The market for wearable devices could be technology's next goldmine, and Google wants to be a big part of it. Sundar Pichai, senior vice president of Android and Chrome, says Google will soon release a free software development kit to firms making watches, fitness gadgets and other wearable devices.

The kit would enable wearable software to communicate with the Android operating system. "Google wants to standardize how those sensors send their data to Android - and that standardization in turn should allow device manufacturers to opt for Android instead of a custom OS," reports Theverge.com.

"We want to develop a set of common protocols by which they can work together," Pichai told the SXSW conference. Most of the world's smartphones run with Android. Google is hoping to do the same thing with the emerging market for wearables. But it may face stiff competition from Apple, Samsung and LG Electronics.
