One of the great societal challenges that we face today concerns the move to more sustainable patterns of energy consumption, reflecting the need to balance both individual consumer choice and societal demands. In order for this 'energy turnaround' to take place, however, reducing residential energy consumption must go beyond using energy-efficient devices: More sustainable behaviour and lifestyles are essential parts of future 'energy aware' living. Addressing this issue from an HCI perspective, this paper presents the results of a 3-year research project dealing with the co-design and appropriation of a Home Energy Management System (HEMS) that has been rolled out in a living lab setting with seven households for a period of 18 months. Our HEMS is inspired by feedback systems in Sustainable Interaction Design and allows the monitoring of energy consumption in real-time. In contrast to existing research mainly focusing on how technology can persuade people to consume less energy ('what technology does to people'), our study focuses on the appropriation of energy feedback systems ('what people do with technology') and how newly developed practices can become a resource for future technology design. Therefore, we deliberately followed an open research design. In keeping with this approach, our study uncovers various responses, practices and obstacles of HEMS use. We show that HEMS use is characterized by a number of different features. Recognizing the distinctive patterns of technology use in the different households and the evolutionary character of that use within the households, we conclude with a discussion of these patterns in relation to existing research and their meaning for the design of future HEMSs. RESEARCH HIGHLIGHTS • We developed an own Home Energy Management System (HEMS). • We rolled out our HEMS system in a living lab setting to seven households over a period of 18 months. • Our System provides feedback through TV, PC, smartphone and tablet-based interfaces. • This allowed us to explore 'what people do with HEMS in daily life'. • We identify and discuss nine meaningful categories of appropriating HEMS. • Based on our results, we discuss potentials for the design of future HEMSs.

We present a user-centered development process for a GPS monitoring system to be used in dementia care to support care for persons with wandering behavior. The usage of GPS systems in dementia care is still very low. The article takes a socio-technical stance on development and appropriation of GPS technology in dementia care and assesses the practical and ideological issues surrounding care to understand why. The results include (1) results from qualitative user studies from which design ideas, implications, and requirements for design and redesign were developed. (2) Description of the politics, negotiations, and challenges encountered in the project at hand. These processual matters had a powerful impact on the product that was finally envisaged. The design process was taken as a whole to illuminate the way in which design outcomes are arrived at and to foster discussion about how “best practice” might possibly be achieved.

This paper derives from a study undertaken at an emergency service centre in Sweden. The studies have focused on features of work familiar to the CSCW community, including the documenting and analysing current work practices, understanding the properties of the technology in question, and perhaps most importantly how the technology functions in and through use. Our focus in this paper exemplifies these themes through the analysis of two cases. In the first, the issue in question is the way in which an emergency is identified and dealt with, it being the case that a typical problem to be dealt with by operators, and more commonly in the days of mobile telephony, is that of multiple reporting of a single case. Of particular interest here is listening-in, which is a function in the Computer Aided Dispatch (CAD) system and by contrast that of 'overhearing', which is not. The second case focus on the relevance of wall maps, given the existence of computerized maps in these centres. Based on two cases from emergency service centres, we will show that the concept of awareness needs careful unpacking if we are to understand associated design issues.
