This paper provides an overview of a full-day workshop that was held on October 23 2004 in connection with the Third Nordic Conference on Human Computer Interaction (Nordichi 2004). The proceedings from the workshop are available from http://www.cs.aau.dk/~jans/events.html. The ideas and theme of the workshop are motivated and an outline of the contents of the papers that were presented in the ...

As the threat of terrorism becomes more prevalent, the need for technological innovations for tighter security rises. Some of the areas where security needs to be increased are at border customs stations, airports, federal buildings, embassies, sporting events, and the like where checkpoints are being set up to inspect vehicles coming onto the premises. The proposed vehicle inspection system us...

the brain – computer interface (bci) provides a communicational channel between human and machine. most of these systems are based on brain activities. brain computer-interfacing is a methodology that provides a way for communication with the outside environment using the brain thoughts. the success of this methodology depends on the selection of methods to process the brain signals in each pha...

Tangible User Interfaces (TUIs) allow interaction with computer applications using physical objects called tangibles. TUIs have a number of latent advantages over traditional user interfaces including spatial naturalness and immediate haptic feedback where users receive both tactile and digital responses from computer systems. This paper presents the preliminary design and test results of a tab...

Modern window-based user interfaces are actually a special kind of reactive system, and Petri nets may be fruitfully used to design such user computer dialogues. This paper describes a software engineering tool aimed at supporting the use of high-level Petri nets for the specification, design and implementation of user interfaces in an event-driven interface system. We assess the rationale for ...

Thinking tools are typically designed for students working on their own computers. When used from the front of a classroom, the complex graphical user interfaces of these tools can interfere with an instructor's ability to lecture effectively and to use natural gestures. A thinking tool for the grade 9 mathematics topic of "relationships" has been developed with a more gesture-friendly interfac...

The incorporation of video into our computing environment will change the way we interact with computers as much as the shift from alphanumeric terminals to graphical user interfaces. To realize this vision, video must become as accessible in our computing environment as text and images are today. Because video has different semantic, storage, and timing requirements, the realization of truly p...

Low frequency electric fields provide a means to build contact and non-contact user interfaces that are unobtrusive, responsive, inexpensive, and simple to configure. In this paper, we outline the theory and implementation of such sensing techniques, contrasting them with more familiar alternatives. We then present a range of applications that we have developed for interacting with computer gra...

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...
