John Jenkins Center for Embedded Networked Sensing Open mHealth What is Par+cipatory Sensing? An approach to data collec.on and interpreta.on in which individuals, ac.ng alone or in groups, use their personal mobile devices and web services to systema.cally explore interes.ng aspects of their worlds ranging from health to culture. Real Time (always on) Real Place (always carried) Real Context (historical, spa.al, environmental, social) Real Applica2ons (civic and environmental data, transporta.on, health, educa.on) Data collec+on Automated capture Self-­‐Report Mobility GPS ACCELEROMETER Classifica+on Mobility State (i.e., s+ll, walking, running, biking, driving) SystemSens Collect phone usage, context (e.g. +me/space) and resource consump+on Informa+on recorded directly by the user Smart Reminders
