本文提出了一个以用户为中心的设计过程的案例研究，以供家庭使用的能源服务。这个案例研究是用来探讨用户参与设计过程的本质。设计的目的是为基于it的服务创建一个原型，方便家庭了解他们的用电量，并暗中减少用电量。通过在整个设计过程中应用人机交互（HCI）的方法，我们设计了EnergyCoach的数字原型。EnergyCoach的最终原型是用来可视化家庭用电量，并指导家庭成员了解和减少自己的用电量。这项服务是通过一个基于网络的平台和一个移动电话平台的组合来调解的。EnergyCoach在其预期的环境中进行了测试和评估。对六个家庭进行了定性访谈，这些家庭在他们的家庭环境中测试了该服务六个月。结果显示，尽管EnergyCoach的设计受到赞赏，服务本身也被认为是有用的，但被调查者使用EnergyCoach的频率各不相同。讨论了原因，并与设计过程的早期和后期阶段的方法相关。
The article presents a case study of a user-centred design process of an energy service to be used by households. This case study is used to explore the nature of participation of users in the design process. The purpose of the design was to create a prototype for an IT-based service to facilitate for households to learn about their electricity consumption and implicitly to reduce it. By applying methods from human–computer interaction (HCI) throughout the design process, we designed the digital prototype EnergyCoach. The final prototype of EnergyCoach is structured to visualise electricity consumption in households and to coach members of the household in learning about, and reducing their own consumption. The service is mediated through a combination of a web-based platform and one for the mobile phone. EnergyCoach was tested and evaluated in its intended context. Qualitative interviews were carried out with six households who tested the service for six months in their home environment. Results reveal that although the design of EnergyCoach was appreciated and the service as such considered useful, informants varied in how frequently they used it. Reasons to this are discussed and related to methods for early and later phases of the design process.
