The proliferation of smartphones and other powerful sensor-equipped consumer devices enables a new class of Web application: community sense and response (CSR) systems, distinguished from standard Web applications by their use of community-owned commercial sensor hardware. Just as social networks connect and share human-generated content, CSR systems gather, share, and act on sensory data from users’ Internet-enabled devices. In this talk, we discuss the Caltech Community Seismic Network (CSN) as a CSR system harnessing accelerometers in smartphones and consumer electronics, including the systems and algorithmic challenges of designing, building, and evaluating a scalable network for real-time awareness of dangerous earthquakes.
Annie Liu is an engineer at Facebook working on entity classification to help grow and improve the Facebook graph. In the past life she was a PhD student at Caltech doing research in the intersection between machine learning and sensor networks.
Michael Olson is an engineer at Google working on cloud infrastructure for providing Google services externally. Michael got his PhD from Caltech working on algorithms for fusing sensor data in cloud platforms.
