OpenCV for Processing

I've tried the PEEP eye tracking library, but it seems that the code need the specified camera device Tobii, otherwise the interaction will still be controlled by the mouse. Not sure if I missed anything, if anyone knows how to make it work please drop me some feedback.

I then looked for other computer vision libraries provided on the processing website and finally decided to use OpenCV for implementing my prototype, since it provides good documentation and examples. You can download the OpenCV library and example here.

Below are screen shot for the face detection and blob detection examples.

Because these functions are not specific for eye tracking, additional works are necessary. The plan for my prototype is to have some reflective tape stick to somewhere near eyes and have LED light to lighten it, so by adjust the contrast value, it can be detect more easily. Hope this plan will work for my project.
