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;

    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.
