Capturing and predicting human behavior using wearable sensors Julian Wolfson Associate Professor, Division of Biostatistics z.umn.edu/julianw julianw@umn.edu @DrJWolfson JSM Vancouver ::: July 29, 2018
Big questions in health behavior How do we: Characterize activity patterns associated with health outcomes? Identify optimal times to deliver behavioral interventions? Enhance the provider-patient discussion around habits and behaviors? JSM Vancouver ::: July 29, 2018
The sensor revolution Explosion in: Personal monitoring devices: Fitbit, ActivPal, etc. Sensors built into smartphones Smartphones are ubiquitous in many contexts (even, increasingly, the developing world) and frequently incorporate: GPS, Accelerometer, Gyroscope, Magnetometer, Proximity sensor, Light sensor, Barometer, Thermometer/humidity sensor JSM Vancouver ::: July 29, 2018

New methodology needed! Leveraging population-level information to make individual predictions Characterizing and clustering of longitudinal behavioral patterns Detecting behavioral changepoints Aggregating data over structured networks (e.g., roads) JSM Vancouver ::: July 29, 2018
Discussion points How do we support implementation-focused collaborations for junior methodologists? Clinical trial model? Data privacy: Can we overcome the “creepy factor”? Commercialization: Crucial activity or needless distraction? JSM Vancouver ::: July 29, 2018
