AI Activity

Magic Sketchpad

Magic Sketchpad is a website that uses Artificial Intelligence (AI) to help complete your drawings. When you start drawing something, the computer guesses what you are trying to make and adds to it.

Objective: The aim of this activity is to help students understand that AI can learn from drawings and try to guess what we are making.

As students draw, they will see how the computer watches their lines, makes a smart guess, and then helps complete the picture.

1 Open the following website with the help of your teacher: https://magic-sketchpad.glitch.me

2 You will see a blank white area in the centre.

3 A list of object names appears at the top showing “cat,” “car,” “tree,” etc. options.

4 Choose one of the words from the list. For example, select “flower”.

5 Start drawing in the white box using your mouse. Draw the first petal of the flower.

6 Watch what happens! The computer will start to complete your drawing. It is guessing what you are drawing and helping you finish it.

7 If you want to try again, click on the “Clear” button to erase and start a new drawing.

8 Try drawing other things from the list like a house, sun, or dog!

Have you ever asked a speaker to play a song or talked to a toy that answers back? These are examples of machines using something called AI.

Artificial Intelligence

AI stands for Artificial Intelligence.

It means making machines smart so they can do things like understand your words, follow your instructions, or even learn from what they see or hear.

AI Around Us

• Talking Toys: Some toys use AI to understand your voice and respond with sounds, songs, or even short sentences.

• Robot Helpers: These machines help us with daily tasks at home. They can clean floors, cook food, etc. They do work in the same way as a human does.

These machines do not think or feel like humans, but they can be trained to do certain tasks.

AI devices are all around us. There are many types of machines that use Artificial Intelligence (AI) to perform tasks or respond to us. Some examples of such AI devices are:

• Smart Speakers: These speakers respond to your voice commands. They use AI to understand your voice commands, like when you ask them to play music or tell you a story.

• Selfie Magic: Some phones use AI to edit your selfies. The AI can adjust lighting, smooth out backgrounds, or add fun filters.

• Learning Games: These are educational games that you play on your computer. Some of them use AI to adjust the difficulty level as you play. For example, AutoDraw!

Fun with AI: Using AutoDraw!

Let us perform the following experiment to understand how AI uses computer vision to see and understand things.

Objective: AutoDraw is a fun and free online drawing tool based on computer vision. It uses AI to guess your drawing and provides suggestions to turn your scribbles into complete drawings.

Follow the given steps to explore how this application works.

1. Visit the link: https://www.autodraw.com/

2. The following window appears.

3. Click on the Start Drawing button.

4. Now, select the AutoDraw tool from the left panel.

5. As soon as you begin to scribble in the drawing area, the AutoDraw tool will make use of computer vision to guess your drawing.

6. Choose the drawing from the list of suggestions provided in the top bar that most closely resembles the one you plan to create.

7. You may further customise your drawing by using the Shape tool to draw a circle for the eyes and fill in colours using the Fill tool.
