Esta dissertação apresenta um framework de desenvolvimento de uma interface gráfica de usuário para um sistema de modelagem poligonal tridimensional, a partir de critérios ergonômicos que atendam os requisitos fundamentais de usabilidade. A pesquisa foi especialmente orientada a satisfazer principalmente as necessidades individuais dos diferentes perfis de usuários que fazem uso de aplicações similares. Para isto, foram estudados conceitos pertinentes às áreas de Ergonomia, Usabilidade e Interação Humano-Computador. Isto permitiu obter estratégias que podem ser utilizadas durante o estágio de concepção de uma interface de usuário, a fim de promover e garantir a ergonomia de um sistema em estágios anteriores à sua implementação, economizando recursos e prevenindo possíveis problemas de usabilidade. Um dos aspectos fundamentais do protótipo proposto nesta dissertação é a sua adaptabilidade, onde um dos benefícios da utilização deste tipo de recurso é a capacidade de reduzir a complexidade durante o aprendizado de um sistema por usuários novatos, selecionando informações essenciais e indicando as próximas ações possíveis, já que o sistema proposto baseia-se nos resultados de passos anteriores. A técnica de avaliação desta interface gráfica utiliza uma lista de verificação (checklist) ergonômica...

In the context of an effort to develop methodologies to support the evaluation of interactive system, this paper investigates an approach to detect graphical user interface external bad smells. Our approach consists in detecting user interface external bad smells through model-based reverse engineering from source code. Models are used to define which widgets are present in the interface, when can particular graphical user interface (GUI) events occur, under which conditions, which system actions are executed, and which GUI state is generated next. From these models we obtain metrics that can later be used to identify the smells.

We present a database client software—Neurovascular Network Explorer 1.0 (NNE 1.0)—that uses MATLAB® based Graphical User Interface (GUI) for interaction with a database of 2-photon single-vessel diameter measurements from our previous publication (Tian et al., 2010). These data are of particular interest for modeling the hemodynamic response. NNE 1.0 is downloaded by the user and then runs either as a MATLAB script or as a standalone program on a Windows platform. The GUI allows browsing the database according to parameters specified by the user, simple manipulation and visualization of the retrieved records (such as averaging and peak-normalization), and export of the results. Further, we provide NNE 1.0 source code. With this source code, the user can database their own experimental results, given the appropriate data structure and naming conventions, and thus share their data in a user-friendly format with other investigators. NNE 1.0 provides an example of seamless and low-cost solution for sharing of experimental data by a regular size neuroscience laboratory and may serve as a general template, facilitating dissemination of biological results and accelerating data-driven modeling approaches.

Background: Researchers wishing to conduct genetic association analysis involving single nucleotide polymorphisms (SNPs) or haplotypes are often confronted with the lack of user-friendly graphical analysis tools, requiring sophisticated statistical and informatics expertise to perform relatively straightforward tasks. Tools, such as the SimHap package for the R statistics language, provide the necessary statistical operations to conduct sophisticated genetic analysis, but lacks a graphical user interface that allows anyone but a professional statistician to effectively utilise the tool. Results: We have developed SimHap GUI, a cross-platform integrated graphical analysis tool for conducting epidemiological, single SNP and haplotype-based association analysis. SimHap GUI features a novel workflow interface that guides the user through each logical step of the analysis process, making it accessible to both novice and advanced users. This tool provides a seamless interface to the SimHap R package, while providing enhanced functionality such as sophisticated data checking, automated data conversion, and real-time estimations of haplotype simulation progress. Conclusion: SimHap GUI provides a novel, easy-to-use, cross-platform solution for conducting a range of genetic and non-genetic association analyses. This provides a free alternative to commercial statistics packages that is specifically designed for genetic association analysis.; Kim W Carter...

Approved for public release; Distribution is unlimited; The Computer-Aided Prototyping System (CAPS) is an integrated collection of software tools that support the development of software systems utilizing the prototype paradigm. Central to CAPS is the Prototype System Description Language (PSDL). The PSDL Editor supplied in CAPS Release 1 provided a unique combination of a graphical interface for editing PSDL data flow diagrams and an attribute-grammar based text editor to enforce syntactically correct PSDL prototypes. Feedback from CAPS users highlighted on productivity impacts due to the dual user interface as well as the steep learning curve required to become proficient with the attribute- grammar based text editor. This research initiates the development of the next generation of the CAPS PSDL Editor, focusing on the graph editor. Our approach provides a single graphical user interface with pull-down menus for editing both graphical and text information. Automatic syntax generation and validation as well as limited semantic validation is provided by a background syntax/semantics checker. The result of this research is a working graph editor meeting all the new requirements. When integrated with a the new syntax/semantics checker...

Approved for public release, distribution is unlimited; This thesis investigates the use of current graphical interface techniques to build more effective computer-user interfaces to Operations Research (OR) schedule optimization models. The design is directed at the scheduling decision maker who possesses limited OR experience. The feasibility and validity of building an interface for this kind of user is demonstrated in the development of a prototype graphical user interface called TaskMaster. TaskMaster is designed as the Dialog component of a scheduling Decision Support System (DSS). The underlying scheduling model uses set-partitioning and mixed-integer linear programming to generate optimal schedules. Although the model was originally developed to address a specific problem, inter-deployment scheduling of Navy surface ships, TaskMaster has been designed to be problem-independent, enabling it to address a broad range of scheduling problems with the same general structure. TaskMaster demonstrates the type of interactive, graphical interface that can be developed specifically for non-specialists. It is easy to learn and to use, and yet fully exploits the power of a sophisticated OR scheduling model. The prototype is implemented on a NeXT computer...

Approved for public release; distribution is unlimited.; The purpose of this thesis was to design and implement a graphical user interface for a multimedia database management system prototype previously implemented at the Naval Postgraduate School. Because of the complexity of the data types and the difficulty of manipulating them, it was very hard for a casual user to use the previous system. Since graphical interaction simplifies control dialogue, the authors designed and implemented a graphical user interface using C++ and InterViews 3.0.1 for a Sun-3 workstation under a Unix X-Windows environment with mouse support. They then connected this interface to the multimedia database system prototype. Their interface supports incremental query specification using extended SQL and can be connected to database applications in several different ways. An embedded global data structure, a text file, or a character string can be used for connections. A second version of the interface for a Sun-4 workstation was built and connected to another database system using the character string and text file. This version demonstrated even better performance.

Approved for public release; distribution is unlimited.; Graphical User Interfaces (GUI) are quickly becoming the standard operating environment for most software programs and operating systems. Ease of use, rapid learning and the ability to retain complex task sequences and operations are some of the advantages attributed to this type of interface. When properly implemented the GUI can provide a natural interaction between the user and the computer. Initial acceptance and continued use of any program can be greatly enhanced by proper design of this interface. It is expected that this trend toward visual representation of a task's objects and actions will be more fully developed and expanded in future years. This thesis explored the principles of interface design with particular attention given to the specific characteristics associated with GUI design. Unique design concepts associated with Negotiation Support Systems were also considered. These design techniques and principles were then applied in the analysis and design of the graphical user interface for a Bilateral Negotiation Support System based on multiple attribute utility theory. The program was written in Microsoft Visual Basic for use under the Microsoft Windows 3.0 operating environment.; Lieutenant Commander...

Approved for public release; distribution is unlimited; This research analyzed and decomposed U. S. Space Command missions to determine the requirements of a Military Satellite Communications Decision Support System (MDSS). Alternative functional architectures for an MDSS were evaluated and a geographical user interface prototype was developed. MDSS system requirements were derived through the combined use of the method of Critical Success Factors and the Representations, Operations, Memory Aids, and Controls method. The sandwich' architecture was suggested as the most suitable functional architecture for MDSS development. The user interface prototype allowed potential MDSS users to gain an appreciation off the look and feel of a potential system so they could more precisely articulate their specific requirements to MDSS builders; http://archive.org/details/militarysatellit00henr; Major, United Stated Marine Corps

Approved for public release; distribution is unlimited; A Graphical User Interface (Gul) was developed and implemented as the front end of the NPS software Joint Army/Navy Rotorcraft Analysis and Design (JANRAD). The original JANRAD computer program was developed to aid in the analysis of helicopter rotor performance, stability and control and rotor dynamics. An interactive program, JANRAD was capable of accurately and quickly solving helicopter design problems at the preliminary design level. The addition of the Gul greatly simplified the use of the program but added considerable complexity to the original MAThAB0 M-File code. Because of the increased complexity, only the Performance Analysis module of the program was modified. The use of several new features of MAThAB0 version 5.1, such as the GUIDE0 and Structure functions, simplified the construction of the Gul environment and enhanced the tie between the user interface and performance calculation routines. Although initiated from the MAThAB command line, the program can now be worked entirely from the "Windows'1 environment. The performance routines weremodified extensively to connect the user input with the existing analysis routines. However, the fundamental method of analysis remains unchanged. Several cases of Sikorsky UH-60A Black Hawk input data were run and results compared with those from JANRAD version 3.1(1995). The results correlated exactly. A users Guide was developed and is included in Appendix A.; http://www.archive.org/details/developmentofgra00lapa; Lieutenant Commander...

A constraint satisfaction problem is a classical artificial intelligence paradigm characterized by a set of variables (each variable with an associated domain of possible values), and a set of constraints that specify relations among subsets of these variables. Solutions are assignments of values to all variables that satisfy all the constraints. Many real world problems may be modelled by means of constraints. The range of problems that can use this representation is very diverse and embraces areas like resource allocation, scheduling, timetabling or vehicle routing. Constraint programming is a form of declarative programming in the sense that instead of specifying a sequence of steps to execute, it relies on properties of the solutions to be found, which are explicitly defined by constraints. The idea of constraint programming is to solve problems by stating constraints which must be satisfied by the solutions. Constraint programming is based on specialized constraint solvers that take advantage of constraints to search for solutions. The success and popularity of complex problem solving tools can be greatly enhanced by the availability of friendly user interfaces. User interfaces cover two fundamental areas: receiving information from the user and communicating it to the system; and getting information from the system and deliver it to the user. Despite its potential impact...

Public digital displays are moving towards open display networks, resulting in a shift in the focus from single-purpose public displays that are developed with a single task or application in mind, to general- purpose displays that can run several applications, developed by different vendors. In this new paradigm, it is important to facilitate the development of interactive public display applications and provide programmers with toolkits for incorporating interaction features. An important function of such toolkits is to support interaction with public displays through a users' smartphone, allowing users to discover and interact with the public display applications configured in a given display. This paper describes our approach to providing dynamically generated graphical user interfaces for public display applications that is part of the PuReWidgets toolkit.; Jorge Cardoso has been supported by “Fundação para a Ciência e Tecnologia” (FCT) and “Programa Operacional Ciência e Inovação 2010”, co-funded by the Portuguese Government and European Union by FEDER Program and by FCT training grant SFRH/BD/47354/2008.

The research presented here aims to design a feasible and adequate mobile application (app) user interface. This mobile app is part of Us'em system, designed to promote self-rehabilitation after stroke. The system is based on wearable, mobile and tracking sensors-based technology. The app works as a feedback tool, communicating Us’em system users about the frequency of their upper limb moves and about their recovery process. The mobile app aims increasing patient’s motivation in using their arm-hand through the day and improving their rehabilitation through self-training at home with continuous feedback. The design of its user interface is of great relevance, because it determines if post stoke patients can use Us’em system. The empirical part begins with interviews, questionnaires and observation of post stroke patients and physical therapists from Portugal and the Netherlands. It provides a better understanding of post stroke rehabilitation process and stroke victims’ characteristics and requirements regarding rehabilitation and mobile devices interaction. The gathered information contributed to the development of a prototype that materializes the defined Us’em app. The prototyping process ran through iterative cycles of design...

In the past, the features of a user interface were limited by those available in the existing graphical widgets it used. Now, improvements in processor speed have fostered the emergence of interpreted languages, in which the appropriate method to render a given data object can be loaded at runtime. XML can be used to precisely describe the association of data types with their graphical handling (beans), and Java provides an especially rich environment for programming the graphics. We present a graphical user interface builder based on Java Beans and XML, in which the graphical screens are described textually (in files or a database) in terms of their screen components. Each component may be a simple text read back, or a complex plot. The programming model provides for dynamic data pertaining to a component to be forwarded synchronously or asynchronously, to the appropriate handler, which may be a built-in method, or a complex applet. This work was initially motivated by the need to move the legacy VMS display interface of the SLAC Control Program to another platform while preserving all of its existing functionality. However the model allows us a powerful and generic system for adding new kinds of graphics, such as Matlab, data sources...

Although a GUI largely replaces textual descriptions by graphical icons, the textual items are not completely removed. The textual items are inevitably used in window titles, message boxes, help items, menu items and popup items. Textual items are necessary for communicating messages that are beyond the limitation of graphical messages. However, it is necessary to harness the textual items on the graphical interface in such a way that they complement each other to produce the best effect. One has to keep various considerations in mind while applying textual items in Graphical User Interface. This article illustrates a few inventions on presenting textual items in a Graphical user Interface.; Comment: 9 pages, 6 figures

The FluorMODgui Graphic User Interface (GUI) software package developed within the frame of the FluorMOD project Development of a Vegetation Fluorescence Canopy Model is presented in this manuscript. The FluorMOD project was launched in 2002 by the European Space Agency (ESA) to advance the science of vegetation fluorescence simulation through the development and integration of leaf and canopy fluorescence models based on physical methods. The design of airborne or space missions dedicated to the measurement of solar-induced chlorophyll fluorescence using remote-sensing instruments require physical methods for quantitative feasibility analysis and sensor specification studies. The FluorMODgui model developed as part of this project is designed to simulate the effects of chlorophyll fluorescence at leaf and canopy levels using atmospheric inputs, running the leaf model, FluorMODleaf, and the canopy model, FluorSAIL, independently, through a coupling scheme, and by a multiple iteration protocol to simulate changes in the viewing geometry and atmospheric characteristics. Inputs for the FluorMODleaf model are the number of leaf layers, chlorophyll a+b content, water equivalent thickness, dry matter content, fluorescence quantum efficiency...

As we approach the end of the century and enter into a digital era there is a need to concentrate on new methods of communication. The expansion of personal computers into the industrial sector and more recently into the home, has brought the ability to transmit various forms of data to the average user. This new ability is accompanied with a responsibility to communicate effectively and clearly. This study focuses on the ability of user interfaces to effectively communicate combinations of visual and auditory cues to produce a more comprehensive user experience. This work proposed that the addition of auditory cues to a graphical user interface allows the user to receive valuable feedback through multiple sensory channels. By combining the types of perceived stimuli, developers of user interfaces can effectively communicate with the user. Modification of Kodak's Picture Easy v.2.0 software allowed for the study of varying amounts of auditory stimuli incorporated into a graphical user interface. The hypothesis states that "by adding an appropriate level of non-verbal auditory cues, users will experience enhanced performance and understanding of a user interface." The augmentation of an existing application permitted the study of three prototypes varying in the level of auditory and visual stimuli. Users evaluated three combinations of the test application to determine the preferred level of nonverbal auditory feedback. The findings from this study may then be applied to the development of graphical user interfaces that permit the use of auditory cues. Although this research disproved the hypothesis and stated that participants preferred visual cues over auditory cues...
