You may have seen this in movies — a man is wearing a helmet or a pair of glasses, after that he gets sucked into another world. This is one of the impressions of what people think about virtual reality, or simply VR.
But what is VR?
Virtual reality is a computer-generated environment that lets you experience a different reality — In other words, it is a different world created by computer that separates you from the real world, and you can see, hear, or even touch and interact with things in this world.
One of the core technology of VR is tracking. VR requires precise calculation for user’s movements and actions in order to generate the appropriate environment and not making user feeling isolated or unrealistic. So sensors — from gyroscope, cameras to eye-tracking devices — are vital to this aspect.
Another one is computer graphics. Since graphics should be synchronized to the movement of the user, it needs instance calculations and feedback, which is a challenge for the device. Besides a high-performance smartphone or computer, a cloud computing network is a better solution, and it will also be the affordable solution in the near future.
There are video cloud services ready for delivering VR experience to the audience, for the purpose of experimental art, interaction and even branding. POLYV is one of the video cloud services that has researched and developed a series of solutions for VR, including video playback and livestream, providing whole new experience to entertain and learn for the audience.
VR is getting more and more attention around the world. We believe it is the technology that changes a lot of industries in the near future.
