Camera Walk?

I’ve posted it before I think that I always wanted a holodeck. But of course this is nothing like that. So for this project I finally got the network camera working at my place in Queens and uploading the images every 15 minutes. I shot some video from a window at ITP and put the two together.

I knew I was going to use the Kinect and initially began using the depthMap and measuring in inches and using the values there to determine distance. That didn’t work for me. I decided to use the Center of Mass or CoM command to determine the position but then depth would be another problem.

Soooo for the purposes of this project I just adjusted the position of the kinect to be overhead to simplify the position.

Adding a fornt facing camera turned out to be more challenging. For some reason, OpenNI takes over all the cameras of the computer and will only want the kinect. Solution? Add another kinect.

I’d like to expand this further with head tracking such as imitating the look around an area or even creating the illusion of depth without 3D glasses.

Graffiti in a can/ media controller

Inspired by “Picasso’s Drawing with Light” we wanted to make something similar but instead of taking pictures, we would be using live video.

While Picasso used a slow shutter speed and a quick hand with a flashlight to create the images. We used arduino and processing to create our own “graffiti can”.

Initially we wanted to only use an accelerometer to track the movement on the screen but that proved to be very challenging since there was a a lot of computational math involved in converting the acceleration of the sensor to actual X and Y points on the screen.

After consulting ITP Resident Greg Borenstein he suggested that we should just track a light pointed at the camera in processing to create the images instead of the accelerometer. This was a last minute code change which changed our approach completely. But using examples in processing, it shortened the time to buld the code.

Here we are building the code and can at the same time.

We opted for a smaller breadboard to make things lighter and compact inside.

This might have worked better in another manner, but I mounted the arduino uno and the breadboard back to back on a strip of corrugated cardboard to make things easier to dismantle and attack by just screwing them.

One slight problem, the 9V power connector was sticking out.

But eventually everything fit but cramming it all in.

We used alligator clips to be able to quickly attach and detach the board from the super bright LED if we had to make any changes.

Getting the bluetooth to work was very tricky, because in order for the bluetooth to work, the BT chip must be disconnected while uploading the code for the arduino and attaching it afterwards. The BT will not pair with the computer unless the sketch was running. It took a bit of wrangling but it eventually worked.

We became ambitious and worked on a second can.

We also started using an external USB camera to make the video resolution a bit better. But, like the BT it was a challenge to get these two to work as well.

Crunch time! Need to fit everything inside working!

ICM Seasonal Calendar

For my ICM midterms, I thought of things to make that would look cool but at the same time, represent me or at least the artistic side of me if there ever is one. I decided to make a season clock.

I come from a country where the only sesons we have is hot and rain. Not much to choose from there so it always facinated me when I travelled when we encountered different seasons. It was only when I was working when I encountered fall and winter which always seemed the most interesting in photographs.

Last year, my father and I went to Yosemite National Park, it was my first trip to the park and of course we brought along a 4×5 camera much like Ansel Adams did.

We went there almost one year exactly to date and I took inspiration from these pictures that I shot while I was there.

and this

The whole park was practically yellow and yellow leaves were falling all around us the entire time. It was beautiful. I decided to make seasonal clock after this.

Depending on the month on your computer, the season changes. For the fall, I made an approximation of yellow leaves falling. Winter is represented by snow and spring is shown in the form of cherry blossoms taken in reference from this photo.

There is a lot of potential to add to the sketch by adding Christimas lights between Thanksgiving and January, Halloween decorations for October and so on. You can see the seasons change by changing the internal clock of your computer. Note: seasons are based on the Northern Hemesphere.

Seasonal calendar

Future versions planned:

  • Holiday decorations for holidays like Christmas, independence day and so on
  • Near real time weather based on loocation
  • Photographs from my flickr collection
  • Webcam?
