    Assuming there is good contrast between the mouse and the background that should be very doable. If you have more than 1 mouse running around, then you would need to do something a little more sophisticated to track multiple objects. The best way to get x and y data is to look at the centroid (middle-mass) of the object being tracked.

    You should start off by tuning the parameters using the CMUcam2 GUI, and then you could either use the CMUcam2-emulation firmware, or modify the simple-track-color example for your application.

    You could probably get away with just logging the serial port to a text file if you are doing the rest of the processing offline. If you need to have the computer directly interact with the system, then you will need to write a program for the PC that reads the serial data.
