In this paper, a small case study is presented to illustrate our conceptual understanding of a task-based requirements process. We argue that sub-models as known in model-based design (e.g. taskmodels, dialog models) support the reflection about an existing work situation at a conceptual level and allow a formal specification of requirements. However, it is also shown that the integration of complementary analysis approaches facilitates a richer consideration of social as well as technical aspects. An intertwined creation of models differing in their focus and in the degree of abstraction and formality supports a more effective requirements elicitation and elaboration. In addition, the paper discusses some crucial issues in task- and model-based design such as the 'myth' of generalised taskmodels, the different roles of task and dialog models, or the influence of intentions on models of current situations. We hope to contribute to a further clarification of the problem space.

this paper discusses and illustrates work in progress on the MEMO workbench for early model-based usability evaluation of interfacedesigns. Characteristic features of the workbench include (a) the prediction of errors via rules that refer to user attributes;and (b) the automatic generation of methods for performing specific tasks and for recovering from errors.

this book constitutes the refereed proceedings of the 8th international workshop on task models and diagrams for user interface design, TAMODIA 2009, held in Brussels, Belgium, in September 2009. the 12 revised full papers presented were carefully reviewed and selected from numerous submissions for inclusion in the book. the workshop features current research and gives some indication of the new directions in which task analysis theories, methods, techniques and tools are progressing. the papers are organized in topical sections on business process, design process, model driven approach, task modeling, and taskmodels and UML.

Mixed Interactive Systems (MIS) is a generic term encompassing mixed and augmented reality, augmented virtuality, and tangible interfaces systems. the work we present in this paper deals withthe design of such systems. Several models have been proposed to describe mixed interactive systems. However, these models neither integrate MIS in the global user activity, nor take into account the dynamics of mixed interactive situations. taskmodels offer an interesting approach to cover these aspects. the purpose of our work is to contribute to the design of MIS by articulating mixed interaction models and tasks models. this paper presents complementarities and common points between these models, which will be used as the basis for the rules to articulate the task and interaction models.

task modelling has been entering the development process of web applications. However, modelling web processes from a usage-centred perspective is still challenging due to the strong distinctions of traditional interactive systems and state-of-the-art web applications. this paper proposes the WebtaskModel approach, by which task model concepts are adapted for the purpose of modelling interactive web applications. the main difference to existing taskmodels is the introduction and build-time usage of a generic task lifecycle. Hereby the descriptions of exceptions and error cases of task performance (caused by, e.g., the stateless protocol or Browser interactions) are on the one hand appended to the task while, on the other hand, being clearly separated.

Since early ergonomics, notations have been created focusing on the activities, jobs and task descriptions. However, the development of a wide variety of devices led to the generation of different interfaces from the same description of the tasks. the generation of complete current interfaces needs different types of information, some of which are not represented in usual taskmodels. the goal of this paper is to present information that seems to be lacking in the taskmodels.

the development of userinterfaces is influenced by various challenges in recent years. these are foremost caused by increasing complexity of the underlying applications and the use of these applications on different devices, by different user types and in changing environments. Model-based userinterface development approaches have been shown to be suitable to face these challenges. However, creating, transforming and linking the various included models are complex tasks. Employing patterns can avoid these disadvantages and provide an advanced concept of reuse. In this paper a general framework is introduced that describes how model-based approaches can be extended with patterns. the implementation of the framework is exemplarily shown in order to derive a concrete pattern-driven model-based approach for userinterface development. A case study is used to illustrate the derived approach.

this paper describes a model-based development process for context-aware userinterfaces. the development process consists of the specification and updates of several models followed by the generation and evaluation of a prototype. A generic runtime architecture will be presented supporting distinct prototyping renderers at different abstraction levels in order to support prototyped development during the whole design cycle of the context-aware userinterface. To clarify the functioning of the architecture, a case study will be presented, demonstrating the possibilities of this prototype-driven development approach.

Many model-based approaches for userinterfacedesign start from a task model, for which the ConcurtaskTrees notation is frequently used. Despite this popularity and the importance that has been given to a close relation with UML, no relation has been established with UML state machines, which have been shown to be useful for the description of the behavior of userinterfaces. this paper proposes a semantic mapping of tasks and all temporal relations of the ConcurtaskTrees to UML state machines which forms the basis for a compact dialog modeling notation using UML state machines. the proposed approach uses a UML profile to reduce the visual complexity of the state machine.
