VR has been developing since the 1930s but recent technological advances have enabled its widespread use. VR provides an immersive experience that transports users to new worlds and elicits strong emotions. Major companies like Facebook believe VR will become integrated into daily life for billions of people. The VR industry is growing rapidly and expected to be worth $30 billion by 2020. For VR to be compelling, it must provide high fidelity, track users' movement, make them feel present, and interact naturally with virtual environments. Both 360 video and interactive VR applications are growing in popularity for entertainment, education, and branding experiences. As headsets improve and content matures, gaming is poised to drive broad consumer adoption of VR.
