Google Cardboard was created to allow anyone in the world to have a great first VR experience, using nothing more than the phone in their pocket, an extremely inexpensive viewer, and some clever software. The challenge, as we've learned since launching Cardboard in 2014, is that "everyone" includes an awful lot of people, and not all of them own the latest and greatest phone. This talk discusses the techniques that we've developed to deliver compelling VR experiences across a wide range of mobile hardware, including single-pass distortion correction, real time 360 video compositing, drift correction, and believable binaural audio while giving attendees specific instructions on how they can apply them to their own Unity VR projects.
