This paper describes two subjects regarding the on-line recognition of hand writing characters. Firstly, the necessary bandwidth to transmit a hand writing process is studied. It concludes that a band writing process can be transmitted through 320 bits/sec of less, and it means that seven or eight input terminals of hand writing can be transmitted simultaneouly with a telephone line of 2400 Baud. Secondly, an algorithm of the on-line recognition of hand writing Japanese KATAKANA characters is developed mainly based on the extraction of numbers,types and certain characteristics of strokes. Informations on time sequence and relative position among strokes are considered if necessary. The recognition experiments indicate 95% correct recognition is achieved without any preinstruction of restriction on the way of writing, and a further improvement of result, almost 100%, is possible with several instructions which do not force any essential restrictions on the way of free hand writing. A recognition time is estimated less than 50 m sec a character with a mini-computer HITAC-10
