Description

A lightweight narrow band (approximately 1.5 cm wide) worn around the lower forearm near the wrist, intended to sense wrist alignment and forearm rotation using wearable sensing modalities such as orientation and surface movement. It learns an individualized baseline rather than enforcing a universal correct posture, and provides brief, localized haptic feedback when sustained deviation such as wrist collapse or insufficient arm rotation is detected. Envisioned functions include intonation-related technique support and selective use during warm-ups or drills, removed during musical interpretation to avoid over-reliance.

Design Implications

Context

Requirements

  • Form factor must be lightweight and non-obstructive, preserving left-hand mobility for bow hold, shifting, and vibrato.

Constraints

  • The authors state that reliably inferring wrist collapse and rotation from a narrow wristband remains an open sensing question rather than a solved one.

Target Learners

  • Violin and viola learners with blindness and low-vision

Learning Goals

  • Wrist–forearm alignment, arm rotation across string crossings, and indirectly, intonation
