Google has started offering Google Glass for $1500 in the U.S. to anyone interested to explore the new gadget, although it is still in beta. Google said it "decided to move to a more open beta," and said anyone in the United States could buy the Internet-connected Glass eyewear as long as stocks lasted.

Google opened sales for the gadget to the U.S. public for $1,500 last month for one day to make it available to more than just the select group of users such as apps developers.

Google said it is still working to improve hardware and software of the product, did not say whether it will make more of these glasses after they run out of stock.

The consumer version is expected to go on sale to the general public toward the end of 2014.

Google glass is actually a astamp-sized electronic screen mounted on the side of a pair of eyeglass frames. Wearers can record video, access email, provide turn-by-turn driving directions and retrieve information from the Web by connecting wirelessly to a user's cell phone. The headset is operated by head movements, voice commands and via a touch-sensitive panel that runs along one side of the device.
