Real-Time Setting and Processing on LCD Touch Panel for Electronic Handwriting Exercising to Chinese Character

Abstract

The LCD touch panels have become the basic parts of most products as the human–machine interfaces. The LCD touch panels can become the main parts since their working areas become the bigger, and their real-time properties become the better. That is to say, we can immediately use of the LCD touch panels as the key operating parts of some system for some picture information. It has been known the handwriting touch traces on the LCD touch panel can be displayed immediately on the liquid crystal display, which has the properties like the paper. Therefore, we can use the LCD touch panels as the tool of the handwriting exercising as the paper did. So, we present and study the electronic handwriting exercising technologies (EHET) for Chinese character. The technologies presented consisted of the hardware design, the software design, and the algorithms of the function which were the key of the system designs. Its fundamental operation frames were the page structure. It became a kind of two-part architecture which included a MCU and an integrated operation parts. Its characteristics come from permitting of LCD touch panel and need of the operation task, and made the application wider. The physical prototype implemented proved the above studies mentioned were practical and effective.
