Abstract:

Internet of Musical Things (IoMusT) devices, such as wireless musical interfaces, often lack the haptic feedback inherent to acoustic instruments, which creates challenges for accurately controlling musical output and engaging in embodied interaction. This limitation is particularly pronounced in IoMusT contexts, where complex sensor fusion and networked collaboration require enhanced state awareness. We present a systematic investigation of vibrotactile feedback design for the T- Stick, a wireless musical interface that has been in use for nearly two decades. Through exploratory design workshops with three experienced T-Stick performers using the Sonic Touch Toolkit, we examined how musicians conceptualize and implement haptic feedback for gestural control. Our findings reveal three distinct haptic feedback strategies: (1) sensor state indication, (2) patch state communication, and (3) inter-musician communication. Our work offers design strategies for integrating vibrotactile feedback into other smart digital instruments, demonstrating the potential for haptically enhanced gestural controllers for networked performers, state synchronization, and pedagogical tools for technique development.
