Building a Raspberry Pi-based accessible Smart Guitar
The device, which is based around a Raspberry Pi, is called the Chord Assist, created by Joe Birch, an Android Engineer and Google Developer Expert for Android.
Birch has described it as a means to help mute, deaf and blind people experience the guitar specifically, to help them learn to play chords.
The Chord Assist smart guitar allows people who are blind, deaf or mute to be able to learn, play and tune their guitar. Basically, a way to reduce the friction of learning a new instrument.
