Paint Maestro 2 is a multitouch painting application I have been working on for quite a while now and about 1.5 months ago I started rewriting it from scratch. I was going to record a full demo but I encountered some technical difficulties so here is a small demo of the stencils. The application is written in AS3 and uses Adobe AIR.

(The painting responsiveness is a bit dodgy because I am currently in the process of resolving some illumination issues with my table - it is not to do with the application itself)

Wow !
great work

great concept!
How did you implement the spray? It would be great if it was with light so it would work with hands or real stencils as well.
Also, does it run on Linux? I would love to try it out on my table and give you some feedback if it is easy to get it working.
Anyway. keep up the great job!

thanks. the spray does use light. Since the spray paint is only one of many tools in the application, they are all designed to be draw with the hand.The mini spray can has an IR LED in the nozzle which turns on when you push it down. It should run on Linux because it uses Adobe AIR.

actually now that I think about it - it wont on Linux unless you are running native multitouch input. The app is built using the native multitouch events with the Windows 7 HID driver

ahh well. Your video does a pretty good job of demonstrating the idea. Are you planning to/or have publish this somewhere? I think it would be great if you could do a user study to show how intuitive it could be for people to use it.

That is excellent man, nice work. I was actually playing with the simple version on your blog haha!

That is awesome Nemen!  I made a lot of stencils in Photoshop and Illustrator and I never really thought about bringing that over to a multitouch application. Haha I am guessing you got the LED spray can from Thinkgeek? It would be great to see this on a wall where people could send and share stencils wirelessly from their phones or some other device along with creating stencils.

@Harry407 - check out Wii Spray Stencil - this is where I got the idea from. Of course I had to figure out how to make the stencils work myself. I also made the spray can myself out of an old deodorant can, some cardboard and a drilled out spray can nozzle. Just looked on Thinkgeek - I didn’t know you could buy LED spray cans! Might post some photos of mine when I get home.

Incredible! Great idea!

Very good jobs.
You are a excellent man!

I wonder if you could actually lay a stencil on the table and then spray it?  That would be even better.  I know the Microsoft Surface vision software can make vectors from objects laid on the table. It shouldn’t be too bad to get CCV to do the same thing.

I’ve actualy considered that - it would be awesome. If I had a higher resolution camera or more than one camera I’d try it. It’s hard to get a clear picture with LCD and DSI
