Introducing TactTool

2008-08-08T22:49:19Z

Nothing like a good vacation to clear the mind and the schedule. Not happy with the current state of computer vision apps for multi-touch and doing a bit of research, I've decided to embark on building TactTool, another multi-touch framework. Th...

Time for some crazy fiducials

2008-07-27T06:33:32Z

I'm excited that I was able to get an account at Shapeways. It is a 3D printing service that will allow me to create some funky cold fiducials (yes, cheesy 80's reference) for my DI table.

Below is a screeny of an OpenCV port to Processing. Blob detection in under 100 LoC. The top two screens are raw camera output, the bottom left is the background subtraction image and the bottom right is the processed blob detection with x/y coor...

Flash real-time

2007-11-23T18:26:14Z

I'm testing out Pacifica, Adobe's Flash VOIP library, and I have to say, "it works as advertised", meaning the demos shown at Max and other events are true to form (I'm under NDA so I can't say much more). With RibbitPhone, Red5, Smart Fox Server...

Ribbitphone development

2007-09-17T15:02:50Z

Ribbit Phone, the VOIP library for Flex/Flash, is awesome and simply amazing. In less then 5 minutes, using the sample code, I was able to create a Flex project that made and received phone calls! Wait, it gets better. Not only can I make and r...

I'm Baaaack

2007-09-08T04:42:01Z

I know I know, I have been away too long. My startup was acquired and now I'm working for the MAN. I'm still working on multi-touch software (using diffused illumination now instead of FITR) but what brings me back to blogging is the anticipatio...

ECMA - the new four letter word

2007-04-13T18:47:50Z

When something essential is purposely flawed. Derived from the standards body that regulates javascript/Jscript and Actionscript3, the most widely used client side programming languages on the Internet today. I've been asked, "What programming ...

Actionscript port for Silverlight?

2007-04-11T00:49:51Z

I'm a little late to the game but Microsoft announced the release of their CLI. With the release of Tamarin, I sense an Adobe v. Microsoft fight which hopefully will result in the ability to compile AS3 code to a .NET compatible binary? I'm sure...

Blob Detection working in Flash

2007-04-08T07:33:16Z

Nothing major but I am too excited! I have simple blob detection working in AS3. The swf is less than 5k and it works better than I expected (I guessed at values and got pretty much spot on). I know each slate is going to have different values...
