This paper deals with the problem of representing complex database contents to human operators and manipulating these contents in an intuitive and user definable way. This approach makes use of the graphical facilities of todays computer systems. Information presentation is achieved by displaying graphical components on a screen, where information manipulation is done via haptical interfaces (e...

Ambient interfaces go beyond the classical graphical user interface and use the whole environment of the user for the interaction between the user and the system. In this paper we describe the design and implementation of ambient interfaces to facilitate the easy and smooth cooperation and coordination among geographically dispersed team members. We report on results of user involvement in the ...

Developers often start their work by exploring a graphical user interface (GUI) of a program. They spot a textual label of interest in the GUI and try to find it in the source code, as a straightforward way of feature location. We performed a study on four Java applications, asking a simple question: Are strings displayed in the GUI of a running program present in its source code? We came to a ...

Computer and mobile device screens are increasing in size and resolution. This increase in resolution causes problems with graphical user interfaces designed for lower resolution screens, as all information gets smaller and smaller. We present two novel techniques to make graphical user interfaces on high-resolutions screens more accessible and usable. We introduce a new in-place, localized zoo...

Usability evaluation is an indispensable issue during the development of new interfaces and interaction paradigms [1]. Although a wide range of reliable usability evaluation methods exists for graphical user interfaces, mature methods are rarely available for speech-based interfaces [2]. When it comes to multimodal interfaces, no standardized approach has so far been established. In previous st...

The emerging field of haptics represents a fundamental change in human-computer interaction (HCI), and presents solutions to problems that are difficult or impossible to solve with a two-dimensional, mouse-based interface. To take advantage of the potential of haptics, however, innovative interaction techniques and programming environments are needed. This paper describes FGB (FLIGHT GHUI Build...

We present a paradigm to generate automatically graphical user interfaces from a formal description of the data model following the well-known model-view-control paradigm. This paradigm provide complete separation between data model and interface description, setting the programmer free from the low-level aspects of programming interfaces, letting him take care of higher level aspects. The inte...
