What is AirCanvas?
AirCanvas is a fun app that lets you draw on the screen using just your finger — but without touching anything! All you need is a webcam. Just wave your finger in the air, and it turns into a magic brush.
How Do You Use It?
The camera looks at your hand and finds your pointer finger. When you move your finger, the app draws lines on the screen, just like a pencil. You can choose different colors, make your brush bigger or smaller, and even erase if you make a mistake.
What Makes It Cool?
You don’t need to click or press any buttons. You can draw, erase, change colors, and save your artwork just by moving your hand in front of the camera.
How It Works
- Webcam: The app uses your computer’s camera to watch your hand.
- Hand Landmarks: It finds important points on your hand like your fingertips.
- Computer Vision: This is how the computer “sees” your hand and understands where it moves.
- Drawing: When your finger moves, the app draws a line from point to point — just like a crayon!
