Oriented Approach

This chapter proposes an activity-oriented approach to digital television (DTV) user interface design. Our approach addresses DTV usefulness and usability issues and entails two phases. A user activity analysis is conducted in phase one, and activities and their social/cultural context are identified. DTV service functions are then conceived to support user activities and their context. DTV service usefulness can be ensured as a result. The user interface design considers both activity requirements and user requirements such as user’s related product experience, mental model, and preferences in phase two. Consequently, DTV usability is achieved. A DTV user interface concept is thus proposed. The interface design concept contains the following design features: activity-oriented user interface flow, remote control for universal access, shallow menu hierarchy, display management, adaptive information presentation, and context sensitive functions. Usability evaluation results indicate that the user interface is easy to use to all participants.

Oriented Approach

Semantic User Interfaces (SUIs), are sets of interrelated, static, domain specific documents having layout and content, whose interpretation is defined through semantic decoration. SUIs are declarative in nature. They allow program composition by the user herself at the user interface level. The operation of SUI based applications follow a service oriented approach. SUI elements referenced in user requests are automatically mapped to reusable service provider components, whose contracts are specified in domain ontologies. This assures semantic separation of user interface components from elements of the underlying application system infrastructure, which allows full separation of concerns during system development; real, application independent, reusable components; user editable applications and generic learnability. This article presents the architecture and components of a SUI framework, basic elements of SUI documents and relevant properties of domain ontologies for SUI documents. The basics of representation and operation of SUI applications are explained through a motivating example.

The Web

“Usability rules the Web!” (Nielsen, 2000). It is very easy to recommend that a Web-learning application should be usable, but it is often a difficult design objective to achieve. We believe that usability can be achieved by bringing the interface closer to the user’s way of thinking and working. It is important to design applications that are based on the mental models of users in order to achieve high usability. Designing high usability can be achieved by adopting user interface design models and an object-oriented approach. We have developed a methodology—the Web user object modelling (WUOM) method—to guide designers to develop Web learning applications that have high usability. This chapter describes the WUOM method to develop a Web application for learning circuits based on WUOM. Evaluation of the Web application shows that it has high usability.
