Marketing yourself

If you’re a student about to finish and need a job. And you have the possibility to speak to thousands of people within your industry at a huge conference. Then this T-shirt is really perfect…

I would have put in my web site instead of “Contact me for my CV”, but still a great idea.

Mobile phone tennis

…or, augumented reality tennis. That’s what the creators of this nice application want to call it.

Mobile phone Tennis
It’s a game for Symbian based phones like the Nokia 6630, 6670, N series etc. The application use the camera in the phone to read the pattern on the table. It then analyze this stream of information and renders a tennis court on the screen of the mobile. When you move the mobile in any direction the tennis court will adjust. Meaning that the phone works like your tennis racket.

It uses both sound and vibration in the phone to give feedback to the user in addition to the actual game on the screen. The game is synchronized between the phones using bluetooth.

I’m at Siggraph 2006 and will try to post some of the stuff that I find interesting through the week. No particular order or focus. Just notes along the way during this highly interesting conference. You can read more about Siggraph over at the official ACM Siggraph site. To put it short, this annual conference is the world’s biggest conference on computer graphics and interactive techniques.

So for my first little note. I just finished a session by Dr. Aude Oliva, Antonio Torralba and Philippe G. Schyns. It was about what they call hybrid images.

Images that change based on the distance from where it is viewed. Have a look at the two pictures below:

Angry and nice
Pictures copyright © 1999-2006 Aude Oliva & Philippe G. Schyns. MIT

Now step away from your computer screen while looking at the pictures. Depending on the size of your screen and the quality of your vision the pictures will change at a certain distance. For those of you that is just too lazy to step away from the screen I can simulate this by simpy reducing the size of the image. This is a small version of the exact same image:

Nice and angry

Suggested uses are commercial billboards that change depending on the distance to the viewer. and fonts that can only be read at a close distance to avoid people reading “over your shoulder”.

You find more examples and information over at the GALLERY OF HYBRID IMAGES.

More videos from Siggraph 2001

This year’s Siggraph starts in less than a week. It’s time to finish off my little series of videos from the 2001 conference and make room for new and interesting stuff from Boston next week.
First, another computer game controller experiment. You control the game by moving the different shapes in front of the screen. Link to video.
And another pretty advanced multi player computer game. It’s 3D and is controlled by sensors in the 3D glasses and a special glove. Link to video.
Then a little bit of art. You sit down in front of the screen with a headset with a microphone. Say a word, for example “elephant” and the system starts finding pictures of elephants on the internet and let them fly over the screen. Two persons can play at the same time. In each end of the screen. Then you can have pictures of elephants flying towards pictures of dogs… Link to video.
Then some physical movement communicated through the internet. Place the sensors somewhere, connect to the internet and place the second set another place on this planet, also connected. Move one of the sets and the other one will move exactly in the same manner.

Very nice if you want to wave goodnight to your grandmother in Japan through movement with a robot teddy bear. Link to video.

And last but not least, the scary vision. There is no water left on earth and all you have is this virtual shower. Fortunately, my camera didn’t get wet. Link to video.

Magnetic fluid art installation

Protude Flow
Protude Flow is one of the most amazing art installations I have ever seen. Another clip from my archive of videos from the Siggraph conference back in 2001. It is impossible to communicate how it was to experience this thing live through a video. The installation was made by Sachiko Kodama and Minako Takeno. It is a pool of magnetic fluid with one very powerful electro magnet above it. The magnet is controlled by the sound in the room through a microphone.

Link to video on Revver.

The experience was something like “this has to be trick photography“. But you are there in the room and it is real…

Amazing floating words

While preparing for Siggraph 2006 i went through my archives and found a couple of videos from my visit to Siggraph back in 2001. Some of the technology and art installations are still pretty amazing so I have decided to post a series of videos from that conference.

This one is from the art exhibition. The system consist of a couple of computers, a projector, a camera and a pool of water. The projector and the camera is mounted directly above the pool. One computer renders the characters and project them in the pool. Another computer is analyzing the video feed from the camera and control the animation of the words on basis of the movements of the elements in the picture. One is used to move the characters and the other one is used as an eraser.

Link to the video on YouTube.

You speak into a microphone and letters start to drip out of the funnel. Then you can have fun lifting the letters up, moving them around and erase them.

These kinds of alternative methods of controlling computers are quite interesting. Again, I have to think about Brian Eno and the wish for more “africa” in computers. Mentioned here at before. You also find some thoughts over at

If you want to follow the rest of my videos from Siggraph 2001 I recommend subscribing to this blog through your RSS reader or through my email update. You find all the information you need here.
