Nick Inzucchi – FaceOSC

by nick @ 2:25 am

Good Evening

I used FaceOSC to generate behavioral portraits of four presidents delivering dire addresses to the American people. Scan-lines represents the facial features of Obama following the BP oil spill, G.W. Bush responding to 9/11, Clinton apologizing for lying to congress, and G.H.W. Bush announcing the invasion of Kuwait. Each president has lines describing the X-Y motion of the eyebrows, eyes, nose, mouth, and jaw over time. I was interested in the particular gaze they adopt staring straight out into the lens. I played with different kinds of digital mark-making until settling on the small vectors above, finishing the whole piece in Photoshop to give a dire EKG-like effect.

Facial System

[vimeo=http://vimeo.com/35555418]

I used the data from FaceOSC to generate a simulation of a planetary system. The idea is that everyone’s face should generate a slightly different planetary system. Often the orbits are not stable, so you can watch one of your eyes or your mouth slingshot around the sun and achieve escape velocity.

Each planet represents a facial feature, such as an eye, or eyebrow, or mouth. The masses of the planets as well as their distance from the sun are based on the distances of those features as measured by FaceOSC. Initial velocities of each planet are based on the face’s preliminary orientation, and the view translates and scales with the face; so you can get a closer look at your solar system by moving closer to the camera.

Heather Knight – Face OSC

by heather @ 2:05 am

An antagonistic photon-cannon whose main directive is to cause damage to your eyesight.

[vimeo=http://vimeo.com/35554377]

Please enjoy my audio description. In a department where 50% of our funding comes from the military and some of our most exciting innovations are in the war zones, I decided to use FaceOSC to attack our own citizens. Technology can be used for good or evil, for suspicious or silly. Several of our drones have recently been reassigned from the Middle Easy to domestic skies in the name of law and order. Opensource software could easily bootstrap the development of creatively nefarious systems. Vigilance.

At first, I though I’d build this for real, using servo-motors to hone in on human faces and laser pointers to threaten mild damage. Then I fell victim to the playfulness of particle systems. The logo for this project would be a bullseye with a winking orb at the center, complete with luscious lashes.

I kind of approached this part of a project in a different way. Instead of trying to come up with an algorithm to derive the art piece, I decided to turn it into one derived from the user through the use of sound. Though it’s obviously not perfect and is missing a few vital components, it more or less kind of resembles the original 13/9/65.

Jonathan – Face OSC

by jonathan @ 1:48 am

I wanted to have a little fun with this part of Project 1. I took a quick picture of my friend Ethan, and used his image as the little avatar in my game. My aim of this program was to just get a bit familiar with how OSC functions as well as how the library Face OSC works. The object of the game is to catch the little balls in Ethan’s mouth controlled by the movements of your own mouth. Though this interaction is nothing special, my mental image of people’s opening and closing mouths while sitting at their computer completely engrossed with the game was especially comical, which in the end was a good enough reason for me to make it. Overall the face tracking was surprisingly accurate and held calibration pretty easily, to my surprise. I had expected many more hiccups along the way, but was quite pleasantly surprised not to run into nothing I couldn’t easily troubleshoot myself. What I am looking forward is to keep challenging myself and to keep exploring various modes of interactions.

CraigFahner-FaceOSC

For the FaceOSC project, I decided to focus one one gesture in particular: blinking eyes. I was thinking about Walter Murch’s book “In The Blink of an Eye”. Murch was a film editor. He argues that the blink of an eye is a means for our minds to delineate experience, to punctuate our perception. The job of a film editor is, too, to delineate experience, and it’s no surprise that film audiences have been observed to blink in tandem, synchronizing with the editor’s cuts. I thought it would be interesting to force my perception of experience on a viewer by projecting my blink into the space around me. I used FaceOSC, Max/MSP and Arduino to wire the lights in my studio up to turn off each time I blink. The effect is that the entire space goes dark whenever I blink. While this is barely perceptible to me, the viewer gets to experience the same delineations of time that I do. Perhaps blinks are like sneezes – maybe they are contagious.
