Development of speedy and high sensitive pen system for writing pressure and writer identification

This paper describes a pen input system which was developed to obtain minute writing pressure data. When the writing pressure is small, a conventional electronic pen can´t collate writing pressure data sufficiently. However the developed pen can collate sufficient data with precision. The developed pen can manipulate any high-speed signatures by means of high-speed writing pressure processing. Further in the pen input system, writing pressure data can be obtained by using only the pen, without any tablets. The writing pressure information obtained by the developed pen input system is analyzed and applied to writer identification
