Oculus isn't taking its foot off the gas when it comes to virtual reality (VR) innovations. The Facebook-owned company recently launched the standalone Oculus Go headset, and it appears to be gearing up for its next big product, Oculus Quest, to release early in 2019.

Oculus Quest looks to bring the experience of PC-quality virtual reality to an untethered headset using six degrees of freedom tracking with four ultra-wide sensors located on the headset itself.
