Hello there,
I developed a low cost eye tracking system. I just graduated from High School, and I am pursuing to study an Engineering career.
I would like you to check it out on Youtube, I am also competing in the youtube space lab competition.

Wow! That's impressive! Is the way you track eye movement by measuring electric potential your original idea?
Wow! I second the Wow!
Thank you! I'm glad you guys have liked my project.
@pekkaa: Yes, that's how I am detecting the eye movements. I am using the technology called "Electrooculography", which consists in placing some electrodes around the eyes placed on the skin.
