Fluid Boundaries:Video Documanetation
Video Documentation of the reaction and interaction of audiences day2, day3
Finally, I’ve made the ocean as large as I want to. There was no way I could make larger image within short throw distance ( in 3m ) without using fixed zoom lens( $1500 )for my projector.
Lastly, I am willing to test with sand screen for the final demonstration.

I was going to use this setup for exhibition. However, it was not enough to make 4m X 3m virtual ocean on the floor. I’ve decided to purchase zoom lens-022.
I am willing to hold my exhibition in Dean’s gallery.
This is the documentation of my 1st. demonstration. I put the maxmsp codes ( motion detection, 3d nerb ) together and demonstrate in the real space at Pratt E2. It was very effective and interesting to participants. But, more than that I was pleased to figure out what do I need more for the real exhibition.
For the audiences motion detection, I am going to use this ( Maxmsp patch ). It helps detecting the movement on the screen and adjusting sensitivity as well.
When you use the wide lens for motion detection in any reasons such as limited exhibition space, you can see the image distortion ( Image 001 ) on the each edge of video image. To prevent this, I’ve used lens correction Patch ( Thanks to Liubo )
(Image 001 )
When you open this patch, you can see “CHANGE HERE”. You can change the number depending on your lens or camera. Then, you can see the straight image like ( Image 002 ). In my case, I put ‘0.4′ instead of ‘0′.

Now, It’s time to test whether camera only can detect audiences movemnt except projected image.
I’ve tested projected images + Audiences movement + camera ( no IR coating camera + developed film to block the visible lights) + Infrared illuminations
I’ve tested Infrared Illumination without projected image in order to know ” How many IR Illuminations do I need ” covering 3mX4m. As a result, I’ve figured out that I need at least 9 IR Illuminations for the real project. When you see the video below, you can see how does it look according to the IR Illuminations in the dark.
