First version of the Braitenberg vehicles

My thesis at CIID is about objects with personality and the different ways there are to implement "artificial" personality in otherwise stupid objects. As part of my research I have decided to take a closer look at Valentino Braitenberg's work with synthetic psychology in the beginning of the 80's. Especially his investigations in the book "Vehicles: Experiments in Synthetic Psychology" where he designed the rather famous Braitenberg vehicles. The vehicles are extremely simple electronic objects, that seem to show a specific personality from their actions. The interesting thing is, that they are in fact extremely stupid, but because we (humans) only look at their actions without knowing why they act as they do, we tend to project our own logic and reason to them and thereby give them a personality that they actually don't have. It sounds a bit complicated, but actually it isn't - it's just because I can't explain it properly yet :) I decided to base them on Arduino, though it might be overkill - the reason I did it is to keep flexibility, so that I later can upload more advanced firmware to the bots. Here's a photo I took of one of my boards - unfortunately I put it upside down!

Anyway, of course I also snapped some photos of the first vehicle and it's half-finished sibling today. Here they are:

Rock is the new swivel

I've wanted to write this post for about 6 months now. And now I'm finally doing it! Hooray! One of the first quick foundations courses we had was with Massimo Banzi and Gwendolyn Floyd, where we explored and played with physical computing. First week we played with the basics of Arduino and serial communication. That's where I built a couple of small (and stupid, but cute) robots with Jason. Second week I worked with Eilidh and Ashwin on a self-chosen concept within the realm of physical computing and networked objects. We decided that we wanted to design for "Guerilla free-time", in other words the project was a comment on how technology that is supposed to give us more free-time, actually ends up stealing our time, because everything becomes more and more efficient.

We set our context in busy office environments where people often isolate themselves in their cubicles, staring at the screen all day. The only times they take breaks is when they walk to and from the coffee machine or when they have lunch. We knew that we probably couldn't convince people to take extra breaks, so we decided to tap into the existing "break-facilitator" of the workplace: the coffee machine. Getting a cup of coffee usually takes less than a minute, and then you're back at your desk. We wanted to extend that time to a little more than a minute.

We decided to make a coffee machine that requires you to take a break, to get your coffee. We did it by hacking a coffee machine and a rocking chair, so that when you sat down in the rocking chair and started rocking, the coffee machine would start brewing you a nice cup of coffee. In addition to that, you would get a relaxing Gilbert O'Sullivan tune playing - and working as an indicator for when your coffee is ready. If you stop rocking or leave the chair, the chair will warn you by fading out the music. If you still aren't rocking, the coffee machine turns off.

We did that by making a special plugboard, that could be controlled wirelessly (Arduino and Xbee) that the coffee machine was plugged into. Under the chair we put another Xbee equipped Arduino with an accelerometer, hooked it up with a hacked El-Cheapo mp3-player and a small Nokia speaker.

First Skills Upgrade

Ouch. This stuff actually happened before Christmas... I'm not that good at updating regularly. I'll be back soon with a post about the TUI course we just finished, and hopefully that will make this site a bit more up-to-date. Well, the last week before Christmas was dedicated to "Skills Upgrade"-courses. The class was split in two, one half was working with James Tichenor and Joshua Walton from Rockwell Group, on different proposals for interactive installations for SAS Royal Hotel in Copenhagen. The other half (which I was part of) worked with games and computer vision which was taught by Yaniv Steiner.

We spent the week experimenting with different small things within the field of computer vision. The first project we did, was the game "Style Wars" - a reaction game, where you use your hand as the game controller. The game is very simple: you and your opponent face each other like in a classic western duel. When you hear a specific bang-sound, it's all about being fastest to draw your gun (gun = pointing hand). If you react too early (before the right sound), you lose. The name "Style Wars" doesn't really make much sense - but the reason for the name is, that in the game, one player has the role of a flamenco-dude, the other player is a hip-hopper. I am assuming that it's common knowledge that flamenco-dancers and hip-hoppers don't get along very well.

Dave Mellis captured me and Erlend dueling in the video above. After making "Style Wars" which was based on simple Flash-motion tracking, we moved on to reacTIVision, where we made our own lo-fi reactable with a standard camcorder, a window and a desklamp. We used the table for testing and having fun with both Flash and Processing.org. One of the applications were a "body-mixer", that made it possible to build your own custom CIID student (or freak) by mixing the legs, torsos and heads from all of us. The controls were three "dials" with fiducials underneath.

I uploaded some pics from the skills upgrade on Flickr - you should check them out if you want to see some of the other cool stuff people made, like the Dancing Game, for instance... The thumbnails are here:

Video prototyping - KeyLess

Here comes an update - only a week late! The second foundations course was a short 1-week course in video prototyping. Video prototyping is about sketching a product or service concept using video as the medium - the outcome is not a polished video, but a video showing and explaining the overall features of the service in short time. The course covered the process from storyboarding and making props to shooting and editing using basic tools (like iMovie). This video was shot and edited in 2 days. Before that an even more low fidelity and low resolution version was made. The video prototype is about the "KeyLess" service, a concept that the whole class worked with (it was open for interpretation). KeyLess is basically a service for people who often forget or lose their keys - just call Keyless, and you will have a set of spare keys within 30 minutes. As the video is not an ad, but a concept description, you will also see shots of the verification process at the KeyLess office as well as agreeing on a meeting place (in this case Trianglen). It took some effort convincing the 7-Eleven girl to be in our movie, but besides that everything went smooth.
