Assignment4 – Visual Support for Drummers


When I think of human assistance, a topic that comes to my mind relates to music or rhythm since I’m poor at singing and playing instruments. In this¬†project, I explored an approach to extract sound information from an instrument and to provide real-time visual feedback to the player so that he is always making an ideal sound.


Using the knock sensing interface from Assignment2, I built an assistive interface for drummers. A piezo sensor attached to a drum captures the strength of hit which is sent to P5JS to visualize whether or not the strength is within an appropriate range. The red line indicates the ideal strength and the gray bar is the actual hit value. The red bar continuously changes as the music progress.
