The Eye Tribe

Is there a progam like BKB for Macintosh, so that I could use the mouse with my eyes?

If so, I'd like to know if "clicking a mouse button" could work as "approaching the eyes to an icon in the screen".

According to some e-mails I got from the option "Contact Us", I cannot program Eye Tribe to interpret "blinking the eye" as "clicking a mouse button". Do you confirm it?

Namely, it semms that Eye Tribe was not built to interpret a blinking of the eye...

Even if this is the case, it'd do for me if I can program "approaching the eyes to an icon" as "clicking a mouse button".

All I'll do only needs the "left button" (never the other one/two).

Thanks in advance.
