As a part of our continual efforts to explore new technologies and discover what they can do for interactive advertising, we came across two exciting new mobile augmented reality platforms built upon Unity3D. The QCar SDK from Qualcomm being the only solution for Android, and String is the only solution for iOS. Both solutions have their individual strengths and weaknesses, but in the end, both prove to be excellent products. For this demo, we used the demo release version of String, and QCar v1.0.0. Our goal was to create a a multi-platform experience, note differences in workflow, and share what we came up with.
