Aesthetic Artefacts Session

NordiCHI 2002 introduces "aesthetic artefacts" as a new submission category for experiments into how artistic expression and praxis affect perspectives on interfaces, contexts and design.

The computer interface has developed from merely supporting work into a broader cultural interface competing with and even replacing the book, the gallery wall, the cinema screen, etc. Traditional functionalism fails in relation to many new applications. At the same time, traditional application areas may benefit from the inspiration from how digital forms are articulated in artistic expression. Accordingly, digital arts challenge the way we understand the computer, and the relation between form and contents at the interface.

Modelling is central to doing and learning object-oriented development. We present a new tool, Ideogramic UML, for gesture-based collaborative object-oriented modelling, which is particularly effective on pen-based input and output devices such as electronic whiteboards. Furthermore we show how the interaction principles of this tool generalize to other application domains.

This describes a prototype made to support and augment continuous learning for the employees at an Intensive Care Unit. The prototype is made from off-the-shelf products. The prototype is a mobile interface consisting of a Personal Digital Assistant (PDA) and a barcode reader. On the PDA are a number of short video-films produced by the employees (especially the nurses) at the Intensive Care Unit. The content of the video-films vary from instructions about medical equipment to films about handling of sores, reflections on "best practices" etc. Barcodes distributed in the Intensive Care environment give access to the video-films. A running prototype will be demonstrated and the conference participants will be able to try the prototype themselves. Furthermore a short video-film will give examples of nurses producing video-films, discussing the video-films, and using the PDA prototype.

A system for testing interaction design without the need for programming is described. This technique has the advantage of paper prototying allowing for rapid prototyping. In the same time it makes a prototype look real why it is possible to test the prototype as if it were a functioning piece of software.

We present SpringFlow, a digital Spring-sign, which, from February to May, changes its characteristics to indicate how far gone spring is. With the aid of our Spring-sign, you navigate through time just like you would with a calendar. Its construction resembles a hollow ball, while the appearance of it depends on the user’s interactions. By tilting it, changes in sound, light, heat and cold will be produced. Based upon prior work in ubiquitous computing, SpringFlow incorporates old techniques to create something new. This paper describes the components, interaction, implementation, conceptual approach, but most of all the aesthetics.

BeatCatch is a high-level input device for creating and exploring rhythms. The focus of this work is on the expression and aesthetics of the interaction design, the level of control of the output perceived by the user and the width of the user group, stretching from novices to professionals. The BeatCatch prototype is made as an interactive metronome, which gives audile, visual and tactile feedback.

The Iron Horse combines modern technology with childhood dreams. It’s a bike – but its sounds like a horse. By biking at different speeds, one can get it to walk, trot or gallop. Sometimes it snorts, and it greets its owner and other iron horses with a neigh.
In the project, we explored how to transfer the auditive expressions of horses into the art of cycling using computational technology, to stretch the boundaries of cycling, riding and interaction design, respectively. The technology should be an inspiration for the cyclist’s fantasy; turning the playground into a jumping track, the way to school into a race, and the cycle path into a piece of the prairie.
