User interface design and development for ubiquitous software applications is challenged by the presence of varying contexts. Context comprises of user'­s computing platform, the environment in which the user is interacting with the application and user characteristics which comprise of user's behavior during interaction and user preferences for interface display and interaction. We present a framework for adaptive user interface generation where adaptation occurs when context changes. This framework introduces three new concepts. First, formalization for representing context is introduced. Our design of context specification is unique since it reflects the association of context with level and nature of user interface adaptation. Secondly, user interface generation life cycle is studied and we define a context model on top of task model to introduce the contextual conditions into user interface generation process. Using the context model, user interface designer can specify contextual requirements and its effect on the user interface. Third, context aware adaptation of user interfaces is achieved by mapping context specifications to various levels of user interface generation life cycle. We designed a specification language called rule specification using which the user interface designer can specify the mapping. With the new design of context representation, context model, and rule specification, we demonstrate how changes in contexts adapts task model which in turn adapts the user interface. / Master of Science

In this work the main aspects were discussed that need to be evaluated by establishing graphical user interface. There were discussed some user interface languages and technologies such as XML, XUL, XIML, XSLT, CSS, XHTML, analyzed some used methods for automated user interface generation. On a basis of this analysis, the proper method was chosen to apply for generating of user interface using ODRES method results. On the next stadeges of the work it was designed and developed prototype of the GUI generation system. The main goals were to develop cross-platform user interface, using as mutch as possible simplyer technologies along with that securing constant design on different web browsers. Generation process operates using the GUI specification stored in the MS SQL database and converting it to XML and along with the XSLT files used as parser. After these files are opened using web browser, XML and XSLT code is processed to an XHTML code. The process of the user interface generation is flexible and alows user change GUI’s appearance on the fly adjusting it’s specification stored on the database or XSLT rooles as well. During this work were made some ot the modifications to the ODRES database: appended few more attributes, describing graphical elements characteristics and web form relations; added extra tables.
