Abstract

Data is pivotal to open government initiatives, where citizens are often expected to be informed and actively participate. Yet, it can be difficult for people to understand the meaning of data. Presenting data to the public in an appropriate way may also increase citizen's willingness to participate in data collection. Here we present a study which explores how large screens can support socially relevant data exploration. In a between subject laboratory experiment, we analysed how pairs of participants explored data visualisations on a high-resolution display (LHRD) and a tablet. Our results indicate that LHRDs are less cognitively demanding, while tablets offer more shared control of the interface. Data exploration had limited effect on increasing comfort with sharing personal data but helped increase perceptions of trustworthiness within the data collection process. We observed that appropriately visualised data on either platform has significant potential to increase the public's understanding of large data sets.
