The forthcoming Mi VR is going on more general release in China, priced at RMB 199 (~$30).
As with other such mobile VR headsets, it only works with Xiaomi’s smartphones — and is therefore tied to the company’s mobile market footprint. So don’t expect this to arrive in the US; Xiaomi will need to bring its smartphones to the market for that to be possible.
The Mi VR hardware includes a dedicated motion sensor and system-level optimizations for 16ms ultra-low latency, aimed at minimizing motion sickness (aka VR nausea). The headset also ships with the aforementioned 9-axis motion controller to support a wider range of interactions with content. VR content for the device is downloaded from Xiaomi’s app store.
