Recently growth of pen-computers and personal digital assistants has made electronic ink a first-class object. One of the most important problems under this model is to search ink data at previously stored pen-strokes. In this paper we proposed and implemented a matching algorithm of write-dependant ink search for oriental characters, especially mixed Korean with Chinese characters. Our algorithm is very simple guaranteeing the performance of the matching time for the mobile computer which has limitations of hardware. Various experiments showed matching rate over 98% for only the Korean scripts and 94% for the data mixed Korean with Chinese scripts.
