This paper describes a new approach to specifying graphical layouts of arbitrary objects, which is based on a TEXlike notation. Our simplest scheme offers specifications similar to TEX’s box-and-glue metaphor. Size and position of boxes and glue can be specified by constraints. Advantages of this TEX-like formalism are its expressiveness, user-predictable layouts, and efficient implementation s...

Mixed Reality (MR) and especially Augmented Reality (AR) technologies provide high potentials for future applications. However, a lack of concepts and tools for a structured design of AR systems can be noticed. Our approach to address this problem is a visual language for the abstract specification of AR applications, called SSIML/AR. We plan to extend this language to enable the description of...

In the field of HCI there exist many formalisms for analysing, describing and evaluating interactive systems. However, in developing and evaluating user interfaces to databases, we found it necessary to be able to describe presentation and interaction aspects that are catered for poorly or not at all in current formalisms. This paper presents a framework for the systematic description of data m...

This paper reports on the work that has been done by the teams above within the EvalWeb project. The work presented here describes how ergonomic rules, that are valid for the design of graphical user interfaces, should be refined and extended in order to be suitable for the ergonomic design and evaluation of web sites. To this end a distinction is made between web user interfaces and classical ...

Automatically Generating Personalized User Interfaces Krzysztof Z. Gajos Chair of the Supervisory Committee: Professor Daniel S. Weld Computer Science and Engineering User Interfaces for today’s software are usually created in a one-size-fits-all manner, making implicit assumptions about the needs, abilities, and preferences of the “average user” and the characteristics of the “average device.”...

With the advent of software agents and assistants, the concept of so called conversational user interfaces evolved, incorporating natural language interaction, dialogue management, and anthropomorphic representations. Today's challenge is to build a suitable visualization architecture for anthropomorphic conversational user interfaces, and to design believable and appropriate face-to-face inter...

Virtual Environment interfaces are designed by implementing an interaction metaphor and comparing it to existing implementations. This technique has proven effective in desktop interfaces but the difficulty of working inside a VE remains because VE interfaces do not understand what the user is trying to do, only what the metaphor wants to do. To handle this problem, we investigated a lower-leve...

The increasing availability of various types of interactive platforms has raised the need for design environments able to support development of user interfaces that exploit interaction modalities other than the traditional graphical interfaces. In this paper we present a model-based solution to help designers in the development of voice applications. In particular, we focus on how to derive a ...

EiffelVision 2 is an object-oriented library for developing graphical user interfaces in Eiffel. It offers several strategies to organise widgets in windows, and each strategy has its own specific language and features. The goal of this master thesis is to design and implement a more abstract language to develop user interfaces that is based on the mathematical model of linear programming. The ...

We introduce the notion of function composition, an interaction technique employed in several graphical user interfaces (GUIs), for use in physical chaining applications. Allowing the user to perform function composition in systems utilizing tangible user interfaces (TUIs) for input allows for more efficient use of the interactive workspace and the physical icons. In addition, it allows the use...
