Super Sweet Light Graffiti

Friday, June 29th, 2007

This is a really neat example of interactive art. Its images of “light grafitti”. Using LED glowsticks, flashlights, even fireworks, combined with time-lapse photography, Light graffiti artists create a unique tagging that wraps around objects dimensionally, allowing them to tag in a way they’d never be able to with spraypaint.

 Seriusly check it out. And if we could find more information ,we might be able to replicate it..

Some Sound Stuff for Processing

Thursday, June 28th, 2007

Hey all, I have tried to go out to best buy to buy myself a camera for my 3+ old Power Book and was surprised to find that all these camera’s do not support it.  Otherthan iSight which is discontinued and even if I had the opportunity to purchase one… it would be 200 bucks.  So I’ve taken the liberty to delve abit with Sound in Processing (sorry Alicia I know I am intruding into your zone but I thought I would get acquainted with it :) )So yea so far I’ve downloaded some open source libs that enables processing to either stream / play variety of sound formats such as .mp3, .wav, .aif etc.  Going through some tutorials I created a very simple spectrum meter thingy.  What I would like to do is figure out if there is a way to isolate a specific wavelength for lets say…heavy tones… or bass tones… If we can isolate that, then we are rollin~Ok time for me to dream. Here is the link to the open src sound stuffs:

The more I think about it, the more I’m concerned about the discrepancy between the complexity of emotion words that users will be able to input via text vs. what we’ll be able to detect through the other input methods (sound, video, movement processing). This link on research identifying basic emotions gives us some options for a simpler basis of emotions to test for, which I think would be difficult enough (choose one theory, try to detect about 6 different emotions?). I feel that this might have a negative impact on the overall installation though since it’s so limiting? What do you think?

Story-telling gestures

Wednesday, June 20th, 2007

While it might be difficult to interpret gestures with simple accelerometer straps, I think it might be possible to use them in conjunction with the video processing. If there is high acceleration (the person is accelerating/flapping their arms or body around) this corresponds to an “intense” action. We don’t know whether it’s positive or negative, but we can use the facial and sound information to help derive the intended gesture. If the users are telling their emotion-filled story one at a time, putting on some straps (or however we choose to do this) should happy only during the first “stage” of the installation and shouldn’t be too cumbersome or interfering.

Technical Difficulties

I fixed the blog problem (I think). Let me know if you encounter any new problems with it. I seem to have resolved the issue (at least in Firefox)…

Sound Processing : A possibilty

Tuesday, June 12th, 2007

Alright so I was wandering abouts on this thing they call the interweb and I came across a website from the University of Helsinki. They seem to have been developing a sound processing application that is C++, which makes me happy ( I never thought that would happen) because it means that not only might I understand it , but I might be able to actually work with it to make something happen… 

So my plan is to read through their documentation see what their all about and download the application , give it a run through and see if there is anything useful there ..

Processing + MySQL = Success

Saturday, June 9th, 2007

Sup guys,

An update with my processing stuffs.
Some good news, I’ve just got processing to connect with mysql database.
We now have control to create / insert / update / read data in processing.

I have mysql database installed on my powerbook and I’ve tested it and works beautifully.

I just found out that there is a Toronto Festival of Arts & Creativity 2007 going on in Toronto from June 1 to June 10. Some of the exibits are public art and some even have human interactive projections such as PULSE FRONT by Rafael Lozano-Hemmer. I am going to hit this up this weekend and will let everyone know how it is. The idea behind it is:

the world’s largest interactive light sculpture. A matrix of light beams over Harbourfront, originating from twenty of the worlds most powerful robotic searchlights, is entirely controlled by a network of sensors that measure the heart rate of passers-by. Up to 20 metal sculptures, with embedded sensors and computers, are placed along Toronto’s harbour. Pulse readings, from people gripping the sculptures, are converted into light pulses by computers that also determine the orientation of the beams. With over 200,000 watts of power and 15 km visibility, Pulse Front blends the intimate with the spectacular in one of Toronto’s most popular public spaces.

Hey guys,I have been doing some research and really haven’t found anything that useful on sound processing…. I found this website which kind of gives you a rundown on how your averge computer system processes sound, and the available methods…. so it might turn out to be more useful than useless sometime in the future. 

I also got a return e-mail from Whitehead that suggested a site to me. It’s not techincally a book to read but he suggested that I read 6 of the publications, and to be honest most of them are pretty interesting and offer all sorts of professional publications related to interpertaion of emotive movement…

This site could be super helpful as alot of the documents on it are directly linked to existing projects that do stuff kind of like what we do. I will keep looking and try to update this more requlalry, I just plain out suck at technology forgive me.
