Learn the NGT alphabet with your webcam

Name: SignSee
Author: SignSee

SignSee teaches Dutch Sign Language, starting with the alphabet. It watches you fingerspell a letter and tells you right away whether you got it right. Today it covers the 22 static letters; more of NGT follows.

See it working

A short recording of the app recognising letters as they are signed. Silent, so you can watch it anywhere.

Read a description of the video

The recording shows the SignSee practice screen. On the left is the alphabet with the current target letter highlighted; in the middle is the live webcam view; on the right is a written hint for the letter together with an illustration and a photo of the handshape. The learner raises a hand into the webcam view and a green outline tracks the hand, labelling the letter the model is reading and how confident it is. When the handshape matches the target, the webcam view is outlined in green, a “Great sign!” message appears, and a button offers the next letter. The clip works through the letters A and B this way. It runs for about seventeen seconds and has no sound.

How it works

Show your hand

Hold the letter in front of your webcam. Nothing is uploaded.
The model reads it

A machine learning model works out which of the 22 letters you are making.
You get an answer

Correct or not, you see it straight away and can try again.
Progress is kept

You can see which letters you have learned and which need practice.

What makes it different

You practise, not just watch

Most sign language courses are video lessons you sit through. Here you make the sign and get an answer about your own hand.

Built for NGT

Recognition tools almost always target American Sign Language. SignSee is trained on Dutch Sign Language.

Accessible from the start

Keyboard use, contrast and screen reader support were part of the first design, not a fix added later.

Roadmap

Where SignSee is now and what we plan next. Dates and later stages are still being decided.

Stage 1

Done

The alphabet

The 22 static NGT letters with live feedback while you practise.
Stage 2 · October 2026

In progress

First dynamic signs

Four signs that involve movement, and a model that can read moving input rather than still hands.
