ISML: an interface specification meta-language

In this paper we present an abstract metaphor model situated within a model-based user interface framework. The inclusion of metaphors in graphical user interfaces is a well established, but mostly craft-based strategy to design. A substantial body of notations and tools can be found within the model-based user interface design literature, however an explicit treatment of metaphor and its mappings to other design views has yet to be addressed. We introduce the Interface Specification Meta-Language (ISML) framework and demonstrate its use in comparing the semantic and syntactic features of an interactive system. Challenges facing this research are outlined and further work proposed

Systems Engineering Model and Training Application for Desktop Environment

Provide a graphical user interface based simulator for desktop training, operations and procedure development and system reference. This simulator allows for engineers to train and further understand the dynamics of their system from their local desktops. It allows the users to train and evaluate their system at a pace and skill level based on the user's competency and from a perspective based on the user's need. The simulator will not require any special resources to execute and should generally be available for use. The interface is based on a concept of presenting the model of the system in ways that best suits the user's application or training needs. The three levels of views are Component View, the System View (overall system), and the Console View (monitor). These views are portals into a single model, so changing the model from one view or from a model manager Graphical User Interface will be reflected on all other views

A methodology for the design and evaluation of user interfaces for interactive information systems

The definition of proposed research addressing the development and validation of a methodology for the design and evaluation of user interfaces for interactive information systems is given. The major objectives of this research are: the development of a comprehensive, objective, and generalizable methodology for the design and evaluation of user interfaces for information systems; the development of equations and/or analytical models to characterize user behavior and the performance of a designed interface; the design of a prototype system for the development and administration of user interfaces; and the design and use of controlled experiments to support the research and test/validate the proposed methodology. The proposed design methodology views the user interface as a virtual machine composed of three layers: an interactive layer, a dialogue manager layer, and an application interface layer. A command language model of user system interactions is presented because of its inherent simplicity and structured approach based on interaction events. All interaction events have a common structure based on common generic elements necessary for a successful dialogue. It is shown that, using this model, various types of interfaces could be designed and implemented to accommodate various categories of users. The implementation methodology is discussed in terms of how to store and organize the information

GeoZui3D: Data Fusion for Interpreting Oceanographic Data

GeoZui3D stands for Geographic Zooming User Interface. It is a new visualization software system designed for interpreting multiple sources of 3D data. The system supports gridded terrain models, triangular meshes, curtain plots, and a number of other display objects. A novel center of workspace interaction method unifies a number of aspects of the interface. It creates a simple viewpoint control method, it helps link multiple views, and is ideal for stereoscopic viewing. GeoZui3D has a number of features to support real-time input. Through a CORBA interface external entities can influence the position and state of objects in the display. Extra windows can be attached to moving objects allowing for their position and data to be monitored. We describe the application of this system for heterogeneous data fusion, for multibeam QC and for ROV/AUV monitoring

WormBase: a multi-species resource for nematode biology and genomics

WormBase (http://www.wormbase.org/) is the central data repository for information about Caenorhabditis elegans and related nematodes. As a model organism database, WormBase extends beyond the genomic sequence, integrating experimental results with extensively annotated views of the genome. The WormBase Consortium continues to expand the biological scope and utility of WormBase with the inclusion of large-scale genomic analyses, through active data and literature curation, through new analysis and visualization tools, and through refinement of the user interface. Over the past year, the nearly complete genomic sequence and comparative analyses of the closely related species Caenorhabditis briggsae have been integrated into WormBase, including gene predictions, ortholog assignments and a new synteny viewer to display the relationships between the two species. Extensive site-wide refinement of the user interface now provides quick access to the most frequently accessed resources and a consistent browsing experience across the site. Unified single-page views now provide complete summaries of commonly accessed entries like genes. These advances continue to increase the utility of WormBase for C.elegans researchers, as well as for those researchers exploring problems in functional and comparative genomics in the context of a powerful genetic system

The crustal dynamics intelligent user interface anthology

The National Space Science Data Center (NSSDC) has initiated an Intelligent Data Management (IDM) research effort which has, as one of its components, the development of an Intelligent User Interface (IUI). The intent of the IUI is to develop a friendly and intelligent user interface service based on expert systems and natural language processing technologies. The purpose of such a service is to support the large number of potential scientific and engineering users that have need of space and land-related research and technical data, but have little or no experience in query languages or understanding of the information content or architecture of the databases of interest. This document presents the design concepts, development approach and evaluation of the performance of a prototype IUI system for the Crustal Dynamics Project Database, which was developed using a microcomputer-based expert system tool (M. 1), the natural language query processor THEMIS, and the graphics software system GSS. The IUI design is based on a multiple view representation of a database from both the user and database perspective, with intelligent processes to translate between the views

Visualizing the memory performance of parallel programs with Chiron

Bibliography: leaves 78-81.This thesis describes Chiron, visualization system which helps programmers detect memory system bottlenecks in their shared-memory parallel applications. Chiron is different from most other performance debugging tools in that it uses three-dimensional graphics techniques to display vast amounts of memory-performance data. Both code-and data-oriented information can be presented in several views. These views have been designed to help the user detect problems which cause coherence interference or replacement interference. Chiron’s interactive user-interface enables the user to manipulate the views and home in on features which indicate memory system bottlenecks. The visualized data can be augmented with more detailed numerical and correlations between the separate views can be displayed. The effectiveness of Chiron is illustrated in this thesis by means of three case studies

A Domain Specific Graphical User Interface Framework

Since the early days of software development, there has been an ongoing trend towards higher-order or higher level abstractions in programming languages, software libraries and application frameworks. Some of the arguments for software development tools with higher levels of abstraction include simpler software development, improved portability and better maintainability. Higher level abstractions can however lead to reduced performance. This thesis presents an innovative graphical user interface software solution that mixes high-level and low-level approaches to achieve acceptable performance while retaining good maintainability. The solution is an extension to a graphical application framework called JavaFX. The scope of this thesis is defined by a software development project which goal is to create a graphical user interface framework. The framework is used in the creation of customer specific user interfaces for an accompanying intralogistics system. The resulting user interfaces must be able to visualize possibly thousands of objects moving on a factory floor. The views must simultaneously support user-initiated zooming, panning, and tilting of the two-dimensional view. Meeting these requirements while maintaining acceptable performance, requires an unconventional solution and a deviation from idiomatic JavaFX. The user interface framework in question is developed using a high-level graphical user interface application framework called JavaFX. JavaFX is the most recent graphical user interface toolkit included in the official Java Development Kit. It has many reactive traits and other modern high-level properties. Overcoming performance challenges with JavaFX when producing views with thousands of animated items was the key research challenge in this research. Some attention is also given to replacing JavaFX built-in dependency injection system with Spring framework to improve JavaFX suitability to the task at hand. This thesis presents a hybrid solution that overcomes JavaFX’s performance challenges in the problem domain, while retaining as much as possible of the usefulness of the high-level features present in the JavaFX framework. The key innovation is a mechanism that enables automated rendering of sprite-bitmaps from JavaFX scene-graph nodes. The solution includes a system that draws the automatically generated bitmaps to a lower-level JavaFX component called Canvas. The solution enables layered mixing of regular JavaFX views with the custom high-performance views, including seamless resizing and event handling between the two types of views. The solution enables the developers of customer specific user interfaces to choose an appropriate graphics rendering type, such that only objects that cause performance issues, typically items which number exceeds dozens, need to use the more complex high-performance system

On the design of a multiagent user interface for Next Generation Geographic Information System

In this thesis, a multiagent user interface architecture is designed for the Next Generation Geographic Information System(NGGIS) which supports the following advanced features: multiple users, multiple views, direct manipulation, distribution, and intelligence. In this architecture, agent is a basic functional unit. Agents cooperate with each other by exchanging messages. The User is just a special agent who communicates with any other agents. The ShowCase and its cooperative agents are specialized to present the geographic objects in different views. The WorkShop and its cooperative agents provide a complete interface to allow the user to manipulate the GIS objects directly. The Monitor is specialized to enforce the semantic constrains and control the system consistency. The Interaction Expert interprets multimedia user input and generates multimedia output by driving other agents. The Selector is a cooperative agent of both WorkShop and ShowCase which allows users to select geographic objects with specific constraints

User Interface for Event Configuration

Many companies today have a security system containing of devices such as cameras and other devices with some trigger functionality built in. It’s essential to be able to control all existing triggers in a security system for it to work flawlessly. As the number of triggers increases, the security system in question becomes more complicated to configure. Therefore, making configuration from an easy to understand interface for the user is of great importance. The purpose of this thesis is to make a suggestion how to configure triggers and actions for one or multiple devices through an interface in a graphical user interface. To draw a conclusion considering this, current AVHS was tested to understand how the existing system works and how to add functionality to it. A few interview sessions were held with people familiar with Axis Video Hosting System(AVHS) to get their views of what functionality they would like to add to the system and how they would like it to work. Literature studies has been made on designing interfaces as well as a design studio workshop were held with employees in Axis. The purpose of the workshop was to get an idea of in which order they would like the flow of configuration to be and how the interface should be designed. Two interfaces were designed and created based on the interviews and the design studio. They were then tested using a number of metrics to find out if they would have the wanted result from the test users. The results from the test sessions were then analyzed and presented in the thesis. Analysis of the results showed that user interface 1 were more effective in aspect of effectiveness and time efficiency while user interface 2 showed to be more satisfactory according to the test users. Even if user interface 2 showed to be more satisfactory, the difference were not considerably big. This lead to the conclusion of that user interface 1 is the more appropriate user interface for event configuration
