Dynamic composition of portal interface for GUISET services

The increased usage of technology requires friendly and easily understandable user interfaces. In portals design, user interface is one of the critical components. Portal is a medium that Small Medium and Macro Enterprises (SMMEs) can use to advertise, grow exposure of their business and interact with their customers and community at large. This requires the portal interface to adapt to runtime changes because of the rapid update of services. This work addressed the issue of analysis of user request in order to have a clear understanding of the request. This is achievable by taking into considering the user history, preference and profile. This is realised by the design of architectural model called Dynamic User Interface (DUI) model which analyses the user request and also aggregate different components and present them as a single unit to the user. The DUI model was prototyped using Grid-based Utility Infrastructure for SMME-enabled Technology (GUISET) user interface as a use case. Experiments were conducted to compare DUI portal and Jetspeed-2 to test usability subjects. Usability was evaluated under four experiment variations: customization, adaptation after query, user satisfaction with response and portal performance. For each experiment, data was generated and presented for analysis. The results obtained show scalability and satisfaction of users with the adapted user interface on the fly.
