Introduction
The 3rd edition of this workshop will continue to focus on the themes and applications that motivated the successful organization of the 1st and 2nd editions of the Physical Analytics workshop at MobiSys 2014 and 2015.

The workshop is motivated by the observations that people spend a significant part of their daily lives performing a variety of activities in the physical world—travelling to places (including commuting to/from work using public or private transport), dwelling and engaging in various activities at various locations (e.g., exercising in the gym, eating at restaurants and food courts) , interacting with various physical objects and artefacts (e.g., touching or picking up products at a retail store, or browsing through books and magazines at a library), being subject to various audiovisual stimuli (e.g., listening to announcements at transit hubs, watching advertisements on public displays or movies on TV) and interacting with other people (in groups, as part of crowds or one-on-one). These activities and interactions contain a wealth of information about user behavior, preferences, attitudes and interests, that, if harnessed, can benefit both users and consumer-facing businesses.

While research has been underway in utilizing various sensing and analytics tools to capture and annotate such behavior (e.g., profile smoking episodes using wearable devices or monitor consumer reactions to advertising content via video analysis), the vast majority of such research focuses on exploring individual sensing techniques targeted at specific activities, and is scattered across various academic forums. The goal of this workshop is to offer a unified forum to explore both (a) the technologies (current and emerging) that can enable unobtrusive capture of such individual and collective physical world behavior, and (b) the real-world commercial applications and services that leverage upon such understanding of physical world behavior.
In particular, the workshop solicits submissions that relate to three distinct questions:
  • What types of technologies (e.g., use of existing or new mobile/wearable sensors, use of passive RF monitoring) can capture different facets of physical world behavior?
  • How actionable are the insights on physical behavior context that are generated via analytics over such captured data streams—in other words, what types of accuracy, false positives/negatives result from the use of various technologies, and what analytics tools can enhance these performance metrics?
  • What early examples of commercial usage of physical analytics are emerging across different vertical domains, and what bottlenecks remain to be overcome for successful utilization of such analytics-generated insights?
By bringing together researchers and practitioners from industry to have a continuing conversation on Physical Analytics, our goal is to help coalesce a research agenda for our community.
Call For Papers
The 3rd Workshop on Physical Analytics (WPA-16), collocated with MobiSys 2016, solicits submissions broadly related to technologies, experiments and practical applications that center on the capture and understanding of the physical behavior of individuals, groups, and crowds in the physical world. Activities that people perform in the physical world— e.g., travelling to places (commuting to/from work using public or private transport), dwelling and engaging in various activities at various locations (e.g., exercising in the gym, eating at restaurants and food courts), interacting with various physical objects and artefacts (e.g., touching or picking up products at a retail store, or browsing through books and magazines at a library), being subject to various audiovisual stimuli (e.g., listening to announcements at transit hubs, watching advertisements on public displays or movies on TV) and interacting with other people (in groups, as part of crowds or one-on-one)—contain a wealth of information about user behavior, preferences, attitudes and interests. Such information is increasingly being proposed for novel services and applications across diverse industries, such as healthcare, telematics and retail. This workshop focuses on exploring how various technologies and capabilities, such as multimedia sensing, localization, wearable computing, activity recognition and privacy, can be harnessed holistically to build workable or plausible solutions that can capture real-world physical behavior of users.

Topics of interest (NOT an exhaustive list):
  • Wearable & mobile computing for physical analytics
  • BLE, RFID, NFC, cameras, and other infrastructure to support physical analytics
  • Indoor localization applied to physical analytics
  • Crowdsourcing for physical analytics
  • Algorithms for analyzing physical signals, including location, video, and audio
  • Privacy requirements, primitives & APIs for physical analytics
  • Using online/social analytics to augment physical analytics
  • Systems, toolkits and data processing platforms for physical analytics
  • Domain-specific Physical analytics (e.g., retail, healthcare, transportation, insurance, etc.)
  • Emerging applications of physical analytics
  • Authentication & Trust mechanisms for physical analytics
  • Submission
    All submissions must be original work not under review at any other workshop, conference, or journal. While the workshop will accept papers describing completed work as well as work-in-progress, the emphasis is on early discussion of novel and radical ideas (potentially of a controversial nature) rather than detailed description and evaluation of incremental advances. Submissions must be no greater than 6 pages in length and must be a PDF file. Reviews will be single-blind: authors name and affiliation should be included in the submission. Submissions must follow the formatting guidelines at http://www.sigmobile.org/mobisys/2016/submission.php

    Please submit you papers through EasyChair: https://easychair.org/conferences/?conf=wpa16 .
    The deadline for submissions is April 15th, 2016 April 20th, 2016 11:59pm (AoW).

    Keynote Talk: "Tracking Mobiles, Objects, and People in the Wireless Internet of Things" by Prof. Kyle Jamieson, Princeton University.

    Abstract: Phased array signal processing has long been employed outdoors in radar, underwater in sonar, and underground in seismic monitoring. Today, it has the potential to revolutionize the Internet of Things (IoT) by giving us the ability to track every one of the billions of IoT devices indoors, and meet their exploding bandwidth requirements. But to make the shift to indoor wireless networks, it must cope with strong multipath radio reflections, packetized data transmissions, and commodity hardware platforms. In this talk I will describe two relevant systems through the lens of system-building and experimentation. First, I will describe an indoor location system that uses solely the existing Wi-Fi infrastructure to achieve a median location accuracy of 23 centimeters, and sub-second response time, allowing Wi-Fi-enabled devices to be tracked in real-time. Next, I will present a system that can order RFID-tagged books placed on a library shelf 3-5 cm from each other, detecting any misshelved books. Finally, I will conclude with ongoing work in fine-grained motion tracking.
