Method and system for handwriting recognition with scrolling input history and in-place editing

Abstract

A computer implemented method for a touch screen user interface for a computer system. A first touchscreen area is provided for accepting text input strokes. A second touchscreen area is provided for displaying recognized text from the text input strokes. The text input strokes are displayed in the first touchscreen area. The text input strokes are recognized and the resulting recognized text is displayed in the second touchscreen area. A portion of the recognized text is displayed in the first touchscreen area, wherein the portion of the recognized text is shown as the text input strokes are recognized. The portion of the recognized text displayed scrolls as the new text input strokes are recognized. The portion of the recognized text in the first touchscreen area can be displayed in a different format with respect to the recognized text in the second touchscreen area. The text input strokes in a first part of the first touchscreen area are graphically shown as they are being recognized by the computer system. The touchscreen user interface method can be implemented on a PID (personal information device) and can be implemented on a palmtop computer system.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional application entitled to the benefit of U.S. patent application Ser. No. 09 / 872,245, filed May 31, 2001, entitled “Method And System For Handwriting Recognition With Scrolling Input History And In-Place Editing,” and assigned to the assignee of the present application. The subject matter in the above-identified co-pending and commonly owned application is incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to a system and method by which computing devices may more easily recognize input from a user. In particular, the present invention relates to a system and method for implementing a handwriting recognition user interface for data entry with a scrolling recognition history and in-place editing.BACKGROUND ART[0003]As the components required to build a computer system have reduced in size, new categories of computer systems have emerged. One of the new categories of computer s...

AI Technical Summary

Benefits of technology

[0014]The present invention provides a solution for providing active feedback with regard to input strokes and recognized characters as text is being entered by a user. The present invention provides a solution that does not force a user to divert attention between two different touchscreen areas as text is being entered. The present invention provides a solution that implements in-place editing of recognized text.

Problems solved by technology

Since PIDs and other similar palmtop computer systems are very small, keyboards are generally not efficient input devices.

There are a number of problems with this prior art approach.

One problem is the fact that there exists no feedback in the text entry area with regard to the entered strokes and the resulting recognized character.

Another problem is the fact that there is no easy way to move the insertion point 110 to different locations within the recognized text.

There is no easy way to move the insertion point around using the touchscreen area 101.

Another problem is the fact there is no “in-place editing” of the recognized text.

In prior art personal information device 100, there is no easy way to edit previously entered text in order to, for example, correct mistakes.

These problems limit the usability of the handwriting recognition system.

Many users simply refuse to use the handwriting recognition.
