Is that not how your vision works in real life?
That's exactly what your able to do if you have the settings right.
6DOF is not an issue for me, I prefer key presses for zoom, and don't mind that I can't rotate my head. Also, it's only $10 cheaper than the Track IR w/o the promo code in that video.
I appreciate the input. I am considering this as an alternative to Track IR. I'm looking for input from people that may own the EyeX.
EDIT: Also, from the video and from what I've read it seems to have the same capabilities as Track IR (without zoom + head rotation), I'm just looking to see if someone prefers it over Track IR.
