Decreasing our demand for energy is an important component of the global effort to reduce carbon emissions. Energy consumption, both at home and in the workplace, is greatly influenced by human behaviour. Our research investigates how technological interventions could support behaviour-based energy reduction. This paper reports a Living Lab study on the co-design of a device for improving energy efficiency via behaviour change in a large public-sector organisation. We emphasise the importance of taking a broad view of organisational behaviour, highlighting the complex and indirect ways that it influences energy use. Methods and findings are reported from a series of insight and innovation workshops that we held with staff, and which led to the development of a prototype device-LILEE: The Little Interface for Lab Equipment Efficiency. We describe LILEE and discuss how it embodies wider lessons for the design of effective energy-related behaviour change interventions. CCS Concepts: • Human-centered computing → Participatory design; Collaborative and social computing design and evaluation methods; Collaborative and social computing devices;
Smart contract systems could change the nature of last-mile delivery for the better through enhanced precision, coordination and accountability. However, technological complexity poses a challenge for end-users participating in the design process, making it hard to explore their experiences and incorporate their perspectives. We describe a case study where technological prototypes create smart contract experiences for professional couriers and receptionists, allowing them to speculate about emerging possibilities, whilst remaining grounded in their current practices. Participants enacted a series of deliveries, choreographed by smart contracts, and their responses were explored in post-experience, one-to-one interviews. Working with professionals to explore the potential impact of smart contract technologies, revealed the systemic webs of value underlying their existing work practices. This has implications for design of such technologies, in which increased automation, efciency and accountability must be delicately balanced with the benefts of sustaining personal values, relationships and agency. CCS CONCEPTS• Human-centered computing → Ubiquitous and mobile computing systems and tools; Empirical studies in HCI; • Applied computing → Transportation.
This paper presents GeoPact, an assembly of technological objects that materialises location-aware smart contracts using internet of things and digital ledger technologies. Such contracts may facilitate the creation of distributed systems and services for transport and logistics that are locally constructed and adaptable, thus supporting specific community needs and sustainable objectives. However the technological infrastructures that underpin these systems are complex, making it difficult to engage publics in design processes. GeoPact grounds infrastructure in relatable physical activities, that are linked with holistic views of the system, and creates new experiences for public engagement. In these activities participants were invited to roleplay as couriers, and to progress through delivery scenarios which were governed by smart contracts. Participants and spectators were then encouraged to discuss their reactions, concerns and ideas. This paper illustrates the GeoPact assembly and reflects on our engagement activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
