Google has begun to intensify work on developing virtual reality glasses, as part of a program called "Project Air", which it hopes to start selling in 2024.
And Google Glass will include cameras to combine graphics with video streams from the real world, creating a "virtual reality experience mixed with real reality."
Developed at a facility in San Francisco, prototypes will be about the size of ski goggles, without the need to be connected to an external power source.
Google is seeking to operate the glasses with a "Google processor" chip similar to the one used in Google Pixel phones, and it will work with the Android operating system.
The company still hasn't adopted a name for Google's virtual reality glasses, but it will not be "Google Glass" after the name of the product that the company launched in 2012 but did not become popular.
