Project Timeline (February 2025 - April 2025)
Our team designed an Arduino-based device to help Kimberly, an independent woman with Usher Syndrome, play the guitar without relying on visual cues or multiple apps. Our team focused on developing a real-time chord progression system using a DFPlayer Mini MP3 and speaker, allowing Kimberly to play her favourite songs. Key features include ensuring ease of use through illuminated, uniquely shaped buttons for play, pause, time, and volume control. Features also included maintaining a lightweight, compact design while eliminating battery dependence for safety. The final product is in a custom 3D printed box, enhancing accessibility and independence.

Kimberly, a resident of Hamilton, Ontario faces vision and hearing challenges due to her Usher Syndrome. Specific to her sight, she experiences difficulties with colour perception, tunnel vision, and seeing in the dark. Our design should enhance her experience interacting with her environment in a more safe and independent manner.
