Hi Marcos,
I will be more than happy to get you a copy of the software for testing.
to be more clear about what the software do I should add; it is using a eyeX or x2-30 eye-tracker to map user gaze on the Google-earth. by moving the gaze Google-earth rotating and let the target point move to center. I am working to fix a filtering problem and I let you know as soon as it is finished.
Actual meaning of developing this application was to test how can we use just gaze to control and interact with computer as natural as possible.
Btw, what is your profession?
