支持笔输入的乐谱编辑器

Musical Notation Editor with Pen Input

设计并实现了一个支持笔输入的乐谱编辑器,用户使用笔和书写板输入乐谱手势符号,利用基于网格编码的单笔划手势识别算法识别手势符号,生成与输入相应的乐谱,具有实时播放的功能。与传统交互界面的乐谱编辑器相比较,该系统的交互方式更加符合人们对乐谱的书写和认知习惯,使乐谱的输入过程变得简单、自然、高效。

This paper introduces a pen-based musical input editor that allows user to enter easily-learned musical gestures using a pen and tablet.The system applies the technique of simple-stroke gesture recognition to identify musical symbols,and assembles identified symbols to musical notation which can be played in real time or be converted into output representations such as MIDI files.It is found that the musical input editor with Pen-based User Interfaces is more nature and effective than systems with traditional User Interfaces.
