Method For Encoding Chinese And Japanese Ideographic Characters For Computer Entry, Retrieval And Processing

View page
US Patent:
57900558, Aug 4, 1998
Filed:
Sep 22, 1994
Appl. No.:
8/310726
Inventors:
Cho Jen Yu - Irvine CA
International Classification:
H03K 1794
US Classification:
341 28
Abstract:
This invention is for encoding of Chinese & Japanese ideographic characters which are digitized into a numeric format compatible for computer access and retrieval. Each Chinese & Japanese character is indexed by a numerical code. Each character is individually identified by an eight(8)-digit Geo-Stroke code, comprised of a four (4)-digit "FRAME" code and a four (4)-digit "ID" code. The coding method conforms to general writing habits, resulting in an input method both easy and convenient for an operator to learn and utilize. Each of the (10) Geostrokes used to input Chinese & Japanese character is assigned to a numeric digit (0-9). Each of the Geostrokes resembles one of the numeric digits available on the 10-key pad. By using this method both Chinese and Japanese ideographic character can be easily input and retrieved by using a 10-key design. By using this invention, both Chinese and Japanese computer users can now use one entry system to manipulate both languages and be completely compatible and interchangeable.
