Show HN: Airdraw (opens in new tab)

The demo gif in the github, https://github.com/arefmalek/airdraw, is pretty awesome. Thanks for postin the code as well. Perhaps put that demo in home page of the website

my father is deaf and mute, particularly the Pakistani sign language, one particular utility i see this can be really useful for is if the model can be trained on detecting different sign languages, then it would become possible for live translation to happen and in a distant future all people like my dad can talk with each other beyond their small communities. I don't think something like that exists.

This is a delight to play with; thanks for sharing!

One slight UX suggestion: Consider a "start" button before making the camera request. Permission prompts are blocking modals on Safari (unlike Chrome where they're a pop-over from the toolbar), so the user doesn't necessarily have context if it's on page load!

Pretty cool and intuitive. I think translation would be more natural between the thumb and index finger, as if you were closing around to pinch the squiggle.

Also, look at the many JS drawing samples out there - it's very simple to smooth out the lines - either by adding a small delay to calculate the curves on the fly, or by snapping to the curve when the line stops.

If you unexpectedly get balloons in your video, here's why: https://support.apple.com/en-us/105117

Waited 20 seconds - stuck at “model loading.” Closed the page. iOS 17.2 with safari.

I had a lot more fun with that than I expected great work! I found my finger maneuvers not crisp enough to do anything with real detail.

One idea I immediately had was to use a key on the keyboard (if not on mobile of course) as triggers for draw, hover, erase, etc. You could also control different colors that way, possibly even draw generated shapes like circles and rectangles (press 'c' to start a circle, then use your finger to drag out the size, stop with 'c' again).

and if you want to get really advanced, allow rotation of the drawn object and then choose a new plane to draw on.

I was building something really similar here https://ablepaint.dreammachine.one/ !

Regarding the HN post. This is the first time I have seen a clickable URL in an OP.

Did something change? It's nice not to have to copy and paste the URL.

Zot Zot Zot! Nice to see another anteater here!

It would be really helpful if you could make signatures (like signing contracts/etc).

You really don't want to have white text on light grey buttons.

Fun little thing otherwise!

Okay that's really fun. Awesome interface. Works on latest FF on Win 10.

pretty cool, main thing is you really want to do all your drawing above your shoulders. Below your shoulders you start rotating your hand and it loses track.

Nice. The interface looks still complex to use to me

would like this on https://excalidraw.com/

peace + pinky finger is quite difficult for me to do, i would prefer a different gesture for erase if possible

Pretty neat :)

This is really cool, nicely done

I acknowledge the effort you put into this, but I'm curious about the practical application or purpose behind it.

Surprisingly intuitive :)

wow. dude you have an awesome idea. Will definitely try it.

Great works!

patent this now
