This demo will showcase technologically mediated interactions between a performer playing a smart musical instrument (SMIs) and audience members using Musical Haptic Wearables (MHWs). Smart Instruments are a family of musical instruments characterized by embedded computational intelligence, wireless connectivity, an embedded sound delivery system, and an onboard system for feedback to the player. They offer direct point-to-point communication between each other and other portable sensor-enabled devices connected to local networks and to the Internet. MHWs are wearable devices for audience members, which encompass haptic stimulation, gesture tracking, and wireless connectivity features. This demo will present an architecture enabling the multidirectional creative communication between a performer playing a Smart Mandolin and audience members using armband-based MHWs.
