Abstract

This paper presents a database of on-line handwritten character patterns sampled in a sequence of sentences without any instructions. The sentences according to which character patterns are collected have been picked up from newspaper to include 1,227 frequently appearing character categories with the result that they are composed of about 10,000 characters and include 1,537 JIS 1st level character categories. The rest of the JIS 1st level 1808 categories have been added at the end of the above text and written one by one. The total text has been commonly employed for collecting script patterns from a number of people. Patterns offered were inspected and omissions and wrong patterns were rewritten. We collected data from 80 people and made the 12,000 x 80 patterns available since February 1996. More patterns are being collected. This paper describes the characteristics of this database as well as several tools to collect patterns.
