一种晃动智能手机产生音乐的方法

A Music Generation Method by Hand-waving with Smartphone

受物联网让物体开口说话启发,利用智能手机自带的传感器感知手机状态并生成音乐旋律,无需额外硬件设备。通过对内置于智能手机中的传感器进行尝试后,选择加速度传感器进行体感交互,在手持智能手机前想象一个基于传感器的空间坐标系,沿+x、-x、+y、++y、-y、–-y、+z和-z坐标轴挥动智能手机获得感知相关数据,根据数据将八度音符映射到不同的手部挥动动作,驱动扬声器奏出相应音符。基于Android平台开发的应用程序实验表明,根据动作与音符的映射可演奏《小星星》等简单乐曲旋律,能将智能手机变成一种乐器,适合低年龄阶段等人群基于自身交互进行音乐启蒙教育,做到寓教于乐。

Inspired by the Internet of Things allowing objects to speak,let the smartphone′s built-in sensors sense the phone′s status and gen-erate music melodies without the need for additional hardware devices.After experimenting with sensors embedded in smartphones,the main idea is to imagine a sensor based spatial coordinate system in front of a handheld smartphone,and swing the smartphone along the+x,-x,+y,++y,-y,-y,+z,and-z axes to obtain perceptual data.Based on the data,octave notes are mapped to different hand movements,driving the speaker to play the corresponding notes.Experiments on applications developed on the Android platform have shown that simple melodies such as"Little Stars"can be played based on the mapping of actions and notes,turning smartphones into musical instruments suitable for young people and other groups to engage in music enlightenment education based on their own interaction,achieving the goal of teaching through music.
