Google I/O is set to come with a bunch of announcements, but the first one is that Google has been working hard on augmented reality. So hard, in fact, that it's bringing AR images to Google Search. Google has promised that you will be able to view 3D models within the search engine's Knowledge box, with the option to slap one in their real living space. That way you can get a better idea of what you're looking at - whether you're more interested in this for academic reasons or to see how a new pair of shows looks compared to the rest of your wardrobe. Plus other stuff, presumably. Google was the one that brought shoes into it.
I'll be interested when it involves Lego, or a new TV, without having to download a separate app.
