Abstract

A method and system for data entry of handwritten text into a computer program that is not designed to accept handwritten text is provided. In preferred embodiments, the computer program is designed to operate in a windowing environment. A data entry program receives handwritten data, recognizes the data, and sends the recognized data to the computer program. The computer program processes the recognized data as if it had been entered from the keyboard. According to the present invention, the data entry program overlaps the window of the computer program with an invisible window. To the user, it looks as if the computer program is accepting handwritten data directly.
