I am David Holz, CTO and co-founder of Leap Motion (hand tracking for VR). AMA!
I used to work at NASA and Max Planck, and was getting a PhD in Applied Math at UNC Chapel Hill when I decided to take leave to work on solving the human interface problem in technology.
We just came out with a new product made from the ground up for Virtual Reality which we call Orion and it's a big deal for the future of human experiences.
UPDATE: Hey everyone, thanks for all the questions. I'm really excited for you all to try Orion and let us know what you think! I need to head out now, but feel free to extend the conversation at http://community.leapmotion.com or poke /u/leapmotion_alex
