On October 11, 2017, Oculus unveiled the Oculus Go, a mobile VR headset manufactured by Xiaomi (the device was released in the Chinese market as the Xiaomi Mi VR). Unlike the Oculus Rift, the Go is a standalone headset that is not dependent on a PC for operation. Unlike VR systems such as Cardboard, Daydream, and the Oculus co-developed Samsung Gear VR (where VR software is run on a smartphone inserted into a physical enclosure, and its screen is viewed through lenses), it contains its own dedicated display and mobile computing hardware. The headset includes a 5.5-inch 1440p fast-switching LCD display, integrated speakers with spatial audio and a headphone jack for external audio, a Qualcomm Snapdragon 821 system-on-chip, and 32 or 64 GB of internal storage. It runs an Android-based operating system with access to VR software via the Oculus Home user experience and app store, including games and multimedia apps. The Go includes a handheld controller reminiscent of one designed for the Gear VR, which uses relative motion tracking. The Oculus Go does not use positional tracking.
