Abstract: A dictionary based post-processing technique for an on-line handwriting recognition system is described. An input word has all punctuation removed, and the word is checked against a word processing dictionary. If any word matches against the dictionary, it is verified as a valid word. If it does not verify, a stroke match function and a spell-aid dictionary are used to construct a list of possible words. In some cases, the list is appended with possible words based on changing the first character of the originally recognized word. A character-match score, a substitution score and a word length are assigned to the items on the list. A word hypothesis is constructed from the list with each such word being assigned a score. The word with the best score is chosen as the output word for the processor.

Abstract: In an on-line handwriting recognition system, case confusion is resolved by a majority voting rule. A postprocessing case model makes alphabetic/numeric and upper case/lower case decisions relative to each character in a given word. A word received by a postprocessor counts the non-case-confusable members for each character in a given class. According to the majority of non-case-confusable occurrences for each class, a decision is made whether most of the characters in the word are numeric digits or alphabetic letters, and if letters whether mostly upper case or lower case. The word is then processed again to determine if it should be converted to a similar prototype from a majority case group or whether it should be left unchanged based on the majority of nonconfusable case occurrences.

Abstract: A server system (195) is connected to a plurality of kiosks (100) by a network (150), e.g., the Internet, corporate or government intranets, extranets, etc. A kiosk has one or more predetermined input/output devices (130) (e.g. displays, keyboards, paper printers, telephones, etc.) and one or more driver programs (440) (local APIs) for each of the input/output devices. The displays are used to present one or more graphical user interfaces (105) and video images to a user of the kiosk. The kiosk has a browser (160) which it uses to obtain material from the server. The server has one or more application files (175) or configuration sets that it serves to the kiosks. The configuration sets are application specific (an application is a use for which the kiosks are configured or reconfigured). One or more of the files in the configuration sets include one or more embedded control programs (620) that are used to control the local APIs for the devices on the kiosk. In this way, the devices are controlled to configure the kiosk to perform the application.

Abstract: For use in a handwriting recognition system a method, and apparatus for accomplishing same, that includes the steps of (a) inputting a plurality of strokes each of which is a constituent stroke of a symbol or symbols to be recognized by the system; (b) forming from the inputted strokes a first set (CHR) comprised of one or more symbols; and (c) averaging at least one characteristic of similarly formed symbols that are members of the first set to form a second set (AVG) comprised of prototype symbols to which, during the use of the system, assemblages of input strokes are compared. The method further includes the steps of (d) identifying a symbol or symbols of the second set that corresponds to only a single symbol of the first set; and (e) deleting the identified symbol or symbols from the second set. The method further includes the steps of (f) decomposing into constituent strokes the prototype symbols of the second set; and (g) forming a third set (STK) comprised of the constituent strokes of the second set to which, during the use of the system, input strokes are compared.

Abstract: Method and apparatus for identifying a valid symbol or a string of valid symbols from a sequence of handwritten strokes. A method includes the steps of (a) generating in response to one or more handwritten strokes a plurality of stroke labels each having an associated score; (b) processing the plurality of stroke labels in accordance with a beam search-like technique to identify those stroke labels indicative of a valid symbol or portion of a valid symbol; and (c) associating together identified stroke labels to determine an identity of a valid symbol or a string of valid symbols therefrom. An aspect of the invention is that each of the constraint validation filters is switchably coupled into a serial filter chain. The switches function to either couple a filter input to a stroke label or decouple the input and provide a path around the filter block. An application writer has available a plurality of constraint filters. The application writer specifies which one or ones of the constraint filters are to be applied for a specific sequence of strokes.
