This morning at Google I/O, Google went into more detail about investments made in the core technologies that enable VR and AR, and in platforms that make them accessible to more people.

Tango enables devices to track motion and understand depth and space, and it's a fundamental enabling technology for both virtual and augmented reality. WorldSense, the positional tracking technology which makes Google's new Daydream standalone VR headsets work without any external sensors, is derived from Tango.

Tango also enables smartphone AR. With it, devices can provide indoor directions and place digital objects in the space around us. You can see what furniture looks like in your bedroom before you buy it, build interactive worlds in your living room, or summon dinosaurs into your kitchen to learn more about them. And with Expeditions AR, students can have a shared experience of digital objects, like the rings of Saturn or an erupting volcano, right in the classroom.

Daydream is Google's platform for mobile VR. There are lots of Daydream-ready phones already available, with more to come this year-including Samsung's Galaxy S8 and S8+, and devices from LG, Motorola and ASUS. Standalone headsets, a new category of devices built by our partners, are also coming to Daydream later this year. They're easy to use, and the form factor enables partners to optimize things like sensors and displays for VR.

The upcoming 2.0 release for all headsets, Daydream Euphrates, has features that make VR more fun and easier to share with others. You'll be able to capture what you're seeing, as well as cast your virtual world right onto the screen in your living room. And, soon, you'll be able to watch YouTube videos in VR with other people and share the experience in the same virtual space.

Google is also working on tools and tech to help app developers.

First, with Instant Preview, developers can make changes on a computer and see them reflected on a headset in seconds, not minutes, making development much faster for VR.

Second, a new technology called Seurat - named after the great French painter - makes it possible to render high-fidelity scenes on mobile VR headsets in real time. It uses some clever tricks to help you achieve desktop-level graphics or better with a mobile GPU. Seurat enabled ILMxLAB, a branch of Lucasfilm, to bring the cinema-quality world of Rogue One to a mobile VR headset.

Finally, Google's investments in the web mean that developers can distribute their creations to anyone, regardless of device - whether it's desktops, phones, or VR and AR enabled devices. Google was an early supporter and contributor to WebVR standards. Chrome VR, which will make it possible to browse the web in virtual reality, is coming to Daydream this summer. And Google will also support AR for the web, too. The company is releasing an experimental build of Chromium with an AR API that you can try out now.
