We investigate using smartphone WiFi signals to track human queues, which are common in many business areas such as retail stores, airports, and theme parks. Real-time monitoring of such queues would enable a wealth of new applications, such as ...

In this paper, we propose and addresses the challenge of designing a light-weight high-accuracy indoor/outdoor localization system (SpyLoc) for off-the-shelf smartphones. In SpyLoc, we want to leverages both the acoustic interface (microphone/speaker) ...

In this work, we address a critical task of detecting the user behavior of driving and texting simultaneously using smartphones. We propose, design, and implement TEXIVE which achieves the goal of distinguishing drivers and passengers, and detecting ...

We present SmartLoc, a localization system to estimate the location and the traveling distance by leveraging the lower-power inertial sensors embedded in smartphones as a supplementary to GPS. To minimize the negative impact of sensor noises, SmartLoc ...

In this work, we present SilentSense, a framework to authenticate users silently and transparently by exploiting the user touch behavior biometrics and leveraging the integrated sensors to capture the micro-movement of the device caused by user's screen-...

In this presentation, Dr. Henry Tirri, EVP & CTO of Nokia and UC Berkeley will discuss insights into the social and scientific implications of the technology trends being driven by the rise of large scale multi-device cloud-based computing. The cloud ...

This keynote presentation will focus on the challenges and opportunities imposed on mobility and wireless communications technologies by the emerging and explosive needs of the future Internet of Things. As traditional (wireless) networking meets the "...
