The build
Step 01
Track the hand
Run a hand-landmark model.
Step 02
Read finger positions
Get the joint coordinates.
Step 03
Define gestures
Map positions to signs.
Step 04
Recognise
Show the detected gesture.
Working Principle
The model finds your hand's joint positions; comparing finger angles to defined patterns identifies each gesture.
The science behind it
A closer look
Landmark detection gives precise joint data, so simple rules on those points can recognise many gestures.

Variables to test
- 1 Add a new gesture — reliably detected?
- 2 Test both hands — does it generalise?
