Usability is seen as an important aspect for the quality of an M-learning application. Yet very little research has been conducted in this area – particularly in South Africa. Even though the trials of M-learning projects have been witnessed in the country during the last five years, very little is known about the systems that were implemented as regards their usability. Additionally, metrics and measures used in evaluating usability have not been reported. A need exists for relevant metrics to M-learning usability. The primary objective of this work was to propose metrics and measures – for the purpose of evaluating the User-Interfacedesign usability of M-learning application. The research included a literature review of M-learning, as well as the development of metrics and measures based on the Goal Question Metric (GQM) Model. This model has helped provide a reference model and measurements for evaluating the User-InterfaceUsability. A case study was used as a research strategy. An application called Kontax was selected for evaluation by users and expert reviewers. Data-collection methods consisted of User Testing and Heuristics evaluations. Data-gathering instruments included the use of surveys and user- satisfaction questionnaires based on the proposed metrics, task scenarios and expert-reviewed questionnaires based on the proposed metrics; all these instruments were developed. It was found that, although the users thought the system was very interesting, and they wished to hear more about it in the future, the system nevertheless had usability flaws which made it difficult to use. All the users failed to register so that they could use the system; additionally, the system-error messages did not help the users recognize, and recover from an error – leaving the user to simply log out. Help was not adequate, thus making it difficult for first-time users to know what to do when they needed support. The system was also said to have a lot of information presented on its home page, which caused the user to be disoriented. The Kontax application has usability flaws which should be III attended to, in order to improve its usability. The proposed metrics proved to be very useful in evaluating the usability of the tool.

New ways of interaction between users and their computing devices has revealed that users are not only interested in sharing their data, but their user interfaces as well. This calls for an extension of the traditional notion of user interfaces, to a notion where user interfaces span over multiple devices: Distributed User Interfaces (DUIs). The purpose of this thesis is to identify challenges in developing Web based DUIs, and the result is a JavaScript library that aids the development of these types of interfaces. The development has been driven in an explorative fashion, to discover techniques that is appropriate to use, when moving ideas from existing DUI frameworks for the desktop, to the Web. Soundness of the implementation has been evaluated by measuring properties of the library source code that indicates maintainability and extensibility. The conclusion is that the library has the potential of answering the needs for future DUI development targeting the Web.
