This thesis is about building interactive graphical user interfaces in a compositional manner. Graphical user interface applications hold out the promise of providing users with an interactive, graphical medium by which they can carry out tasks more eeectively and conveniently. The application aids the user to solve some task. Conceptually, the user is in charge of the graphical medium, control...

In smart environments interactive assistants can support the user’s daily life by being ubiquitously available through any interaction device that is connected to the network. Focusing on graphical interaction, user interfaces are required to be flexible enough to be adapted to the actual context of the user. In this paper we describe an approach, which enables flexible user interface layout ad...

This paper presents a method of working holistically with the design of a graphical interface by studying the physical environment and the social interaction that takes place within it. After an introduction that describes the case project and approach, a conceptual model that has been applied during the project is presented. It is shown how this framework assisted the designers throughout the ...

Currently, it is difficult for a designer to create user interfaces that are of high aesthetic quality for a continuously growing range of devices with varied screen sizes. Most existing approaches use abstractions that only support form based user interfaces. These user interfaces may be usable but are of low aesthetic quality. In this paper, we present a technique to design adaptive graphical...

A Model for the Specification of Abstract User Interfaces based on Conceptual Patterns is proposed to enhance the semantic captured by an object-oriented analysis method. The model gathers both Presentation an Navigation issues. A graphical notation is also provided to make easier the specification tasks. This simple graphical notation allows that a non analyst can understand and participate in...

We studied the usability of a Voice User Interface (VUI) that is consistent with a Graphical User Interface (GUI), and focused on its dependency with user age-groups. Usability tests were iteratively conducted on 245 Japanese subjects with age-groups from 20s to 60s using a prototype of an in-vehicle information application. Next we calculated and analyzed statistics of the usability tests. We ...

The evaluation of Graphical User Interface has significant role to improve its quality. Very few metrics exists for the evaluation of Graphical User Interface. The purpose of metrics is to obtain better measurements in terms of risk management, reliability forecast, project scheduling, and cost repression. In this paper structural complexity metrics is proposed for the evaluation of Graphical U...
