Web mashups are defined as lightweight web applications that are composed of content, functionality and presentation from diverse web sources. The majority of web users are end-users with limited or no programming experience. In order to address varying requirements of end-users to better support their business and personal activities, end-user programming has become the most common form of programming in recent years. An emerging research focuses on the design and implementation of end-user programming tools for web mashups. This paper presents design guidelines and key factors of building a successful mashup tool from the aspects of usability and human-computer interaction (HCI). Usability is analyzed from five dimensions: usefulness, ease of use, ease of learning, error tolerance and user satisfaction. Several cognitive dimensions, cross-platform UX, liveness scales, automation degree and collaboration community are considered as significant HCI factors. To achieve these success factors, a collection of techniques and methodologies are provided including Model-View-ViewModel design pattern, responsive web design, progressive enhancement process, drag-and-drop and WYSIWYG (What You See Is What You Get). This paper also introduces a practice of the mashup tool. This mashup tool provides a user-centered, rich-featured and high-interactive composition approach that enables non-programmers to create their own applications in a graphical environment. A user-oriented, within-subject design experiment was conducted to evaluate the mashup tool. The evaluation results were promising and indicated that the proposed mashup tool has a high level of usability for end-users, and has adequately integrated HCI factors into the user experience design.
