Smartphone sensors (e.g., GPS, camera, accelerometer), apps, and wearables (e.g., smartwatches, fitness bracelets) allow researchers to collect rich behavioral data, potentially with less measurement error and lower respondent burden than self-reports through surveys. Passive mobile data collection (e.g., location tracking, call logs, browsing history) and respondents performing additional tasks on smartphones (e.g., taking pictures, scanning receipts) can augment or replace self-reports in surveys. However, there are multiple challenges to collecting these data: participant selectivity, (non)willingness to provide sensor data or perform additional tasks, privacy concerns and ethical issues, quality and usefulness of the data, and practical issues of implementation. This course will address the challenges by reviewing state-of-the-art practices of smartphone sensors, apps, and wearables data collection, ranging from small-scale studies of hard-to-reach populations to large-scale studies to produce official statistics, and discuss design best-practices for this type of measurement. Recommendations provided will include:

 

As part of this course, participants will have the chance to work on practical issues of implementing smartphone sensors, apps, and wearables into social science research. Participants will discuss their own research study designs using new technology and have the opportunity to present the scenarios of combining survey data with data from health, accelerometery, and location sensors. The course will not discuss analysis of sensor data, nor demonstrate how to program smartphone sensor apps.

Participants will find the course useful if:

Organisational structure of the course:

The lectures will include a mix of frontal teaching, short exercises and question-based discussions of use cases. The exercises are usually group-based. Participants who are currently collecting or plan on collecting data with smartphones, apps, and wearables are encouraged to discuss their study designs in the course. All participants should bring their smartphones and laptops and any wearables (e.g., fitness bracelets, smartwatches) if available.
