电子化钢琴键盘文本输入法的实现

为打破文字的键盘输入必须使用字母和数字等键盘的束缚，提出一种利用电子化钢琴键盘的并击特性，在钢琴键盘上实现文本输入和人机交互的基本思路，及以此为根据的钢琴键盘输入法。从MIDI信号的截获和处理，字母、单词和中文字词的表示和输入，数字和符号的输入及输入焦点的选择四个方面描述了电子化钢琴键盘文本输入法的实现方案。

Implementation of the Electronic Piano Keyboard Text Input Method

In order to break the constraint of text input relying on alphabetical and numeric keyboards, an idea of text input and human-computer interaction on the piano keyboard was implemented by using the parallel operation of e- lectronic piano keyboard, and based on witch piano keyboard text input method was achieved. The implementation scheme was illustrated from the four aspects： The capturing and processing of MIDI signal; the representation and input of letters, words and Chinese words; the numbers and symbols input and the selection of input focus.
