About a month ago I decided that it was time to do something geeky, so I looked at a couple different projects that I could do and picked a multi-touch system. I didn’t want to do the standard FTIR system because it seemed like a lot of people were building them so I decided to do it with lasers. I stumbled across this http://arbi.trario.us/2008/11/02/diy-laser-multi-touch-table/ tutorial and set on my way.
The first step was to do a lot of planning. How big should it be? What do I need to build it? How am I going to do something like this when I don’t know anything about the technology? Well, I decided to go ahead with it based on the list of parts that were in that tutorial plus a couple things of my own.
Once all of the parts were ordered, I decided to spec out and start building the box to house the screen and eventually the projector. Here are a couple pictures of the construction process.
Once that was built enough for me to start on the electrical aspects of the screen (and once all the parts arrived), I started on that. Cut out the corners of my acrylic and struggled with my first ever electrical circuit. Mounted the lasers in some air-drying clay and plugged it in. It worked on the first test (with a lot of little adjustments) and I have the following video to show you my first test.
There is still a lot to do with the setup, including adding the projector and a screen to touch, but it is on its way and I am very happy with it thus far. Stay tuned for more updates in the coming weeks.
In late January I started a project called PaperFace, it is a giant project that is an attempt to build a web-based front end for Papervision. It would allow designer to start harnessing more of the 3d power on the web, plus it could make creation of Papervision 3d scenes much quicker for developers as well.
I quickly realized that I don’t have enough time to make this thing on my own, but being stubborn, I tried anyways. Well, I haven’t had time to even really think about it for over a month now but would like to get back at it buy paxil.
What I have decided to do is to try and create a team of 3 or 4 developers to try and get this this off the ground and working, because I really feel that it would be a benefit to the Flash community. If you would like to help out, I am looking for a couple people that have experience in both Flex and Papervision viagra generique.
Here are some of the areas that we need some specific help with :
If you are interested, you can check out www.paper-face.com to see the app and email me at firstname.lastname@example.org and we can get going on this. One thing to note is that there is no compensation for the work done on this project but I would like all involved to take it seriously. It will be a good learning experience and hopefully a helpful tool for the industry.
Augmented Reality is a technology that allows you to superimpose images into real-time environments. For the purposes of this tutorial, you just need to know that it reads a marker (shape/symbol), interprets the angle and size of that marker and then allows you to place objects at that size and position on the screen (or whatever your medium is).
You will also need FlashDevelop or another Actionscript editing tool. In this tutorial I am going to be compiling my code directly from FlashDevelop, but feel free to use the compiler/method of your choice.
After all of the tests and playing around that I have done with face/motion detection in Flash and Processing Quasimondo posted an optimized version of the OpenCV port to AS3. This is something that I have been waiting for someone to do for quite some time. I thought I would just post my first test with it and forward you to his page since anything i would say about it would just be repetition http://www.otcsildenafil.net/.
In my example, I just slightly modified Mario’s class to allow for an image to be placed instead of just a box being drawn. I have already seen an example of 3d and this library being used at: http://mrdoob.com/blog/post/643
This may be a little bit pre-mature, but I would like to announce the launch of a new site. It is called PaperFace.
PaperFace is a graphical user interface for Papervision 3D. The goal of the app is to build out 3d scenes without the need to write all the initial code. I am hoping to build it to a state where designers can come in and build a fairly complete scene and export the code to someone that can do something with it. Please go register and tell me what you think. Check out the forum on the site, and post any feedback you may have.
The app is no-where near completion, but I thought it would be good to get some thoughts on it throughout the course of development. Plus, now that it is live it puts a little bit of extra pressure on me to work more on it.
