Can this be used for eye tracking?

The description says that it can be used for head tracking with a dot. It doesn't say that it can be used for eye tracking in the description. I don't see another product in he accessiblity accessories that could be used for eye tracking. My son doesn't have enough control of his head to be able use it that way.
