Abstract

A system, method, and article of manufacture suitable for automatically generating recommendations of a set of entertainment options from a larger set of entertainment options based on user preferences for those options. In particular, the present invention relates to the field of automatically generating recommendations for viewing television programs based on past viewing patterns and preferences of a group of television viewers, all of whom are physically present in front of the television. The present invention creates a user group profile based on the expressed preferences of the user group or preferences implied by past viewing patterns of the user group. The recommendations may be based on the user group'"'"'s preferences and viewing patterns for viewing during certain times of day or week or certain dates.

8. The apparatus of claim 7 wherein the profile processor is further programmed to:

a. create at least one value relating to the viewing history of a user group within that user group'"'"'s profile; and

b. create a set of recommended choices for the user group profile based at least in part on each detected user group'"'"'s viewing history for interaction choices similar to or the same as the interaction choices in the detected user group'"'"'s viewing history.

9. An entertainment system, comprising:

a. at least one entertainment system component providing programming available to at least one user, the programming being received via at least one input to the entertainment system component;

b. a persistent data store having a plurality of storage locations to store user preference data for a corresponding plurality of entertainment system user groups, wherein at least one unique storage location is dedicated to store the user preference data for a unique corresponding system user group; and

c. a profile processor, operatively in communication with the at least one entertainment system component, the persistent data store, and a user group detection system, the profile processor programmed to;

i. automatically detect which user group of the plurality of entertainment system user groups are currently within a predefined viewing area;

ii. automatically create a user group profile based on the user preference data for the user group currently detected within the predefined viewing area; and

iii. dynamically adjust operating parameters for the entertainment system in response to the user group profile.

10. A method for creating a user group profile for a user group comprising a plurality of users, the method comprising:

a. automatically detecting which of a plurality of users are currently within a predetermined viewing area;

b. determining an identity of a user group consisting of the detected plurality of users;

c. for the identified user group,

i. comparing the identified user group'"'"'s identity against a first predetermined portion of user group data stored in a persistent data store; and

ii. retrieving a second predetermined portion of user group data from the persistent data store for the identified user group; and

d. generating a user group profile from each of the second predetermined portions of user data.

11. The method of claim 10 further comprising creating a set of recommended entertainment options based on the user group profile from a set of available entertainment options.

12. The method of claim 10 wherein the user group profile may be generated by an individual who has authority to generate user group profiles for user groups which are present but who have no profile.

13. The method of claim 10 further comprising:

e. accumulating a viewing history for each detected user group, the viewing history comprising positive entertainment options;

f. adjusting the user group profile using the positive entertainment options in the viewing history wherein each positive entertainment option in the user group profile reflects a sum of occurrences of that positive entertainment option in the viewing history;

g. generating negative entertainment options for each positive entertainment option in the composite user profile;

h. determining which entertainment options available in a predetermined time frame are positively rated by the user group profile; and

i. generating a score of each positive entertainment option and negative entertainment option in the user group profile.
