Method of and system for selecting and presenting content based on user identification
First Claim
1. A user-interface method of selecting and presenting a collection of content items in which the presentation is ordered at least in part based on inferring which user of a relatively small collection of users is using an input device, the method comprising:
- providing a set of content items;
providing a set of preference information for each user of the collection of users, each set of preference information indicating content item preferences of a corresponding user;
providing a set of user keypress biometric models, each model representing expected keypress activity for the corresponding user;
receiving incremental input entered by a user for incrementally identifying desired content items, the incremental input corresponding to a sequence of keys pressed by the user on the input device;
in response to the incremental input entered by the user, monitoring and characterizing keypress activity to biometrically characterize the user, the monitoring and characterizing keypress activity including using a linear combination of at least two statistical distributions to characterize the keypress activity;
analyzing the keypress activity to find the closest match to one of the keypress biometric models;
using the closest match to infer which user of the collection of users entered the incremental input;
selecting preference information corresponding to the inferred user;
in response to selecting the preference information and the incremental input entered by the user, selecting and presenting a collection of content items in an order that portrays as relatively more relevant those content items that more closely match the set of preferences of the inferred user.

Abstract
Methods of and systems for selecting and presenting content based on user identification are provided. A user-interface method of selecting and presenting content items in which the presentation is ordered at least in part based on inferring which user of a collection of users is using an input device includes providing a set of content items, providing a set of preference information for each user indicating content item preferences of a corresponding user, and providing a set of user keypress biometric models representing expected keypress activity for the corresponding user. User keypress activity to identify desired content items is monitored to biometrically characterize the user and analyzed to find the closest match to one of the keypress biometric models. Based on the closest match, which user of the collection of users entered the input is inferred and the corresponding preference information is used to select, order, and present content items.

1. A user-interface method of selecting and presenting a collection of content items in which the presentation is ordered at least in part based on inferring which user of a relatively small collection of users is using an input device, the method comprising:
-
providing a set of content items; providing a set of preference information for each user of the collection of users, each set of preference information indicating content item preferences of a corresponding user; providing a set of user keypress biometric models, each model representing expected keypress activity for the corresponding user; receiving incremental input entered by a user for incrementally identifying desired content items, the incremental input corresponding to a sequence of keys pressed by the user on the input device; in response to the incremental input entered by the user, monitoring and characterizing keypress activity to biometrically characterize the user, the monitoring and characterizing keypress activity including using a linear combination of at least two statistical distributions to characterize the keypress activity; analyzing the keypress activity to find the closest match to one of the keypress biometric models; using the closest match to infer which user of the collection of users entered the incremental input; selecting preference information corresponding to the inferred user; in response to selecting the preference information and the incremental input entered by the user, selecting and presenting a collection of content items in an order that portrays as relatively more relevant those content items that more closely match the set of preferences of the inferred user. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 24, 25, 31)

16. A user-interface system for selecting and presenting a collection of content items in which the presentation is ordered at least in part based on inferring which user of a relatively small collection of users is using an input device, the system comprising:
-
a catalog of a set of content items; a set of preference information for each user of the collection of users, each set of preference information indicating content item preferences of a corresponding user; a set of user keypress biometric models, each model representing expected keypress activity for the corresponding user; input logic for receiving incremental input entered by a user for incrementally identifying desired content items, the incremental input corresponding to a sequence of keys pressed by the user on the input device; monitoring logic responsive to the incremental input entered by the user for monitoring and characterizing keypress activity to biometrically characterize the user, the monitoring and characterizing keypress activity including using a linear combination of at least two statistical distributions to characterize the keypress activity; analyzing logic for analyzing the keypress activity to find the closest match to one of the keypress biometric models; inferring logic for using the closest match to infer which user of the collection of users entered the incremental input; selection logic for selecting preference information corresponding to the inferred user; search logic responsive to selecting the preference information and the incremental input entered by the user, selecting and presenting a collection of content items in an order that portrays as relatively more relevant those content items that more closely match the set of preferences of the inferred user. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 26, 27, 28, 29, 30, 32)
