Description

A speculative clip-on augmentation positioned between the bridge and fingerboard, using two moving tensioners that hold the bow and shift position according to the string being played. Rather than enforcing a fixed path, it makes bow deviation perceptible through graded friction that increases as the bow drifts, aiming to build muscle memory through repeated practice. Envisioned functions include non-visual feedback for drift and contact-point change, continuous low-attention feedback enabling mid-stroke correction, adaptive bow-lane awareness for dynamics, and practice scaffolding with post-practice summaries.

Design Implications

Context

Requirements

• Must preserve freedom of movement and function as a learning companion rather than define a single correct technique or replace instruction.

Constraints

• Speculative concept not yet evaluated in deployed contexts; the authors state whether it works in practice remains to be evaluated.

Target Learners

• Violin and viola learners with blindness and low-vision

Learning Goals

• Straight bow path, contact-point awareness, and bow-lane control for dynamics

Claims

• Blv Bow Drift Late Detection Over Gripping [+M]

Related Designs

• Augmented bow hold aid with finger pressure force mapping
• Left-hand alignment wearable with personalized baseline and event-based haptic feedback
