hand gestures, reaction images, and drawing in the air.

about the project

An Instagram reel used hand gestures to trigger reaction images, so I made a 67 detector and an air-drawing program with OpenCV.

I showed the project at my IB Theory of Knowledge exhibition in November 2025. It was voted the winner, and I presented it to 150 people in the library.
