Google VR – Virtual Reality Development Platform
Google provides developers with two virtual reality (VR) platforms: Cardboard, the world’s most popular and accessible mobile VR platform, and Daydream, a new platform for low-latency, immersive, and interactive mobile VR.
Searching for Google Cardboard on Amazon reveals a huge number of kits available to start experimenting. They literally allow you to strap your phone to your face and contain a lens to bend the screen to create the VR effect.
VR is undoubtedly going to be a huge part of the future of human-computer interaction. Google Cardboard is one of the most accessible ways to start developing VR apps.
