Bio-Sensing and Bio-Feedback Instruments - DoubleMyo, MuseOSC and MRTI2015 -

This report is about new instruments applied by biological information sensing and biofeedback. There were three projects developed in 2015 (1) a new EMG sensor "Myo" customized to be used as double sensors, (2) a new brain sensor "Muse" customized to be used by OSC, and (3) an originally developed "MRTI (Multi Rubbing Tactile Instrument)" with ten tactile sensors. The key concept is BioFeedback which has been receiving attention about the relation with emotion and interoception in neuroscience recently. The commercialized sensors "Myo" and "Muse" are useful for regular consumers. However, we cannot use them as new interfaces for musical expression because they have a number of problems and limitations. I have analyzed them, and developed them for interactive music. The "DoubleMyo" is developed with an original tool in order to use two "Myo" at the same time, in order to inhibit the "sleep mode" for live performance on stage, and in order to communicate via OSC. The "MuseOSC" is developed with an original tool in order to communicate via OSC, in order to receive four channels of the brain-wave, and 3-D vectors of the head. I have reported about the "MRTI2015" in past conferences, so I will introduce it briefly.
