Nice video series about how eye tracking can be used to play games using mouse emulation. We actually showed a part of your Spore video on our sprint demo last week. Good that you show both in which games it works well, but also the cases when it does not work at all.
While mouse emulation techniques works quite well for some games, our long-term goal is of course that the game developers add native support for eye tracking input, or allow API:s or plugins for this. I found a blog post by another eye tracking company that illustrates the differences between mouse emulation an native eye tracking support:

It seems that you @gigertron has realized that native eye tracking support is the way to go. Now we just need to get the message out to the game developers out there.
