summary

Hybrid-Brailler combines a physical back-mounted 3x3 chorded button grid with touchscreen gestures for editing and uses a custom PCB with an Arduino and Bluetooth plus nine off‑the‑shelf buttons in a 3D‑printed case. Two user studies with blind participants show entry rates match software Braille while input accuracy dramatically improves, editing is 21% faster overall, caret success is 85% versus 55% for TalkBack, and clipboard/selection drops task time from ~3.5+ to ~2 minutes.
