"Mozilla has decided the world needs a browser designed for augmented and mixed reality goggles."
Mozilla is working on Firefox Reality, a browser with an interface specifically designed for AR and VR interaction. The source code for the browser is available already, you can follow the link to Github on The Register. It is early days yet and the demo is unlikely to reflect what we will see as this project matures.
The demo shows a web interface being controlled by a virtual hand, similar to what we have seen in VR games but there is a little trickery involved as some of the transitions are unclear and there is no indication of how to type in an URL. Navigating via bookmarks and links will be easy to implement and interface with but the real hurdle for utility will be typing.
