19. The system of claim 1 , wherein at least one of the locations with known coordinates in the auto-correcting region corresponds to a plurality of characters of a character set, one or a plurality of which comprise at least one diacritic mark, wherein the plurality of character set members comprise variant forms of another character set member and wherein objects in memory contain said variant forms.
1. A text entry system comprising: a user input device comprising: an auto-correcting keyboard region comprising a plurality of the characters of a character set, wherein locations having known coordinates in the auto-correcting keyboard region are associated with one or more of the character set members, wherein a location is determined when a user interacts with the user input device within the auto-correcting keyboard region and the determined interaction location is added to a current input sequence; and a memory containing a plurality of objects, wherein one or more objects comprise a string of one or a plurality of characters forming all or part of a word or phrase; an output device; and a processor coupled to the user input device, memory, and output device, said processor comprising: a distance value calculation component which, for a determined interaction location in said current input sequence, calculates a set of distance values between the interaction location and the known coordinate locations corresponding to one or a plurality of characters within the auto-correcting region; an object evaluation component which, for said current input sequence, identifies one or a plurality of candidate objects in memory, and for one or more identified candidate objects, evaluates identified candidate objects by calculating a matching metric for each candidate object by summing the distance values calculated from each interaction location in the input sequence to the location assigned to the character in the corresponding position of the candidate object and applying a weighting function, wherein the weighting function comprises multiplying the sum of the distance values by the base 2 logarithm of the ordinal ranking of the object, and, if more than one candidate object is identified, ranks the evaluated candidate objects based on the calculated matching metric values; and a selection component for identifying candidate objects according to their evaluated ranking, presenting any identified objects to the user, and enabling the user to select from among any presented objects for output to the output device.
