Verizon's Boarding Pass
Boarding Pass is a novel retail experience that helps customers shop for phones and data plans. It makes shopping for invisible things like data a tangible and fun experience by giving the customer something to hold and walk around with.
As customers wander around the store, cameras track the card they are interested in and phones react visually according to how close they are and which direction they are approaching from. And when they get close enough to a particular phone, it lights up with pertinent information. I built the computer vision side of this project using C++, Cinder, and OpenCV.
