Towards Ubiquitous Indoor Localization Coverage for the Planet
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.
Biography
Fan Ye received his Ph.D. in 2004 from the Computer Science Department of UCLA. He got his M.S. and B.E. from Tsinghua University in 1999 and 1996. After about 8 years in IBM T. J. Watson as a Research Staff Member working on multiple projects including stream processing systems, cloud and wide area messaging, mobile crowdsensing, he went back China to Peking University exploring mobile sensing systems and applications. He joined the ECE department of Stony Brook in 2014.
His Ph.D. dissertation was on wireless sensor networks. He has published over 50 peer reviewed papers that have received about 6000 citations according to Google Scholar. He has 21 granted/pending US and international patents/applications. He was the co-chair for the Mobile Computing Professional Interests Community at IBM Watson for two years. He received IBM Research Division Award, 5 Invention Achievement Plateau awards, Best Paper Award for International Conference on Parallel Computing 2008.
His current research interests include mobile sensing platforms, systems and applications, Internet-of-Things, indoor location sensing, wireless and sensor networks.
