The Sonification is a costume-controler which eagers the visualization of the dancer’s motion through sounds. The project places the body as central input. Every movement of the arms’ and legs’ articulations are used to modulate the soundscape in a space. The costume is an interactive dispositive with sensors strategically placed on the wrist, elbows and knees.
The sensors were crafted using the knitting technique with textile materials. Tests using crochet, knitting and embroidering methods demonstrate that the circular-knitting one senses the body accurately. The final costume features 6 sensors connected to a backpack containing an LilyPad with 6 voltage separating circuits, batteries and a low-power digital radio (Xbee) for communication with the external computer. Also, an application written in the Java processes the signals in real time and creates sound output through a commercial music sequencer.
The advantages of using textile sensors are related to the comfortability since the flexibility of the material allows the dancer’s expression . Another positive aspect is that the textile sensors are washable and easier to dress when compared with the hard material’s ones. On the other hand, the pain poin to use textile as sensor is the difficult to connect hard and soft materials in a robust way, especially if it is hand made as the Sonification costume.
