SurroundSense uses your phone's sensors to figure out where you are

Smartphones use GPS locating for a variety of functions but mainly they're used on the road where their accuracy - only within 10m - is basically a case of 'near enough is good enough'. But try using one indoors. They don't work! Nor can they distinguish between two adjacent environments, however different. And 10m can make a big difference inside a shopping complex or multi-roomed office block. In a research jointly sponsored by Microsoft, Nokia, Verizon and the National Science Foundation, a group of computer engineers from Duke University is working on achieving better indoor localization using a combination of sounds, lighting and accelerometer data picked up by a mobile phone. They hope it will supplement the use of GPS systems, which most users know, have their limitations.
