Abstract: Indoor localization is the basis for many Location Based Services.

So far its availability is still sporadic. The industry state-of-the-art,

Google Indoor Maps, covers about 10,000 locations world wide, which is

only a small fraction of buildings such as shopping malls, train stations,

airports, museums, stadiums on the Earth. Two fundamental obstacles exist:

1) mainstream indoor localization technologies rely on RF signatures that

require extensive human efforts to measure and periodically re-calibrate;

2) service providers do not have floor plan data and have to go

through effort intensive business negotiations to obtain them from various

sources. This talk presents two projects targeting the two problems. In

Sextant, we leverage environmental physical features that are stable over

time thus eliminating the periodic calibration efforts. Users measure their

relative locations to these features with smartphones to obtain their

location. In Jigsaw, we gather image and inertial data from smartphone users

, combine vision and mobile techniques to construct the floor plans with

reasonable accuracy. Together they hold the promise to ubiquitous coverage

of indoor localization service for the whole planet.
