The GuitarJam

Learning guitar from a phone means craning your neck 60° downward every time you need to check a chord — which, when you're a beginner, is constantly. GuitarJam is a Bluetooth-enabled E-ink display that clips to the guitar headstock and puts chord charts directly in the player's natural line of sight. The design process involved user interviews, anthropometric analysis, and Figma prototyping, resulting in a 75% reduction in neck deviation and a companion app model that keeps the device itself simple. E-ink was chosen for battery life, outdoor visibility, and eye comfort over a backlit screen. CAD modeled in SolidWorks with a ball-and-socket joint and spring-loaded clamp sized to the 5th percentile female grip strength.
