Developers will get their first glimpse of Google's next-generation virtual reality headset at company's I/O developer conference, sources have told Variety.
The headset is described as a stand alone mobile VR device, meaning it won't require a phone or PC to run games and experiences.
Google has reportedly been working on the headset for more than a year.
The technology has been described as cutting-edge and will likely include inside-out positional tracking.
But sources also cautioned the company may decide to give a limited preview and there's always a chance that it may scrap the unveiling altogether and focus on its existing Daydream VR platform.
A Google spokesperson declined to comment.
Google's developer conference is being held in Mountain View, California from Wednesday to Friday, with keynote events scheduled for Wednesday and Thursday.
The company used last year's Google I/O developer conference to unveil Daydream, its Android-based mobile VR platform makes use of high-end handsets to power games and experiences.
Google this week plans to show a device described by a source as the next step for these efforts but it's unclear whether the device will run on Android or make use of a separate operating system altogether.
The headset is supposed to use on-board sensors for what's been called inside-out tracking, taking away the need to install any external hardware.
The technology is seen as the next big thing for virtual reality and has the potential to drastically simplify the use of VR headsets.
Facebook has been working on its own stand alone VR headset with inside-out tracking, which it first showed off at Oculus Connect last year.
