Google QuickDraw & AI That Sees Drawings! ✏️

A game of 50 million doodles, Google Lens magic, and how AI learned to see YOUR sketches

Google QuickDraw & Drawing AI! ✏️

Google QuickDraw: The Coolest AI Experiment 🎨

Try it now: quickdraw.withgoogle.com

Here's how it works:

  1. You get 20 seconds to draw something (like "cat" or "bicycle")
  2. AI watches your drawing appear stroke by stroke
  3. Before you're finished, AI guesses what you're drawing!

It's hilarious — especially when it confidently guesses wrong 😂

How QuickDraw Was Trained

Google needed training data. They made a GAME!

Millions of players drew 345 categories of objects Result: 50 million doodles collected! AI learned: - Cats have two pointy ears → horizontal line → four legs - Trees have a triangular top → vertical trunk - Houses have a square + triangle on top

Even though everyone draws differently, AI finds the common patterns in how HUMANS draw things!

📱 Google Lens: Point and Discover!

Google Lens is computer vision in your pocket. Point your camera at:

| What you see | What Lens does | |-------------|---------------| | 🌸 Flower | Identifies the species + growing tips | | 📦 Product | Finds where to buy it + price comparison | | 📝 Maths problem | Solves it step by step! | | 🍽️ Food | Names the dish + finds the recipe | | 🦋 Animal | Species name + fun facts | | 📖 Text in another language | Translates it instantly! |

🌿 The Plant App That Saves Lives

An app called PlantNet used computer vision trained on millions of plant photos to help people identify wild plants.

This genuinely saves lives! Before, hikers who weren't sure if a berry was safe would have to guess. Now they can take a photo and AI identifies it instantly.

✏️ How AI Recognises YOUR Handwriting

When you write on a touchscreen:

  1. AI tracks the movement path of your finger/pen
  2. Compares the shape to thousands of examples of each letter
  3. Recognises it even in your messy handwriting!

This technology is used in: iPads, drawing apps, Google Translate (point at handwriting), bank signature verification.

💡 Try This!

Open Google Lens (it's in Google Photos or Google app) and point it at:

  • A book cover (it'll find the book online!)
  • A plant in your garden
  • A maths equation in your textbook

Computer vision in your hands! 🤩
