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.

Traditional task-elicitation techniques provide prepared structures for acquiring and representing knowledge about usertasks. As different users might perceive work tasks quite differently, normative elicitation and representation schemes do not necessarily lead to accurate support of individual users. If the individual perception of tasks should guide the development of userinterfaces personal constructs have to be taken into account. they can be elicited through repertory grids: Personal work content and task-relevant information emerge in the course of structured interviews and can be transformed to conventional representation schemes, even for execution and prototyping. In this paper we introduce an elicitation procedure based on repertory grids and its embodiment in a working user-centered and task-based design approach.

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.

the introduction of new technologies leads to a more and more complex interactive systems design. In order to describe the future interactive system, the human computer interaction (HCI) domain uses specific models and tools. In another way, the Model Driven Engineering (MDE) approach has been proposed in software engineering domain in order to provide techniques and tools for dealing withmodels in an automated way. MDE approach is based on models, meta-models, models transformation and models weaving and aims to produce productive models, i.e. models concentrated on their generative power. Considering these two domains and the already existing HCI works in MDE, the goal of this paper is to understand actual HCI design needs and to study how MDE tools can support HCI needs. As a first response, it proposes a survey of existing MDE tools in regards to HCI model management.

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.

UML has become the standard language for modelling in different areas and domains, but it is widely recognized that it lacks support for userinterfacedesign (UID). On the other hand, ConcurtaskTree (CTT) is one of the most widely used notations for task and dialogue modelling. An important achievement is the proposed notation and semantics for CTT by extending the UML metamodel, proving that task modelling in userinterfacedesign can be accomplished by a UML compliant notation. For the interface structure design was proposed that UML's CTT could be complemented with Canonical Abstract Prototypes (CAP) leading to a model-based userinterfacedesign method co-specified by the presentation (CAP) and behaviour (UML's CTT) perspectives. In this paper we propose another step in this UID method by defining a specific model compliant withthe OMG recommended Model Driven Architecture (MDA), which will be the intermediary between the design model and an implementation of the userinterface. this proposal will align the UID method withthe MDA recommendation making it possible to automatically generate interface prototypes from conceptual models.

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.

In this article, we propose the concept of meta-userinterface (meta-UI) as the set of functions (along withtheir userinterfaces) that are necessary and sufficient to control and evaluate the state of interactive ambient spaces. this set is meta-, since it serves as an umbrella beyond the domain-dependent services that support human activities in an ambient interactive space. they are userinterface-oriented since their role is to help users to control and evaluate the state of this space. We present a dimension space to classify, compare, and contrast disparate research efforts in the area of meta-UI's. We then exploit the generative power of our design space to suggest directions for future research.

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.

the current set of temporal operators is insufficient to make effective use of taskmodels as specifications for userinterfaces. Moreover, the predominant monolithic task tree structure does not scale well for sizable applications. In order to overcome these shortcomings, a small collection of practical extensions for taskmodels is proposed. In particular, we define new temporal operators (stop, non-deterministic choice, deterministic choice and instance iteration), concepts in support of modularization and a high-level task diagram notation. Finally, we introduce a new concept for expressing cooperative taskmodelsthat distinguishes between different roles as well as between actors fulfilling these roles.
