You're standing on a street corner and remember that you need to pick up a video game for your sister's birthday. On your smartphone, you search Google and tap on the "in stock nearby" link next to the blue dots that show up for some of the search results. Google then shows you which local retailers have the game in stock.

That buying omniscience, where your mobile device can tell you whether what you want is nearby, was announced Thursday by the search giant.

The blue dots in the search results link to participating retailers, which currently include Best Buy, Sears, Williams-Sonoma, Pottery Barn, and West Elm. The "in stock nearby" link connects to the seller's page, where the retailer near you notes whether the given item is "in stock" or has "limited availability." The distance from your current location is also indicated if you have enabled My Location or manually specified your location.

Google also has forms online so other retailers can become part of the program.

The U.S.-based functionality is available for an iPhone, a Palm webOS phone, or any device using the Android mobile operating system. After going to Google.com, the user clicks on the "more" link, and then "shopping," or, alternatively, looks for "shopping results" in the search results. Mobile product search with local inventory was first shown in December by Vic Gundotra, Google's vice president of engineering.

Andrew Frank, a research director at Gartner, noted that local-inventory product search is "part of a trend" where new functionality is coming about because the technical feasibility of various pieces have come together.
