To a consumer, knowing how much energy you use is often a question mark. We get our energy bills and more often than not, they are surprisingly high. The coming of the smart grid and more specifically smart metering provides opportunities to create a better awareness on energy use among consumers. This research presents the user-centric development of a home energy management system. The focus of the research is not specifically on the functionalities per se, rather it lies on the inclusion of the energy end-user in the development process. Throughout the development, end-user research provided valuable input for the development of the system. Large quantitative surveys were alternated with small scale in-depth qualitative research. Each step generated the input for the next step in the research process, resulting in a system with functionalities tailored to the end-users needs and wants. 相似文献

一种新的笔式交互范式的可用性评估 总被引:4,自引:0,他引:4
笔式用户界面是Post—WIMP界面的一种重要形态,具有自然、和谐的交互特性。尽管笔式用户界面广泛应用于无处不在计算环境中,但很少专门对它的可用性进行评估。针对笔式用户界面的特征,提出了一种新的笔式用户界面范式,基于此范式设计并实现了一个面向教学的笔式交互系统(PenOffice),利用此系统对范式从易学性、效率、出错率和用户满意度这几个方面进行了可用性评估,从中分析了笔式用户界面以及这种新的界面范式的优点和不足。 相似文献

Usability has become established as an important aspect of product design. This paper describes an investigation that was carried out to identify the importance of usability in product choice related to other product attributes. Interviews were initially carried out to identify possible attributes that contribute to product choice. Experiments were then undertaken using the methods of active information search, structured preference elicitation, ranking and interviews in order to find out what attributes were important to people when choosing an example product – mobile phones. It was found that usability is indeed important in product choice but perhaps not as much as users themselves believe. Other attributes that were found to be more important were features, aesthetics and cost. The process of product choice was found to be complex and it may be the case that people have come to expect usability in their products. Further research is needed to understand more fully the changing role of usability in product choice and to further improve the quality of the user–product relationship. 相似文献

This paper proposes a user interface and interactivity adaptor for PCs, Internet protocol televisions (IPTVs), and mobile devices. The adaptor accounts for the screen limitations for display of mobile devices and the remote control limitations for the interactivity of IPTVs. A framework for convergence of these client‐side devices is also proposed as a basis for a video sharing service. In‐depth verification and evaluation demonstrate the robustness of the proposed adaptor. 相似文献

AppVox is a mobile application that provides support for children with speech and language impairments in their speech therapy sessions, while also allowing autonomous training at home. The application simulates a vocalizer with an audio stimulus feature, which can be used to train and amend the pronunciation of specific words through repetition. In this paper, we aim to present the development of the application as an assistive technology option, by adding new features to the vocalizer as well as assessing it as a usable option for daily training interaction for children with speech and language impairments. In this regard, we invited 15 children with speech and language impairments and 20 with no impairments to perform training activities with the application. Likewise, we asked three speech therapists and three usability experts to interact, assess, and give their feedback. In this assessment, we include the following parameters: successful conclusion of the training tasks (effectiveness); number of errors made, as well as number and type of difficulties found (efficiency); and the acceptance and level of comfort in completing the requested tasks (satisfaction). Overall, the results showed that children conclude the training tasks successfully and helped to improve their language and speech capabilities. Therapists and children gave positive feedback to the AppVox interface. 相似文献

为了适应普适计算环境中用户、设备、使用环境和开发平台的多样性,基于模型的方法被应用于用户界面开发过程中,试图在抽象层次上描述界面,通过模型转换,使其适用于不同的平台.然而,由于目前基于模型的用户界面开发方法(model-based user interface development,简称MBUID)中所采用任务模型的局限性,致使生成的界面难以满足动态环境下用户的可用性需求.提出一种基于任务模型的用户界面开发框架,旨在建模和生成有效、高效、令用户满意的用户界面.在可用性方面,为了准确描述普适计算环境中用户任务,提出一种基于感知控制理论的任务分析方法(perceptual-control-theory-based task analysis,简称PCTBTA),将使用上下文信息引入到任务分析过程中,并且在较高的抽象层次上反映交互的内容,给可用性设计提供任务空间;在技术方面,为PCTBTA任务模型向界面模型的转换提供技术支持.最后,通过实例说明所提出方法的可行性,并通过与其他方法在可用性和性能方面的比较,表明该方法的有效性. 相似文献

Mobile devices offer much potential to support older adults (age 65+). However, older adults have been relatively slow to adopt mobile devices. Although much ongoing HCI research has examined usability problems to address this issue, little work has looked at whether existing graphical icons are harder to use for this population compared with younger adults. We conducted a qualitative exploratory study and a follow-up experimental study to determine which icon characteristics help initial icon usability for older adults. We found that our older participants did have more problems using existing mobile device icons, but that particular icon characteristics – semantically close meaning (i.e. natural, close link between depicted objects and associated function), familiar, labelled and concrete (i.e. those depicting real-world objects) – improved icon usability for them. We discuss how these findings can help icon designers to create mobile device icons that are more suited to the abilities and technology experience of older adults. 相似文献

可用性是当前评价用户界面的一个重要标准,它与用户体验相关。美感有助于营造良好的用户体验,有助于帮助用户完成任务,减轻压力,保持注意力和做出正确的决策。美观的界面更有吸引力,有助于产品的视觉识别,有助于企业创造文化价值和提升核心竞争力。设计人员有时面对着美观和功能的取舍,此时不仅应该寻找平衡更应该寻求新的更巧妙的解决方案。 相似文献

The fine‐grained access control has been proved to be a reliable tool to ensure preserving of privacy of end users. In fog computing, one of the challenges is to understand users' attitudes and behaviors toward personalized control. However, few of studies have given a clear view on users' perception of the burden of interactivity when they set complex privacy settings. To this end, we conducted a user study including a lab study with 26 participants and an evaluation with 223 participants. From the lab study, we found that participants were satisfied with improved privacy settings but did not adapt well to complex personalized interfaces. We proposed effective methods to assist users to balance between the full control and the additional interaction burden, including sorting, recommendations, and establishing profiles. After this lab study, we organized a survey evaluation additionally to explore users' current usage of privacy features. Results from the evaluation showed that the principle reason that users failed to use privacy features was that they were not appropriately aware of these features. A key conclusion is that privacy settings should not only let users take over the control of smartphones but also inform them of the knowledge on privacy practices. 相似文献

In this age of collaborative software development, the importance of usable APIs is well recognized. There already exists a rich body of literature that addresses issues ranging from how to design usable APIs to assessing qualitatively the usability of a given API. However, there does not yet exist a set of general‐purpose metrics that can be pressed into service for a more quantitative assessment of API usability. The goal of this paper is to remedy this shortcoming in the literature. Our work presents a set of formulas that examine the API method declarations from the perspective of several commonly held beliefs regarding what makes APIs difficult to use. We validate the numerical characterizations of API usability as produced by our metrics through the APIs of several software systems. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
