One fine day, while casually browsing online, I stumbled upon an ad for an AI-powered motion tracking gaming system. It instantly brought back memories of the good old Xbox 360 Kinect days. I thought to myself – my son would absolutely love playing something like this!
But then I checked the price. It was way beyond what I’d want to spend on a simple gaming cube. That’s when the idea struck me – why not build something similar myself?
With my background in Python and OpenCV, I decided to put my humble laptop’s built-in camera to good use and create a fun, interactive game for my son. And that’s how this Balloon Burst game came to life – a simple yet exciting motion-tracking game built entirely using Python.
🎯 Problem & Idea
I wanted to create:
A simple game that tracks the user’s hand or palm movements
A game mechanic that’s easy for kids – like bursting balloons by moving their hands over them
An accessible game that runs on any basic laptop with a webcam
💻 Tech Stack
✅ Python
✅ OpenCV for computer vision and palm tracking
✅ PyGame (optional) or direct OpenCV GUI for rendering the game window
✅ Mediapipe (for hand/palm detection – depending on your implementation)
🔧 Implementation Overview
Here’s a high-level summary of how I built it:
Capture video feed from the laptop webcam using OpenCV.
Detect palm or hand position in each frame.
For this, you can use OpenCV’s built-in colour tracking or Mediapipe’s Hand Tracking module for higher accuracy.
Generate balloons that rise from the bottom of the screen to the top at random x-positions.
Check collision detection between the palm coordinates and the balloon position.
If detected, remove (burst) the balloon and increment the score.
- Render all game objects (balloons, score, and detected palm marker) in real-time.
📝 Key Challenges Faced
Smooth palm tracking: Colour-based tracking is faster but less reliable in varying lighting. Mediapipe improved stability.
Collision detection tuning: Adjusting the size thresholds to make bursting feel natural.
Performance optimization: Keeping frame processing fast enough for smooth gameplay.
🚀 How to Run the Game
- Clone the repository:
git clone https://github.com/VIKASKENDRE/balloon-game.git
cd balloon-game
- Install the required dependencies:
pip install -r requirements.txt
- Run the game:
python main.py
✔️ Make sure your laptop webcam is accessible and no other application is using it simultaneously.
💡 Future Ideas
Here are some enhancements I am planning:
Adding different balloon types with varying scores
Introducing time-limited levels and difficulty scaling
Using sound effects on burst for more immersive gameplay
Packaging it into a standalone executable for easy sharing

🙌 Conclusion
This project was an exciting weekend experiment that combined my passion for coding with building something fun for my kid. If you’re learning computer vision or game development, I highly recommend trying similar projects to strengthen your skills while having fun.
I’d love to hear your thoughts, suggestions, or any cool features you’d like to see in this game. Feel free to fork the repo, play around, and contribute!
