Welcome
The 4th Workshop on Physical Analytics (WPA '17), collocated with MobiSys 2017, is a forum 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.
