching the inferred preliminary annotations an immediate state of the user by a matcher.

13. The method of claim 1 wherein the step of the optimizing the plausible annotations includes a step of matching the plausible annotations selected from the preliminary annotations to an immediate state of the user by a matcher;

14. The method of claim 1 wherein the fluid user model includes a collection of interests of the user from the user data collected at a time when the user is viewing the media presentation, wherein the user'"'"'s interests are at least one of a relatively static interest and a time dependent interest.

15. The method of claim 14 wherein the user'"'"'s time dependent interests are inferred in real time using knowledge about user'"'"'s general disposition, taste, past behavior, immediate environment and recent history.

16. The method of claim 1 wherein the fluid user model includes a list of inference rules employed to compute and monitor a user'"'"'s attention and a user'"'"'s current attention level based on a variety of time dependent parameters including at least one of the user'"'"'s activities, mood, emotion, level of attention and recent history.

17. The method of claim 16 wherein the inference rules specify the conditions to select annotations for display to the user.

18. The method of claim 1 wherein the step of the computing the state of the user is based on the user data and the tagged annotations of the media.

19. The method of claim 18 wherein the step of the computing the state of the user includes a step of matching the user'"'"'s state to a user'"'"'s immediate state.

20. The method of claim 1 wherein the step of the computing the state of the media is based on the media data.

21. The method of claim 1 wherein the user data includes static data and non-static data of the user.

22. The method of claim 21 wherein the user'"'"'s static data includes at least one of interests and context.

23. The method of claim 21 wherein the user'"'"'s non-static data includes one or more of current context, current mood, current energy level, current activities, recent history, longer term history, future plans, behavior, interactions with the system, transient or opportunistic interests, and user'"'"'s attention level as a result of current activities.

24. The method of claim 1 wherein the media data includes media static data and media non-static data.

25. The method of claim 24 wherein the media static data includes media metadata capturing one or more facts comprising genre, elements of the media presentation, database facts, and a map of the media such as a table of contents or scene descriptions.

26. The method of claim 24 wherein the media non-static data includes a current sound track for the media and visual snippets of the media.

27. The method of claim 24 wherein the media non-static data is sensor data.

28. The method of claim 1 wherein the media is a mobile application of at least one of a smart TV, PC, laptop, tablet, smart phones and personal digital assistant.

29. The method of claim 1 wherein the updated tagged annotations include texts, images, graphics, video, and audio.

30. The method of claim 1 wherein the state of the user includes one or more of interests, preferences, context, mood, attention level, and transient parameters of the user.

31. The method of claim 1 wherein the state of the media includes attributes that help pinpoint parts of the time dependent media including scenes, music score, clock time, screenplay, music score, shooting locations, casting, and production of the media.

32. The method of claim 1 wherein the updated tagged annotations for the user are displayed in a fashion including one or more of a viewing screen of the media, on a secondary screen and stored in a file for viewing by the user at a later time.

33. The method of claim 1 wherein the fluid user model is an immersive model.

34. A computer system for media annotations comprising:

a memory for storing static and non-static media data and static and non-static user data;

at least one processor attached to the memory wherein the at least one processor is configured to;

collect static user data and static media metadata, while a media presentation is played on a media to a user;

capture non-static user data and non-static media data;

provide tagged annotations;

simultaneously compute a state of the user and a state of the media in real time;

generate preliminary annotations based on the computed state of the user, the computed state of the media, and the tagged annotations;

match plausible annotations selected from the preliminary annotations to an immediate state of the user;

optimize the plausible annotations for a given time interval;

update the tagged annotations with the optimized plausible annotations for next media presentation for the user; and

display the updated tagged annotations on a display device,

wherein the state of the user is computed based on a fluid user model that generates a fluid user profile, in which user'"'"'s interests are shifted over time as the user goes through the media.
