Sensor data offer great potential for social scientists interested in studying attitudes and behaviors. These kind of data are particularly interesting when they can be linked to and compared with other data sources. With more and more possibilities to collect additional data through smartphones (for example through smartphone apps or activity trackers) large-scale population surveys could rather easily be enriched. Participants carry their smartphone everywhere, enabling scientists to ask respondents to make pictures, or to collect GPS and accelerometer data and track for example how much participants move around and where they go. Opportunities abound.
However, there are still many unsolved and unique methodological questions and issues to collecting and using sensor data. This session invites presentations that investigate the potentials and challenges when combining survey and sensor data. We especially welcome papers that used and collected these kind of data, and address;
The power of sensor data
o Higher data quality?
o Lower respondent burden.
The pitfalls of sensor data
o Implementation issues; nonresponse, willingness, device use.
o Technical problems.
o Issues in collecting and accessing these data across the general population.
o Data storage.
Keywords: Big data; sensor data

Modern smartphones incorporate sensors for collecting data about position, orientation, motion and environment. Previous studies have demonstrated how passively collected location and motion data can be effectively used in social science research. However, there is a lack of a detailed elaboration of such data collection from the perspective of social science methodology and its integrative placement among survey data collection methods. This extends to appropriate consideration of errors arising from sensor data in the context of their integration with survey data. While error sources have been comprehensively elaborated for survey research, particularly by the Total Survey Error framework, systematic efforts to accomplish a consistent conceptualisation for complementary sensor data remain limited.
This paper contributes a critical elaboration of specific error sources in data collection using smartphone sensors to complement survey data. It focuses predominantly on technical aspects that may have important methodological implications for social science research and addresses three main research questions:
1) How can technical characteristics of smartphones and behaviour of research participants in interacting with their devices affect the quality of data relevant for social science research?
2) How can these error sources be placed into the conceptual framework of the Total Survey Error?
3) How can device paradata contribute to better understanding of potential influences of these factors on the data quality?
The elaboration applies the findings from studies in various fields onto the context of survey research and further highlights potential error sources by evaluating a prototype mobile application for integrated collection of survey and sensor data. On this basis, the paper identifies technological and behavioural factors that can affect the data collection performance, discusses the placement of potential biasing effects into the Total Survey Error framework and underlines the importance of implementing appropriate measures for better understanding and monitoring of the technical environment during the data collection.
