Title: Demand Around the Clock: Time Use and Data Demand of Mobile Devices in Everyday Life
Abstract: Motivated by mobile devices’ growing demand for connectivity, and concern with the energy intensity and sustainability of networked services, in this talk I reveal the impact of smartphone and tablet apps, in terms of network demand and time use. Using a detailed mixed methods study with eight participants, I first provide an account of how data demand has meaning and utility in participants’ social practices, and the timing and relative impacts of these. I then assess the scale of this demand by drawing comparison to a more representative dataset from 398 devices in the UK and Ireland. Results highlight the significant categories of data-demanding practices, and the identification of where changes in app time- and duration-of-use might reduce or shift demand to reduce the environmental impact of online services.
Bio: Dr. Mike Hazas is a Senior Lecturer at Lancaster University, who works at the confluence of human-computer interaction and social science. His research combines qualitative and quantitative methods to understand everyday practices and technologies, how they can be related to carbon emissions and energy demand, and more sustainable trajectories. Mike co-directs the multidisciplinary Socio-Digital Sustainability group at Lancaster, and has served as a chair of the Specific Application Areas subcommittee for CHI 2015-2017. Mike is an investigator in the DEMAND Centre (EPSRC, 2013-2018) which is concerned with the relationship of social practices and energy demand.
