This instructable was made as part of the CS graduate course "Tangible Interactive Computing" at the University of Maryland, College Park taught by Professor Jon Froehlich. The course focused on exploring the materiality of interactive computing and, in the words of MIT Professor Hiroshii Ishii, sought to "seamlessly couple the dual worlds of bits and atoms.

This project involved the use of Microsoft Kinect and servo motors. Although a simple idea, you are guaranteed to get some reactions! As you probably guessed from the title, the general idea behind this project was to use a Kinect to track movement, and then use output from the Kinect to make cat eyes follow people as they walk by.

Shopping List

  1. Creepy Poster (we suggest a cat poster)
  2. 2x 1 1/2" Wooden Balls
  3. Paint
  4. 2x Standard Servo TowerPro SG-5010 Motors
  5. 8xAA Batteries (battery case optional)
  6. Arduino Uno
  7. IC Breadboard
  8. Microsoft Kinect
  9. Hot Glue Gun

Step 1: Select a Poster and Cut Out Eyeholes

Go out to the store and find your favorite poster/painting. For aesthetic reasons, I recommend finding one that already has eyes printed on it. It will be easier to trace and cut out.

<p>This is information poor on execution, can anyone actually read this and reproduce the same thing? How does the Kinect interface with the Arduino? Look what I've made! Great for you! Can you tell us how exactly? </p>
<p>I think the key detail missing from the article and the photos is that there's a PC/laptop involved.</p><p>Kinect connects to a PC where the Processing program is running.</p><p>Arduino connects to that same PC via USB and waits for a sequence of coordinates/commands that it receives via the serial connection.</p>
<p>Can the kinect be programmed to detect certain animals eg a dog?</p>
<p>It cud have been done with single servo too without gears.</p>
<p>This is awesome!</p>
