Adaptive infrastructure for visual computing

2011

One key issue of both Information Visualization as well as Adaptive User Interfaces is information overload. While both disciplines have already devised well performing algorithms, methods and applications, a real merging has not taken place yet. Only a few attempts bring the surplus values of both disciplines together, whereas a fine-grained investigation of visualization parameterization is not investigated. Today's systems focus either on the adaptation of visualization types or the parameterization of visualizations. This paper presents a reference Model for Adaptive Visualization Systems (MAVS) that allows the adaptation of both the visualization type and the visualization parameterization. Based on this model, a framework for the adaptive visualization of semantics data will be derived. A use case describing the interaction with an "adaptive visualization cockpit" covering different visualization metaphors concludes the paper.

In previous work, the first author argued for simple lightweight visualisations. These are surprisingly complex to produce due to the need for infrastructure to read files, etc. onCue, a desktop 'agent', aids the rapid production of such visualisations and their integration with desktop and Internet applications. Two examples are used dancing histograms for 2D tables and pieTrees for hierarchical numeric data. A major focus is the importance of architecture, both that of onCue itself and the underlying component infrastructure on which it is built -separation of concerns, mixed initiative computation and plug-and-play components lead to easily produced and easily used systems.

When information visualization is being used to support multiple users, two characteristics are important. First, multiple users with different backgrounds have individual information needs and thus require multiple views on the information. Second, to allow users to experiment with the information and the visualization, the visualization must be adaptable. This paper presents a conceptual framework which decouples the generation and presentation of information by means of an intermediate derived model, allowing users to adapt the visualization to their information needs. Additionally, we will discuss a Web-based software architecture which deploys CORBA to allow for dynamic and interactive visualizations.

The VisMap system provides for "visual manipulation" of arbitrary off-the-shelf applications, through an application's graphical user interface. VisMap's API-independent control has advantages for tasks that can benefit from direct access to the functions of the user interface. We describe the design goals and architecture of the system, and we discuss two applications, a user-controlled visual scripting program and an autonomous solitaire-playing program, which together demonstrate some of the capabilities and limitations of the approach.

issues of translating an interactive, spatially presented, visually-dense interface into an efficient, intuitive and nonintrusive nonvisual interface are numerous. Likewise, the software architecture issues of monitoring, modeling and translating unmodified graphical applications are equally complex.

In this paper we introduce novel automatic and manual processing systems for a versatile graphical user interface comprising one or more N-dimensional background elements each of which is divided into one or more arbitrarily-shaped N-dimensional partitions, wherein each partition may contain one or more user interface elements and is associated with one or more sets of rules that define rendering, positioning, element placement and other relevant attributes and behaviors, wherein said rules can be specified in such a way as to enable said N-dimensional background to assume any desired arbitrary shape and to facilitate expansion to any desired arbitrary size without distortion or loss in quality. Our systems permit the efficient generation of intuitive graphical user interfaces in a wide variety of application domains.

Several user and task modeling approaches evolved during the past years and were applied to certain problem areas showing different strengths and weaknesses. A qualitative comparison of these approaches and techniques is di&.ult since the application and experimentation environments vary. On the other hand, the integration of approved user modeling techniques with different application environments is usually difficult if not impossible. We propose a framework that, in a first step, allows the direct comparison of results of different user and task modeling approaches in graphical user interfaces. The objective is the development of appropriate adaptive help systems for new and existing applications. The system is therefore designed as a client-server architecture to support multi-user operation. The implementation can be easily adapted to different application systems. Applications can be upgraded in a well-defined way, and with a minimal amount of effort by using the approach and tools presented in this paper. A prototype-implementation is presented consisting of an interaction protocoling and managing kernel, a user evaluating module and a corresponding adaptive help system applied to sample medical and CAD experimentation environments.

New technologies for monitoring biological and visual user data can be exploited to determine the current and changing emotional user states in HCI. This paper discusses SitAdapt, a flexible software architecture for situation analytics that evaluates various visual and biological signals and synchronizes them with eye-tracking and application meta-data in order to arrive at sound decisions for runtime adaptation of the interactive system in use. The SitAdapt system accesses the tools and resource repositories of the model-and patternbased PaMGIS development framework.

Many disciplines need to visualize and interact with high resolution media collections for big data analytics and dissemination of their findings. Tiled display environments have addressed the hardware requirements for such systems and can be scaled up to fill entire rooms. On the other hand, enabling programmers from numerous disciplines to develop software that scales respectively with tiled display environments without introducing the complexities of networked computer clusters is not trivial. This paper explains the specific software requirements for such environments, explores related software products, and presents a media-centric solution which abstracts the complexities of tiled display environments away from application developers-the MediaCommons Framework.

Visual languages have been used for some time to support the development of parallel and distributed programs. However, these languages usually tend to focus exclusively on the visual (program) design structure, in terms of the components (processes) and their interconnections represented as boxes and lines, or on the visual behaviour of the components represented as data or control flows, depicting a sequence of statements. Another limitation of most current languages is that they assume that the structure of the program design is static, where the number of components and their connections is known a priori. In this paper, we put forward an alternative visual language and a support toolset, which extends the traditional visual design structure with behavioural information, and at the same time allows the representation of dynamic design structures.
