John Brieger — Face OSC

by John Brieger @ 6:49 am 24 January 2012

[vimeo=35562537 w=605&h=400]

Uses Face_OSC to do facial recognition, smiling and mouth movement to control an array of LED’s that respond in real time to facial features. Raising your eyebrows flashes the lights on the back of the collar in rapid succession, letting everyone around know if you are surprised or angry.

The dress itself is part of a fashion collaboration between myself and Alanna Fusaro. You can see our full line here.

Sorry for the rendering issues in the video.

Duncan Boehle – FaceOSC

by duncan @ 6:27 am

[youtube=http://www.youtube.com/watch?v=MIyjMMm55Xo]

 

For this project, I adapted a previously-existing game (a couple friends and I made it during a 24-hour game jam) to handle controls using FaceOSC.

The game is based around manipulating gravity in order to jump on platforms and push blocks to reach the end of each puzzle room. The character is controlled using the arrow keys, and if the player wants to change the direction of gravity, he/she must first pause the game, then select the direction with an arrow key. In order to prevent the second use of arrow keys and the delay, I use FaceOSC to detect the orientation of the player’s face in order to determine what direction they want gravity to pull.

Unfortunately, there are some puzzles that require precise timing, and rotating the head can easily lose FaceOSC’s tracking, which can only be reacquired if the face isn’t rotated. I found that during testing, it did help players to have the pause feature so they could avoid rapidly tilting their head, so in keeping with the FaceOSC theme, I pause gravity if the player raises his/her eyebrows. FaceOSC tracks eyebrows surprisingly quickly and accurately, so this gives the player much more precise control.

The game works fairly well with the face tracking, but unfortunately Flash cannot directly communicate with FaceOSC. Because Flash doesn’t accept the UDP traffic that OSC is based on, I needed to set up an intermediate server (in Java: http://benchun.net/flosc/) to receive the UDP packets from FaceOSC and send them along to Flash via TCP on an XMLSocket. This ultimately means that I would need to distribute both FaceOSC and the Java server to players, make sure their Flash networking security settings are correct, and make sure they can run the command line Java server. For the moment, it remains mostly experimental, but a project trying to achieve this mechanic with a better distribution model would be better off statically linking with OpenCV’s face detection.

Go here to play the original version of the game (without face tracking).

Sarah Keeling; FaceOSC

by sarah @ 5:04 am

For my FaceOSC project I wanted to do something that interacted with video. I thought it could be an interesting experience if while you were watching a movie, your facial reactions in response to the movie affected how it played. My version is a bit glitchy and there are some parts commented out that I would really have liked to get working. So far what I have is: the location of the “face” controls the speed and direction which the video is played back, opening the mouth draws a rectangle of color over the entire screen from a pixel from the movie file and by raising the eyebrows the movie is paused. (Unfortunately this is really hard to see on the video but it does work!) I found a really interesting piece of code on the Processing Forums that was using incoming video stream and mousePressed to ripple the video and was hoping to get this same effect by blinking the eyes, but I’m still working on getting this part running. Also, I was trying to get other clips to works such as the the famous shower scene from “Psycho”, but I’m still working on them too.

Sorry, the second link is a bit long (and crappy) but it shows the mouth variables.

Ju Young Park – FaceOSC

by ju @ 5:03 am

For this project, I have created Face Turntable using Processing and FaceOSC. In this program, processing reads face signals from FaceOSC and use them to mix sound through changing playing rates and volumes as if a user is a DJ who plays a song with turn table. For instance, a user’s mouth width and height control the speeding rates of playing sound, and a user’s eyebrow left and eyebrow right control the volume of playing sound.

For a demo, I chose a random electronic song, called La Musica Electronica. I personally do not know the DJ who made this song, and I got this song from youtube.

As a practice for this course, I have tried to reproduce the image  “13-9-65” exactly same as much as possible by utilizing Processing.

 

Nir Rachmel | FaceOSC

by nir @ 4:30 am

In the following project, we were asked to do something “cool” with FaseOSC and Processing. I designed an interaction that allows the user to use his face to search for queries on twitter.

Once the user starts, he is presented with two pairs of opposite terms and the word “myself” in the middle. The pairs of words always change and are randomly selected. But the user can always look for tweets that have the word “myself”. Moving the user’s head, moves the cursor on the screen. The further the face goes, the bigger the pointer gets.

In order to select a word (“click”), the user has to open his mouth. Then he is transferred to another screen where he sees that query result. Hope you enjoy it!

MahvishNagda-FaceOSC

by mahvish @ 3:59 am

 

 

I wanted to use FaceOsc and Processing to create something playful. So I decided to use the data I get from FaceOsc to simulate window fog. The intention was to simulate what happens when you blow on your car window on a cold day. The window fogs up when you open up your mouth (using the ratio of your mouth height to width) and the dimensions of the fogging are controlled by your distance to the camera. I then wanted to draw on the fog, so I used touchOsc’s xy-pad on my iPad. When you’re not blowing on the window, the fog and lines fade away.

A lot of the simulation of the fogging (aka randomness) is inspired from Matt Pearson’s 100 Abandoned Art project: http://abandonedart.org/ . As you open your mouth, the application draws a circle on top of the previous circle. Each circle is actually drawn as a shape with each point on the circle connected by smoothed lines. To create a more realistic effect, I randomized each x-y points around the circle. Figuring out the right parameters for the randomization and the right values took a little bit of time: making it look frosty but not too frosty. It took a little bit of time to also tweak the rate at which shapes were drawn and faded away. The biggest challenge was fading the fog away gracefully. Since layers/shapes are stacked on top of each other, when the combined opacity level for multiple of the shapes reach 255, they all merge into one. When that “255” layer fades away, the effect is of one big blob disappearing. To work around that, I first tried collecting all the shapes I had drawn and redrawing all of them at each frame. This was computationally intensive and too slow. Instead, I finally figured out that I could simulate the effect by just overlaying the shapes that I had collected during the fade, which works well enough.

EliRosen – FaceOSC

I used the FaceOSC data to animate a simple puppet of an old man. I put the puppet together in photoshop from an image I found on google images. The old man’s glasses move up and down in response to the user moving his eyebrows. The user also controls the old mans mouth. When the puppet opens its mouth it spews colorful balls towards the screen.
