1. A method for character identification on a multi-touch surface, the method comprising: presenting, by one or more computer processors, a list of a plurality of general classifiers, and, in response to a user selecting one or more general classifiers from the list of the plurality of general classifiers, storing, by one or more computer processors, the one or more general classifiers in a profile associated with the user; receiving, by one or more computer processors, data indicating a hand is on a touch-sensitive surface; identifying, by one or more computer processors, a position of the hand; determining, by one or more computer processors, a change in the position of the hand; identifying, by one or more computer processors, the one or more general classifiers from the profile; identifying, by one or more computer processors, one or more specific classifiers from a plurality of specific classifiers based, at least in part, on a training phase; modifying, by one or more computer processors, an algorithm based, at least in part, on the identified one or more general classifiers and the identified one or more specific classifiers; the modified algorithm analyzing, by one or more computer processors, the change in the position of the hand; the modified algorithm generating, by one or more computer processors, a list of characters that correspond to the analyzed change in the position of the hand, based, at least in part, on the one or more general classifiers; and to refine a characterization of the change in the position of the hand, selecting, by one or more computer processors, a character from the generated list of characters, based, at least in part, on the analyzed change in the position of the hand and the one or more specific classifiers;
