This workshop focuses the sensor technology for interactive music performance with some viewpoints. At first, I will introduce and demonstrate many types of sensors as interfaces between human and computer systems, not only as technically but also as artistically with multi-media works. Secondly, I will lecture to design , develop and produce sensing system easily without expert knowledge of electronics. Thirdly, I will lecture of handling sensor information to create interactive art with MAX environment. I will take many sample sensors and many sample MAX patches, so attendants can experience treating sensors, programming the algorithms and composing sample works. Finally, we will discuss the possibility of "new human interface" and the interactivity with multi-media technology.
