A user's physical and virtual environments are becoming increasingly interwoven. Mobile
and embedded devices have become more the rule than the exception: many present-day …

Task models have been used for decades in interactive system design and there are several
mature modelling approaches with corresponding tool support. However, in our own work …

In this paper we discuss an approach for linking GUI specifications to more abstract dialogue
models and supporting an evolutionary design process. These specifications are linked to …

In this paper we discuss an approach linking GUI specifications to abstract dialog models.
Both specifications are based on task models describing behavioral features. It will be …

This paper argues for a transfer of knowledge and experience gained in task-based design
to Software Engineering. A transformation of task models into activity diagrams as part of …

Model-based design of user interfaces can be a viable alternative for other user interface
specifications especially in the case of multi-platform and even more so in the case of …

End-User Programming enables end users to create their own programs. This can be
accomplished in different ways, where one of them is by appropriation or reconfiguration of …

Within the software engineering community it is widely accepted that design patterns are
very helpful to develop well-structured software. The same kind of support is expected of HCI …

Past research in task modeling suggests the need to introduce objects when using task
models for the design of interactive applications. Objects are however rarely included in the …

This paper introduces higher-order processes as a means to describe complex human-
computer interaction systems by integrating different HCI theories. A higher-order process …
