Abstract. Interactive systems are often developed without taking security concerns into account. We investigated a combination of both HCI models and access control specifications to overcome this problem. The motivation of a combined approach is to narrow the gap between different modeling perspectives and to provide a coherent mapping of modeling concepts. The general goal is a systematic introduction and tool support of security concerns in modelbased development of interactive system. In this paper we report results of our work currently concentrating on the early design steps. The focus of this presentation is on the specification of task and role hierarchies, conflicting privileges and related tool support.

“…In the approach by van den Bergh and Coninx [BeC07] entire task expressions are translated into state charts, including high-level tasks. Bomsdorf [Bom07] defines an elaborated life cycle for tasks. The work is focused on the development of web applications and considers external events related to web technology (e.g.…”

Partial order semantics for use case and task models

Abstract. Use case models are the specification medium of choice for functional requirements, while task models are employed to capture User Interface (UI) requirements and design information. In current practice, both entities are treated independently and are often developed by different teams, which have their own philosophies and lifecycles. This lack of integration is problematic and often results in inconsistent functional and UI design specifications causing duplication of effort while increasing the maintenance overhead. To address these shortcomings, we propose a formal semantic framework for the integrated development of use case and task models. The semantic mapping is defined in a two step manner from a particular use case or task model notation to the common semantic domain of sets of partially ordered sets. This two-step mapping results in a semantic framework that can be more easily reused and extended. The intermediate semantic domains have been carefully chosen by taking into consideration the intrinsic characteristics of use case and task models. As a concrete example, we provide a semantics for our own DSRG use case formalism and an extended version of ConcurTaskTrees, one of the most popular task model notations. Furthermore, we use the common semantic model to formally define a set of refinement relations for use case and task models.

“…Diverse notations for task models have been introduced (GOMS, HTA, CTT, WTM (Bomsdorf, 2007;van Welie, 1998)). Even though they differ in terms of presentation, expressiveness, level of formality and granularity they all share the same following basic principle: tasks are arranged hierarchically representing the decomposition of tasks and tasks are performed to achieve a certain goal.…”

“…Another asset of this notation is its tool support: CTTE (Mori, 2002). Various extensions have been introduced: Examplarily in (Bomsdorf, 2007;Klug, 2005) an action is not seen as atomic anymore, but defined by a life cycle. This defines a task more precisely which is employed to trigger events.…”

The paper discusses the idea of using HCI-task models to support smart environments. It introduces a collaborative task modeling language CTML that allows the specification of collaboration and comprehensive dependencies in an OCL-like style. Additionally some ideas are presented that allow informing users and usability experts about the state of actors within smart environments. The paper provides the first results of a prototypical implementation.
