NIST is trying to improve indoor localisation

There are no smartphone apps for indoor navigation, but new data collected by the National Institute of Standards and Technology (NIST)—and a competition to find the app developers who can make the best use of it—may help solve the problem.
A NIST-led research team spent more than 18 months collecting data from four different smartphone models to facilitate the development of indoor navigation apps. The data, which includes smartphone sensor readings, radio frequency (RF) signal strengths and GPS fixes, should help developers create better apps to assist users in finding their way inside unfamiliar buildings.
Such “indoor localization” tools could help emergency responders find victims—or each other—when seconds count. They also could assist with locating specific works of art in large museums or misplaced equipment in hospitals, factories, or warehouses.
