Engineering & Innovation Lab
Tune an instrument. Without relying on a screen.
A multisensory tuner project connecting sound acquisition, signal processing and accessible feedback for musicians.
DEVELOPMENT / MULTISENSORY INTERACTION
The need
Tuning often relies on a visual indicator. HapTone explores other ways to communicate pitch differences and make the interaction usable by blind and partially sighted musicians.
Technical building blocks
- Audio acquisition through a microphone or sensor
- Frequency estimation and pitch analysis
- Multisensory feedback, including haptic and audio feedback
- Ergonomics and independent use
A documented development approach
The May 2026 publication describes signal processing and work with Polytech’ Paris-Saclay under Amine Khettat’s supervision. Availability, final specifications and conditions of use should be confirmed with Blind Systems.
