Complete these steps before lab on Wednesday 2/17 to setup the reacTIVision environment. You will need a webcam for the object tracking to work.

1. If you haven't downloaded and set up processing yet, do so by following step 1 and 2 from the ArduinoLabSetup.

2. Go to http://reactivision.sourceforge.net/ and download

          - the reacTIVision vision engine for your operating system

          - the reacTIVision TUIO client for Processing.

The website also contains a simulator that you can download if you like, but we won't be using it in the lab.

3. Unzip the reacTIVision vision engine, and run reacTIVision.exe to try it out. You should see a black and white pixly representation of whatever your webcam is pointed to.

4. On your computer, locate the libraries folder in your Processing directory. If you are on a Mac it's called your sketchbook library, and you can find the path to it by choosing the processing/preferences menu item from within Processing. If there already exists a folder named "tuio", rename it to "tuio_old".

5. Still in the libraries folder, create a new folder and name it TUIO.

6. Unzip TUIO_processing-1.4 and copy all four folders (examples, library, reference, src) into your new TUIO folder.

7. You can open one of the examples in TUIO/examples/TUIODemo or TUIO/examples/TUIODump and try running it. They won't do anything without graphics for them to track but you should at least be able to load them without errors if you have successfully set it up.
