Many people assume that they need to spend a fortune to start experiencing virtual reality. There are plenty of virtual reality headsets available for smartphones though. Take PLAY for instance. It is a virtual reality device that lets you play VR games, watch moves, experience 3D photos, and more. This portable headset has a uni-body structure with a phone slot to accommodate a wide variety of smartphones. It is drop-woof and waterproof.
Once you set it up, you can rely on the gyroscope sensor in your phone to track head movement. The headset is created from silicone rubber, so it will be comfortable. More information is available on Kickstarter.
