First Claim
Patent Images
1. A method for scaling handwritten character input for performing handwriting recognition, the method comprising the computer implemented steps of:
- deriving a stroke parameter from a first handwritten character stroke;
calculating an input area in which the first handwritten character stroke was supplied; and
scaling the stroke parameter according to the input area.

Abstract
A method, computer program product, and a data processing system for scaling handwritten character input for performing handwriting recognition. A stroke parameter is derived from a handwritten character stroke and an input area is calculated in which the handwritten character stroke was supplied. The stroke parameter is scaled according to the input area.
