Call for Papers
6th MASS Workshop
Mobile Apps and Sensors in Surveys
https://massworkshop.org  

Date
4-5 June 2025

Location
London School of Economics (LSE), London, UK

Organizing committee
Local organizers: Patrick Sturgis (London School of Economics), Oriol Bosch (Oxford University) 
Scientific committee: Bella Struminskaya (Utrecht University), Peter Lugtig (Utrecht University), Florian Keusch (University of Mannheim), and Jan Karem Höhne (DZHW, Leibniz University Hannover)

Context of the workshop
Mobile devices allow researchers to collect data through built-in sensors, such as GPS, accelerometers, and other sensors, passively collect data in-browser, and use apps in addition to self-reports. Passive mobile data collection can potentially decrease measurement errors and reduce respondent burden. Active data collection using apps, camera, microphone, and other sensors allows researchers to broaden the research questions they want to study. Incorporating new measurements to augment or replace survey questions through sensors and apps brings challenges for representativeness, survey design and implementation, and measurement. This also includes ethical and legal considerations that are yet to be understood. 
The goal of this workshop is to bring together around 40 researchers from different disciplines to discuss the current state of their work on the use of mobile apps and sensors in survey data collection. The workshop is only open to participants whose abstracts will be accepted for a paper presentation. Upon acceptance participants are expected to submit a handout (max. of 5 pages).
The workshop is free of charge for participants, but participants are expected to cover their own travel and lodging costs. 

The program, selected presentations and keynotes from five earlier MASS workshops can be found at https://massworkshop.org. 

Scope of the workshop
For the sixth MASS workshop, we invite contributions that focus, among others, on the following methodological issues when using mobile apps, sensors, and wearables in surveys:


We encourage submission of work in progress and are particularly interested in studies that use experimental designs to test strategies to collect data from mobile apps, sensors, and wearables. We are open to both empirical studies as well as descriptions of research data collection and infrastructure (e.g., front- or backend of an app) and processing of data from apps and sensors.
 
Submission process and timeline
Please submit your abstract (max. 500 words) for the workshop to massworkshop@zohomail.eu. The abstract should contain a research question, data collection procedures/the description of the app, and results (if available). If results are not available yet, the abstract should outline the type of analyses that will be presented at the workshop and whether data collection took place already. 

Participation in the workshop is only possible when an abstract is accepted for the workshop. We intend to keep the workshop limited to about 40 participants.
