By the end of the year, Google notes that a total of 11 devices will be available by the end of this year.

Meanwhile, Google said consumers should expect the Asus Zenfone AR, a second-generation phone that uses Google's Project Tango technology, to go on sale this summer.

What do you think of Google's VR efforts? Google has also partnered with HTC and Lenovo for the same.

Positional tracking has always been a feature of high-end PC headsets like the Rift and Vive, but bringing the tech to mobile VR headsets in a practical way has been remained challenging. Secondly, it will come with the promise of a better experience. The company stated that the device was created to be comfortable and simple to use, implying it's working on a relatively lightweight headset that may be somewhat portable. Ousterhout Design Group (ODG) was the first company to reveal a product based on the Snapdragon 835 VR SoC. You simply slip one of the standalone headsets on, and it works. This new device in the Vive family is a standalone unit that does not require a PC or a smartphone to power the experience and is completely wireless. Designed for low-powered phones, this streamlined version of Android will have a the Google Play Store that will feature optimized apps for these devices. Other VR headsets, like the Oculus Rift, must be connected to a PC with cables in order to operate.

Google's annual Google I/O developer conference kicks off this week and ahead of the event whispers have emerged that the firm plans to unwrap a standalone VR headset. "The idea is that you have everything you need built into the headset itself". It's also similar to Microsoft's Mixed Reality Headset development kits with inside-out tracking.

Neither headset has been shown, although HTC has released a tease of its model, pictured above.
