At the receiving end is the second small box, which contains a radio receiver and another single chip microcomputer. The data received by the radio receiver is passed on to the microcomputer where it is checked for errors. Any data corrupted during the transmission process is ignored, while valid data is converted into a stream of MIDI messages that indicate the position and acceleration of the performer’s limb.  The MIDI output of this box can then be connected to any personal computer with a MIDI interface for routing to the various media devices that are being controlled. In our performances, we typically use a Macintosh computer running a software program called Isadora® that intelligently interprets the incoming data and then sends the appropriate messages to the devices being controlled. |
