A geração automatizada de Interfaces de Usuário (IU) é objeto de estudo há muitos anos. Desde a década de 80, dezenas de projetos foram desenvolvidos e várias soluções apresentadas ao mercado. Entretanto, mesmo com os avanços obtidos neste cenário, inúmeras dificuldades ainda continuam presentes no dia-a-dia dos desenvolvedores de sistemas. A necessidade de processos, sintaxes e linguagens proprietárias associado ao elevado esforço de configuração e à baixa reutilização de tecnologias são os principais problemas nessa área. Objetivando sanar essas dificuldades, este trabalho propõe uma solução diferenciada para o problema, a qual reutiliza e integra-se à maioria das tecnologias comumente presentes nos ambientes de desenvolvimento e que conta com um exclusivo sistema de configuração, capaz de minimizar o trabalho de geração das IU. Sendo um típico gerador baseado em modelos, o software proposto é chamado MERLIN, e objetiva automatizar completamente a geracão de interfaces CRUD, as quais estão presentes em até 30% dos sistemas que operam sobre banco de dados. Para alcançar este objetivo, o software aposta no uso intensivo de heurísticas e na formação de uma estrutura auto-contida e realimentada de configurações, a qual reside unicamente nas classes compiladas da aplicação. Completando a sua arquitetura, um processo de geração em tempo de execução inibe a produção de qualquer linha de código-fonte, o que evita a necessidade de refatoração ao longo da evolução dos sistemas. Com esses elementos em evidência e focando inicialmente a plataforma Java, sinaliza-se uma solução diferenciada, apta para ser utilizada em ambientes profissionais de desenvolvimento. / The automated generation of User Interfaces (UI) has been the object of study for many years. Since the 1980s, dozens of projects have been developed and various solutions presented to the market. However, even with the advances obtained under this scenario, innumerable difficulties still continue to present themselves in the daily routine of system developers. The demands of proprietary methodologies, syntaxes and languages, the high level of effort needed for configuration and low reuse of technologies are the main problems in the area. With the object of rectifying these difficulties, this work proposes a solution specific to the problem, which reuses and combines the majority of the technologies already existing in development environments and relies on an exclusive configuration system, capable to minimize the work of generating the UI. Being a typical model based generator, the software under consideration is called MERLIN, and has as its objective to completely automate the generation of CRUD interfaces, which are present in up to 30% of the systems that interact with data bases. To achieve this objective, the software relies on the intensive use of heuristics and the creation of a self contained configuration feedback structure, which exists solely in the compiled classes of the application. Completing this architecture, a process of execution time generation eliminates the need for any source code, which significantly reduces the costs of refactoring the code throughout the evolution of the systems. With these elements in evidence and focusing initially on the Java platform, indicates that this distinguished solution is ready for use in professional development environments.

ERIAN is a complex business rule management system developed by com- pany Komix. Part of this system is the Rule Management Interface (RMI) which allows users to create, edit, schedule, test and otherwise manage their business rules. The RMI is implemented as a thick client based on C# and WPF, which has its disadvantages. This thesis provides a prototypical implementation of the RMI as a thin client based on cutting-edge web technologies. This thesis predominantly deals with the choice of the correct technologies for the task, while allowing develop- ment and maintainance of different customized versions of the RMI and making sure the prototype handles working with business rules seamlessly even if they are exceptionally large. The resultant RMI prototype is well testable and adds several new function- ality features, compared to the original. It lays a good foundation for a complete re-implementation of the RMI as a thin client.

This thesis investigates embedded databases and graphical interfaces for the MicroBaseJ project. The project aim is the development of an integrated database and GUI user interface for a typical 3G, or 2.5G, mobile phone with Java MIDP2 capability. This includes methods for data acquisition, mobile data and information communication, data management, and remote user interface. Support of phone delivered informatics will require integrated server and networking infrastructure research and development to support effective and timely delivery of data for incorporation in mobile device-based informatics applications. A key research and development (R&D) challenge is to support effective and timely delivery of data for incorporation in mobile device-based informatics applications. Another important aspect of the project is determining how to develop efficient graphics for the small mobile screen. The research investigates and analyses the architecture of a mobile monitoring system. The project developed a generic solution that can be implemented in a number of commercial sectors, such as horticulture, building management and pollution/water management. The developed concept is tested using data relevant to the horticultural area of application. The system also addresses the main issues related to mobile monitoring, including real-time response, data integrity, solution cost, graphical presentation, and persistent storage capabilities of modern mobile devices. Four embedded databases based on J2ME have been investigated. Two of the four have been evaluated and analysed. The Insert function, Sequence Search, and Random Search of Perst List and RMS (Record Management System) databases have been tested. The size of the processed data was limited to 20,000 records when using the wireless toolkit simulator, and 11,000 records when using a mobile phone. Perst Lite reflects good performance and has out-performed RMS in all tests. User interface software such as J2ME Polish for mobile phones has been investigated. Custom J2ME class for graphical interface is developed. This provides the graphical presentation of the data collected from the sensors; including temperature, wind speed, wind direction, moisture, and leaf wetness. The graphical interface, bar charts, and line charts with trace ball for collected data have been designed and implemented. The embedded database performance and project performance have been investigated and analysed. The performances of Perst Lite and RMS are evaluated in terms of the insert, sequence search, and random search functions based on simulation and real devices. The record numbers vary from 1,000 to 20,000. The project performance contains data receiving and storage, and data presentation and configuration. The performance of data storage and configuration can be negated due to the running mode and the response time. Thus, data presenting performance is the key focus in this project. This performance was divided into the categories of initial, data search, data selection, and charting. The initial performance includes the initialisation of the project parameters, and the reaching of the welcome interface. Data search performance refers to the retrieval of the specified data from the embedded database, measured on 48 data points, which only can be presented on the mobile screen from the retrieved data. These four performance types are measured in thousands of record numbers, varying from 1,000 to 18,000 record numbers, with the retrieved data range varying from 1 day to 30 days.

The familiar computer graphic user interface (GUI) makes extensive use of visually representative devices such as folders and files. These symbols help the user deal with computer data and operations that otherwise have little or no physical form. The computer’s underlying complexity is symbolised for the user, who is then able to manipulate the computer by interacting directly with the interface. The early development of computer interface design was largely the domain of software and hardware developers. Many sound principles of user interaction and testing were established and provided essential guidance for new generations of interface designers. As computer technology and its tools became more widely available, a broader range of designers began contributing, including those from product design and visual communication. This study is written from the point of view of a “visual designer” – a designer who began his career in graphic design and who has moved towards interface design out of curiosity and a desire to proffer a different attitude and approach to interface issues. The study therefore will demonstrate a design process that many visual designers will be able to identify with. The process includes research, analysis, methodical progression and artistic inspiration. The artistic inspiration in this case comes from the Constructivist artist El Lissitzky, and will illustrate the significant contribution that art can make to interface design. This art-influenced design process was presented at the 2005 Ed-Media World Conference on Educational Multimedia, (Montreal, 2005). The enthusiastic response and discussion provided encouragement to continue in this direction. In the following year another presentation, which included the working prototype, was presented as part of a keynote speaker presentation at the 2006 Siggraph Taipei Conference, National Chiao Tung University, Taipei. The specific task chosen to work with in this study is that of Web browser history. As a user browses the Web the computer records a list of visited websites. The first few generations of browsers presented this information as a simple list, but this approach incorporated many flaws and caused problems for users. More recent browsers provide more options, but significant issues remain. This study offers solutions to several of these problems. The resulting design prototype is named “isoBrowser”. It is the result of the alternative design process outlined above and offers alternative methods of visualising, organising and manipulating data. The prototype is not intended to be fully functional nor “live”. However, it is sufficiently operable so as to test interface interaction and user response. A fully functional version, operably and aesthetically complete, would be the subject of further development.

The Internet is a vastly under-utilised resource, only used for half of the IT story. Describe the Internet in two words and many might say ‘sharing knowledge’. But sharing information is more accurate. It’s just that all the principle ways we use the Internet — the Web, email and media streaming — happen to be examples where information is in the form of knowledge. But IT — Information Technology — has another side: the realm of software programming where information means the dynamic control of how things work. The Internet is the driving force in the IT industry, so why isn’t it also known for sharing control? True, there are examples of specialised, one-off software applications interfacing with each other via the Internet, but there has yet to be any systematic and universal attempt to exploit the potential of the Internet for control-IT in the way we have seen it for knowledge-IT. Taking the strengths of the Web model as a starting point, this thesis proposes a parallel, dynamic world to the Web called The Mesh. In the same way that the Web seamlessly connects databases of the world to provide a global font of knowledge, the Mesh would connect software of the world to provide a global means of control. The Mesh would embody all the successful, empowering features of the Web. Everyone would have a say in how things work, mirroring Web 2.0’s user-generated content but for software instead of media. In being a universally integrated design approach for device control, the Mesh would encompass a number of research areas working on the control issue at the big picture level. It would address the problems of universal usability and ubiquitous computing. It would also provide solutions in agent-based systems and grid computing. But many features of the Mesh would simply be unique. They would change the way we go about software design, leading to new opportunities for users, programmers and manufacturers alike. The key to everything is design simplicity. A concept demonstrator has been developed as an integral part of this research project. It shows that the Mesh is both feasible and practical. Examples of programs run in the concept demonstrator are discussed, showing exactly how the Mesh would be built and how it would work. / Thesis (Ph.D.) -- University of Adelaide, School of Electrical and Electronic Engineering, 2007

<p>In the future network-based Swedish Defence (NBD), attaining information superiority will be of great importance. This will be achieved by a network of networks where decision-makers, information- and weapon-systems are linked together. As a part of the development of NBD, we have performed a study of user interface design for a future network-based tool package for analysis of sensor systems, referred to as the C2SR-system. </p><p>This thesis was performed at Ericsson Microwave Systems AB, Sensor and Information Networks, during the autumn 2002. A pre-study concerning the requirements of usability, trustworthiness and functionality of a userinterface for the C2SR-system was performed. Officers representing the future users in the NBD played an important role when gathering these requirements. Another important part of the pre-study was the evaluation of software that contains parts of the functionality necessary for the C2SR-system. </p><p>On the basis of the results from the pre-study, we have designed a user interface to the future C2SR-system. To demonstrate the most important conclusions, a prototype was implemented.</p>

<p>Browsing the Web on a distant screen may very often become user’s unpleasant experience. Such a situation may happen in a living room environment, where the user attempts to browse the Web on TV sitting at 10-foot distance from the screen. In a vast number of web sites that the user is able to request, many may contain, for instance, tiny text characters, which would become unreadable when watched from the distance. On the other hand, also navigation through the Web offerings can become troublesome. Especially, when the user is only equipped with the commonly used remote controller, interaction with the displayed content may prove inefficient. Therefore, methods to overcome content visibility and navigation problems become challenging. In this thesis we perceive living room environment as a good scenario, in which web-enabled handheld devices could further be utilized to interact with Consumer Electronics products, such as TVs. This sort of interaction should make an advantage of publically available Web resources to have them displayed on TV and controlled from the distance by the user who is equipped with, for instance, a web-enabled mobile phone. We think that such an interaction approach would become beneficial in several ways, making the Web browsing routine an interactive, possibly a group activity. Discussed in this thesis solutions are the first step of automatic transformations of web content into a form that can be rendered on Web4CE (Web for Consumer Electronics) products. A particularly important aspect of the proposed system is the concept of request/response HTTP message processing and HTML modification. According to this approach, living room browsing activity should be achievable without the need to re-author already existing web sites.</p>

<p>This report is a part of a diploma work, conducted as a part of a Master of Science degree. The diploma work consists of a preliminary study, two case studies, a user study, a paper and this report. It was created at the Linköping University for the department of Science and Technology, in cooperation with Unilever Research in the UK, and partly with the EC founded project, Smartdoc IST-2000-28137. </p><p>Hand-held, mobile devices like Personal Digital Assistances (PDAs) are becoming increasingly popular in today’s wireless world. While trying to pack all the possible information into a small window, a nightmarish scenario is created for the interface designer to deal with. The goal for this project was to investigate different Visual User Interfaces (VUIs)on PDAs, and how to apply desktop interaction techniques to PDAs. </p><p>A VUI model based on Zooming User Interface (ZUI) techniques, to adapt two complete different visualisation application areas; on-line brand-based shopping and flood warning system for PDAs, is presented. The on-line brand- based shopping was evaluated in a benchmark usability study comparing it to traditional PC based on-line shopping.</p>

<p>The aim of this thesis project is to create a user interface for a web based film production project management portal. This implies creating a site map and a functionality specification based on the needs of the people working in the film production industry. The project was made on account of The Chimney Pot, a post production company in Stockholm. For the scope of this project, the research was concentrated on the part of film production that concerns The Chimney Pot, i.e. the procedures that take place after a film has been recorded. The research also focused on people working in the area of Stockholm, even if their clients and customers in other areas of Sweden and abroad were indirectly included in order for the project portal to be a usable tool in projects where these people are involved. </p><p>Before any visible results can be seen in a web production project, a range of preparation steps needs to be taken. Planning is essential if the final product shall work properly. Extensive research has to be done into the industry. In order to make the product usable, the intended users, their requirements, work procedures and environment need to be examined. Only when there are substantial results and enough knowledge about the industry, the actual implementation can start. The first step is to make a functionality specification, next a site map should be produced and the technical architecture should be specified. These are the areas that are covered in this project, but there are also recommendations about how the further development should be made. Important aspects in the next phase are to create a budget, to put together a development team and to create a graphic user interface. In the whole process the issues of usability need to be considered, i.e. efficiency, flexibility, learnability and satisfaction. </p><p>The key requirements for the project portal turned out to be speed and effectiveness. The user interface was designed to be intuitive and to be shallow, which means that the user should be able to perform any task with the least amount of mouse clicks possible. Another intention with the produced user interface is for it to be clearly divided into the four main areas that could be extracted from the user requirements. They are planning, project details, communication and file sharing. Directly after logging on to the project portal, the user should get an overview of all these areas. Other important considerations were security, version control and seamlessness. These issues demand a thorough planning of the technical architecture and this thesis provides some useful tips for the further development of the technical specification.</p>
