ABSTRACT:
A method for correcting textual material recognized on a pen-based computer in accordance with the present invention includes the step of receiving an input on a screen of the computer system. The input is then recognized, and a bounding box defining the bounds of the input is defined. A determination of the intention and placement of the recognized input is then made according to the relationship between the bounding box of the recognized input and the bounding boxes of the already existing textual objects. When a substantial overlap is found of the recognized input with an existing textual object and the number of characters of the recognized input is less than a predetermined number, the recognized input is considered as an overwrite of the existing text. If the conditions are not met, the recognized input is considered as an insertion of a new textual object, i.e., a new word. A best potential character is determined from the recognized input if the overwrite conditions are met, and the most overlapped character of the overlapped textual object is replaced by the best potential character.
