Facilitating interactive tool selection by adaptive prompting

In order to reduce the navigation effort for tool selections, a tool prompter is proposed which maintains a working set and offers a small number of corresponding tools which can be perceived at a glance. The presentation is continuously being adapted on the basis of an application model and a user model, The chosen approach allows for a wide range of optional user involvement into the adaptation mechanisms. A prototype of the tool prompter has been implemented.

Using computational critics to facilitate long-term collaboration in user interface design

User interface design and end-user adaptation during the use of the system should be viewed as an ongoing collaborative design process . among interface designers and end-users. Existing approaches have focused on the two activities separately and paid little attention to integration of the two by supporting their asynchronous collaboration over a long period of time throughout the evolution of the interface design. Our knowledge-based domain-oriented user interface design environments serve both as design media and as communication media among interface designers and endusers. An embedded computational critiquing mechanism not only identifies possible problematic situations in a design for user interface designers and end-users but also facilitates asynchronous communication among stakeholders. The presentation of critiquing messages often triggers designers and end-users to articulate design rationale by describing how they responded to the critiques. The recorded design rationale mediates collaboration among end-users and user interface designers during the end-user adaptation and redesign of the interface by providing background context for a design decision.

Adjusting the presentation of forms to users' behavior

This poster presents an approach to make form-based interfaces easier to use. The presentation of forms is adapted to the individual user’s behawor. Color and highlighting of items are adjusted with respect to the time of last change of the item and the usually used item value compared to the currently used value. By t.lns means complex forms can be used effectively, as the user will be able to identify relevant reformation at first glance. It is discussed what information about users’ behavior has to be represented in a user model in order to provide for adaptation.

Knowledge-based support for the user interface design process (abstract)

ISSUES AND GOALS At CHI’94, a panel was held to discuss the “best” interaction technique for user interface design support. At the end oEthe discussion, the panelists as well as the audience came tcl the conclusion that each of the proposed techniques has both strengths and weaknesses. It seems that a combined approach that combines the strengths should result in better support for the user interface designer. A challenge is to find out how to combine the different approaches to overcome the weaknesses of the individual ones.

Unterstützung des Benutzungsoberflächen-Designs durch eine Kritikkomponente

Beim Entwurf grafischer Benutzungsoberflachen mus eine uberwaltigende Menge von Informationen berucksichtigt werden. Traditionell stehen diese auf Papier als Entwurfsrichtlinien oder Styleguides zur Verfugung und sind damit nur muhsam zuganglich. Eine Kritikkomponente kann durch aktive Prasentation der in einer bestimmten Designsituation benotigten Informationen den Designer unterstutzen. Auf der Basis von Erfahrungen aus verschiedenen Projekten werden verschiedene Moglichkeiten der Informationsprasentation diskutiert.
