Feel the Dots. Learn the World.
An AI-powered Braille teacher that never sleeps.
BrailleBox™ is a smart, AI-powered, low-cost Braille learning device that lets visually impaired children learn independently — through voice conversation and real tactile dots that physically rise and fall under their fingertips. No screens. No teacher required. Just feel and learn.
Talk to BrailleBox™ like a friend. ElevenLabs neural voice answers back instantly.
24 real solenoid actuators raise and lower under your fingertips — true tactile learning.
Works anywhere — Vosk + Qwen2 run fully offline with no internet required.
One large master cell teaches the current letter. Three standard cells spell entire words.
Child speaks to BrailleBox™
ElevenLabs AI or Vosk processes speech offline
Raspberry Pi fires GPIO → relay clicks → solenoid energises
Dots rise on the Master Cell — child feels the pattern
Audio confirms the letter — progress saved to profile
Watch BrailleBox™ teach the letter A — dot 1 rises in real time via 12V solenoid
ElevenLabs Conversational Agent online + Qwen2-0.5B offline fallback via Ollama.
1 Large Commercial Cell + 3 Custom Hand-wound Word Cells — pure mechanical Braille.
50MB neural model runs fully on-device. Works without internet.
Learn Mode, Assess Mode, Command Mode — Alphabet → Numbers → Word Games → Puzzles.
JSON profile per child. Stars, quiz scores, and adaptive pacing for fast or slow learners.
12V 3A PSU + 2500mAh Li-ion with PD protocol — fully portable or plug-in.
Internals — RPi + PCB + speaker + relays
3 Braille word cells — 3D printed, 6 holes each
Custom hand-wound copper coil solenoids
Raspberry Pi 4B (4GB) — GPIO wiring
SOLIDWORKS CAD isometric view — enclosureSame features. A fraction of the cost.
Equal access to learning for visually impaired children.
Local engineering for an unmet global need.
Affordable assistive tech for every family.
