Sketching is an important activity in software development projects and has many advantages over strict formal languages, especially in cross-functional teams with different technical background. Sketches are used to develop all kinds of diagrams, providing a different view on the application and the underlying business logic. Several tools have been developed in recent years to support sketching activities, especially in the area of UI prototype sketching. Sketches are used to quickly develop a first impression of future UIs, helping designers, engineers, and domain experts to gain a common understanding of layout and dialog flows. Unfortunately, UI sketching tools focus on a single application aspect -the UIand do not take business processes, technical data structures, and their relationships into account. We demonstrate how UI, business process, and technical diagram sketches can be interconnected in an augmented team room.

“…We use SMART Boards for the wall-sized displays [42], because such boards were already deployed successfully in similar projects [18,44]. While the usefulness of the classic Interaction Room approach has already been shown in industry projects [10,11,23], its current non-digital presentation has many clear disadvantages, as discussed above. As soon as the AugIR reaches a sufficient level of functionality, we will gradually introduce the technology in projects that currently use a non-augmented Interaction Room.…”

Automated versioning and temporal navigation for model sketches on large interactive displays

The development of complex software systems requires the collaboration and mutual understanding of stakeholders from various backgrounds, which is usually facilitated by joint design of complex graphical models. To support this collaboration, we introduce the concept of a so-called "Augmented Interaction Room" that is equipped with large interactive wall displays, each dedicated to a particular modeling perspective. These models evolve significantly over the project life-cycle as uncertainties are resolved and design decisions are made. Our focus in this paper is to help stakeholders obtain a clearer view of the models' evolution and past design rationales, without incurring significant cognitive effort for navigating a potentially very long and detailed model revision history. For this purpose, we describe mechanisms for storing the history of the continuously evolving models, and methods for temporal navigation that semi-automatically identify particularly relevant past model versions.

“…The usefulness of non-augmented Interaction Rooms, i.e. Interaction Rooms that use physical whiteboards and magnetic annotations, has already been shown in several real projects [8,10,22]. As soon as the AugIR reaches a sufficient level of maturity, we will gradually introduce the technology in these projects.…”

“…Although the usefulness of the non-augmented Interaction Room in general and the annotations in particular have already been shown in previous industry projects [8,10,22], the use of pure physical annotations has some issues and can greatly benefit from digitization and automation. We will illustrate these issues with simple examples that use the annotations introduced above: Immutable Uncertainty Security 1.…”

Supporting collaboration of heterogeneous teams in an augmented team room

It is often difficult for a team of stakeholders with heterogeneous backgrounds to maintain a common understanding of a system's structure and the challenges in its implementation. Thus, especially in complex software projects, risks and inconsistencies are easily overlooked. In this paper, we present the concept of an Augmented Interaction Room (AugIR), i.e. a physical team room whose walls are outfitted with wall-sized touchscreens that visualize different aspects of a software system in the form of various model sketches. These sketches can be annotated by the stakeholders in order to explicitly mark important elements or indicate aspects that are critical for project success. The AugIR strives to support the collaborative work of heterogeneous teams and especially targets the inclusion of non-technical stakeholders into the communication process. Therefore, the AugIR continuously monitors the stakeholders' design and modeling activities and analyzes the relationships between annotated contents to automatically uncover inconsistencies, contradictions and hidden potential project risks.
