communicate, learn, work, and function in many other aspects of our daily lives.
The rapid advancement of implementation and deployment technologies has
resulted in the creation of web applications with advanced interactivity and
functionalities. However, in order for a web application to be effective in
providing the required services for users as intended, usability considerations
forms an important aspect of its design. If the usability of a web application is not
at an appropriately high level, the web user who could be anywhere in the
world, would just become frustrated and leave the website, and this would mean
the loss of a customer. A usable web application doesn't just happen; attention
must be paid to the analysis of the requirements from a user's perspective and
user workflows, with the aim of having this information drive the appropriate ·
design decisions. Despite the importance of usability for web applications, the
design of user interfaces for web applications remains a largely ad-hoc and
technologically-oriented activity.
This thesis proposes a user-centric modelling approach for the analysis and
design of a web user interface, and aims to fill the vacuum in the support of these
two specific areas in the process of web user interface development. Interaction
dynamics, user interface composition, and user perspective are three important
elements that web user interface conceptual models need to be considered. The
proposed approach includes three linked but separate models that capture the
interface at different level of granularity, namely: Context Navigation Net,
Intracontext Flow of Interaction Net, and Intracontext Composite Structural
Model.
The main objective is to provide a suitable methodology for the high level
dynamic analysis of user interaction that in fact forms the basis of the web user
interface design. In order to capture a user-centric view of an application, we
introduce the notion of considering the web user interface as a separate concern
from the application domain. The proposed approach defines a set of models
with intuitive visual notation for the modelling of the navigation dynamics, user
interaction and structural composition for a web application. Furthermore, these
models are supported with XML representation which provides enriched
semantics, and bring in the notion of user perspective declaration. In that the
modelling approach promotes and assures usability concerns are incorporated
into the web application at an early stage of the development process.
