move your pointer over it — the hand follows you
Real time, no edits — a bare hand and a webcam. No stylus, no headset, no extra hardware.
An air canvas is a drawing surface you control with your hand instead of a pen. A camera watches you, software follows your fingertip, and the path it travels becomes a line on screen. There is no tablet, no stylus, and nothing to touch — you draw in the air, and the drawing appears in front of you.
The idea began as a computer-vision exercise: find a hand in a video frame, map its coordinates to a screen, and paint wherever the fingertip goes. AirVA is that idea finished — hand tracking that runs inside a browser tab, a pinch that starts and stops the line, and a canvas that keeps everything you make.
If you have ever used a mouse, you already know how it feels. Point to move. Pinch to draw. The only difference is that nothing sits between your hand and the picture.
“MS Paint, but the mouse is your hand and the mousepad is thin air.”
Also called: air drawing, air writing, a virtual painter, hands-free drawing, gesture drawing, or simply drawing on your webcam. Same idea, different names.
No depth sensor, no glove, no marker to hold. Three things happen, many times a second, for as long as your hand is in frame.
The ordinary camera above your screen is enough. Frames are read inside the browser and never uploaded — there is no server in this loop at all.
Wrist, knuckles, joints, fingertips. Together those points describe where your hand is, how large it is on screen, and which way it is turned.
The gap between thumb tip and index tip, measured against the width of your own hand, is what says “draw”. Close them and ink flows. Open them and it stops.
Measuring the pinch relative to your hand rather than in raw pixels is the detail that makes it usable. It means the same gesture reads the same whether you lean toward the camera or sit back from it, and whether your hands are large or small. That is also why there is a short calibration when you first open AirVA: it learns the shape of your pinch once, so the line starts exactly when you meant it to.
The phone apps in this category run $0.88 first-week trials that quietly become $10 a week — about $40 a month — make you pay to upload your own image, and play two ads before you can draw one thing. AirVA is a browser tab: no subscription, no trial, no account, and no ads between you and the canvas. Open it, allow your camera, draw.
It's a website, not an app. Nothing installs.
A short one-time calibration learns your hand.
That's the whole interface. Save or record what you make.
Most air-canvas projects stop at a coloured line following your finger. This is the version that kept going.
Marker, neon glow, velocity ink that thins as you move faster, rainbow gradient, mono and sparks.
Pan and zoom with your hand. The canvas has no edges — the drawing keeps going wherever you do.
Save a full-resolution image, or record the whole thing and export a 2×/3×/5× timelapse for Reels and Shorts.
Every stroke is data, not pixels — so undo removes exactly one stroke, however long it was.
Pinch to draw, two fingers to pan, three to open the menu. Your hand is the whole controller.
Hand tracking runs inside your browser tab. There is no upload path for camera frames in the code.
Most air-drawing demos track your hand. AirVA is calibrated to your hand — a one-time setup tunes pinch detection to your fingers, which is the difference between drawing and fighting the cursor. Strokes are data, not pixels: undo anything, snap a shaky circle into a clean one, grab a drawn line and bend it. When you're done, keep what you made — export a photo or a video of your drawing appearing stroke by stroke. Everything runs in your browser; the camera feed never leaves your device.
Air drawing is not a better pencil. It is a different thing entirely — the drawing happens where people can see you make it, which turns out to matter more than precision.
Circle the thing you are talking about while you talk about it. In an online class or a recorded lesson, pointing with your hand reads as attention in a way a cursor never does — and nobody has to watch you fumble for a stylus first.
The gesture is the content. A hand pulling a glowing line out of thin air holds a viewer through the first three seconds, which is the whole game on Reels, Shorts and TikTok. Record it, export a timelapse, post it.
Run it as a browser source in OBS and annotate over your own camera feed live. Highlights, arrows, a quick diagram — drawn mid-sentence, without cutting away to another window.
Some of it is just delight. Kids get it in about four seconds, and the first reaction from almost everyone is to check whether there is really nothing in their hand.
Drawing in mid-air has no surface to brace against, so it will never be as precise as a pen on glass. It is expressive rather than exact — and a few small things make a real difference.
The camera needs to see your fingers, and a bright window behind you turns you into a silhouette. Face the light. If the room is too dark, AirVA will tell you rather than sit there failing quietly.
Tracking reads your hand as a whole shape, not just the fingertip. If your wrist drifts out of view, the line gets unsure. Sit back a little and give yourself room.
Long strokes come from the arm; small wrist movements wobble. It is the same advice whiteboard teachers and sign painters give, and it works here for the same reason.
Touch your fingertips, do not squeeze them. Calibration learns a light contact, so a firm grip lands outside what it measured and the line starts late.
Still stuck? Open the canvas and try it — the thing answers faster than reading about it does.
Try it FreeAn air canvas is a drawing surface you control with your hand instead of a pen. A camera watches your hand, software follows your fingertip, and the path it travels becomes a line on screen. There is no tablet and no stylus -- you draw in the air, and the drawing appears in front of you.
Yes. No trial, no subscription, no credit card, no account. It runs in your browser.
No. The hand tracking runs inside your browser tab. There is nothing to download or set up.
No. The camera feed is processed on your device, in your browser. Nothing leaves your computer.
Yes. It works on phones as well as laptops. On a phone, hold it upright and leave your hand some room in the frame; a laptop gives you a larger canvas and an easier reach to the tools, but you can draw on either.
Yes. A lot of visitors arrive here from an OpenCV build that is fighting them. Use AirVA for the demo itself -- it runs on any laptop with a webcam, with nothing to install and nothing to break on the day.
A laptop with a webcam, a browser, and a hand. Decent light helps.
Yes -- export as an image or record a video of the drawing appearing stroke by stroke.
Your webcam sends pictures to your browser, software locates 21 points on your hand in each one, and the distance between your thumb tip and index tip decides when to draw. Because that distance is measured against the width of your own hand, the same pinch works whether you lean toward the camera or sit back from it.
No. The ordinary camera built into a laptop is enough. There is no depth sensor, no glove, no coloured marker to hold, and nothing to plug in.
It needs enough light to see your hand clearly. Face a light source rather than sitting with a bright window behind you. If the room is too dark, AirVA says so instead of failing silently.
A tablet wins on precision -- it has a surface to brace against and a pen with a fine tip. Air drawing has neither, so it is expressive rather than exact. What it gives you instead is that your hand is visibly making the drawing, on camera, with nothing in it.
No. AirVA is a website. There is nothing to install, no account to create, and no app store involved -- you open a tab and start.
Open the tab, allow the camera, and draw a line in the air. If it doesn't feel like your hand, we want to hear about it.
