ARIADNE: A Wearable Platform for Evaluating Vibrotactile Motion Guidance
Vibrotactile biofeedback can enhance motor learning, sports training, and rehabilitation, but the immature designs of existing devices limit effectiveness and adoption. The common approach of strapping devices to the body introduces variability in vibration amplitude; stretchable adhesive devices standardize skin contact but require specialized manufacturing and may suffer from hysteresis and degradation. We present ARIADNE (Adhesive Resonant Interface for Applying Directional Nudges Effectively), a portable open-source platform that delivers reliable vibrotactile feedback to any part of the body. ARIADNE was validated first by using its accelerometers to examine how mechanical actuator vibration, anatomical site, and body composition affect perceived vibration strength in 20 participants. Second, ARIADNE was paired with an optical motion-capture system to teach six participants a toe-in gait, showing potential for real-time, tailored clinical studies. By openly sharing ARIADNE's hardware, software, and dynamic model, we provide tools for delivering standardized vibrations and benchmarking feedback strategies in diverse applications.
