Demystifying the technology important for obtaining trust of HomeSense participants

Nigel Gilbert at NCRM Festival 2016

Six months into the HomeSense project, Professor Nigel Gilbert outlined the “interesting ethics issues” then needing to be answered before the required data collection could responsibly get underway in participants’ homes.

As described in his presentation, ‘The Ethics of Sensors’, for the 2016 NCRM Research Methods Festival at University of Bath, the ambition of HomeSense is to enable social researchers to use digital sensors alongside self-reported methods or observations. The project is also assessing the extent to which householders might accept sensors in their homes for research, and the final output will be a set of guidelines for use in such studies.

More refined or automated applications of digital sensors in social research could, it’s hoped, lead to more effective enabling of assisted living and tele-care services, or more efficient use of energy. But before there could be any rush to implement sensors in homes, some obvious, and less obvious, questions of ethics needed to be addressed.

Recognising Activities at Home using sensors: a HomeSense fieldwork case study

HomeSense is a National Centre for Research Methods (NCRM) supported Methodological Research Project that is focused on providing better understanding of the implications of using modern digital sensors in social research.  But before the implications can be fully understood methodological issues such as finding meaning in sensor data has to be refined, which was the focus of a paper presented by Dr Jie Jiang at The International Conference on Future Networks and Distributed Systems (ICFNDS’17) in Cambridge in July this year.

The paper discussed, as a case study, data analysis of one testbed home in the early stages of the fieldwork, and dealt with finding meaning in sensor generated data and proposed methods for comparing data generated by sensors with self-reported time-use data generated by participants.

Since one of the implications of using sensors for social research is that, in due course, activities could be recognised automatically, it also proposed a method for modelling a range of activities recorded by sensors.

While the same approach was being applied in an extended version of the study with data from more households added to the mix, publication of the paper in the Proceedings of ICFNDS’17 provided an opportunity for some of its authors – Jie Jiang, Riccardo Pozza, Kristrún Gunnarsdóttir – to sit down and discuss the approach being taken  by the HomeSense project.

That extension of the study to three households was also discussed by the team and is available here for download. Using Sensors to Study Home Activities (authors’ copy, freely available for fair use) is the latest HomeSense paper and has been accepted for publication in the Journal of Sensors and Actuator Networks.
