The Problem

A gap that costs people
access to basic services

In Ghana, the Deaf community faces daily exclusion not from lack of capability — but from a communication gap that existing infrastructure has failed to close.

🏥

Healthcare

Deaf patients receive misdiagnoses because doctors cannot communicate with them. Hospitals have no interpreters on staff.

🎓

Education

Deaf students fall behind because teachers have no way to bridge the language gap in real time during lessons.

💼

Employment

Deaf job seekers are turned away not because of skill, but because basic workplace communication is impossible.

🏛️

Public Services

Interacting with government offices, banks, and emergency services is a daily barrier with no scalable solution in place.

How It Works

Five steps. Under 200 milliseconds.

From hand to text — entirely on your device, entirely in real time.

01
Camera Capture
30fps live video from front or back camera. Frames preprocessed to 256×256 RGB.
02
Hand Detection
MediaPipe detects and tracks 21 3D landmarks per hand in real time.
03
Gesture Segmentation
A sliding window algorithm isolates discrete signs from continuous motion.
04
AI Classification
Landmark coordinates fed into a CNN + LSTM model trained on GSL data.
05
Text Output
Recognised signs rendered live on screen. Read immediately. Copy anytime.
