Computer screens are very small compared to the size of large information spaces that arise in many domains. The visualization of such datasets requires multiscale navigation capabilities, enabling users to switch between zoomed-in detailed views and zoomed-out contextual views of the data. Designing interfaces that allow users to quickly identify objects of interest, get detailed views of those objects, relate them and put them in a broader spatial context, raise challenging issues. Multi-scale interfaces have been the focus of much research effort over the last twenty years.There are several design approaches to address multiscale navigation issues. In this thesis, we review and categorize these approaches according to their level of content awareness. We identify two main approaches: content-driven, which optimizes interfaces for navigation in specific content; and content-agnostic, that applies to any type of data. We introduce the content-aware design approach, which dynamically adapts the interface to the content. The latter design approach can be used to design multiscale navigation techniques both in 2D or 3D spaces. We introduce Arealens and Pathlens, two content-aware fisheye lenses that dynamically adapt their shape to the underlying content to better preserve the visual aspect of objects of interest. We describe the techniques and their implementation, and report on a controlled experiment that evaluates the usability of Arealens compared to regular fisheye lenses, showing clear performance improvements with the new technique for a multiscale visual search task. We introduce a new distortion-oriented presentation library enabling the design of fisheye lenses featuring several foci of arbitrary shapes. Then, we introduce Gimlens, a multi-view detail-in-context visualization technique that enables users to navigate complex 3D models by drilling holes into their outer layers to reveal objects that are buried into the scene. Gimlens adapts to the geometry of objects of interest so as to better manage visual occlusion problems, selection mechanism and coordination of lenses.

Εκτός από τα Τεχνητά Νευρωνικά Δίκτυα, ένα άλλο παρεμφερές πρόβλημα είναι αυτό της μοντελοποίησης των δομικών και λειτουργικών χαρακτηριστικών διαφόρων τμημάτων του Κεντρικού Νευρικού Συστήματος καθώς και των διαφόρων εγκεφαλικών λειτουργιών. Στόχος αυτής της διπλωματικής είναι η δημιουργία ενός μοντέλου του φυσιολογικού νευρώνα και της συγκρότησης νευρωνικών δικτύων που εμπλέκονται σε κάποια εγκεφαλική λειτουργία. Στην ανάπτυξη του μοντέλου λήφθηκαν υπόψη τα ιδιαίτερα νευροανατομικά χαρακτηριστικά και νευροφυσιολογικά χαρακτηριαστικά και οι ιδιότητες που σχετίζονται με τις υπό μελέτη εγκεφαλικές καταστάσεις.

In the past decade, the design and manufacturing of intelligent multipurpose underwater vehicles has increased significantly. In the wide range of studies conducted in this field, the flexibility and autonomy of these devices with respect to their intended performance had been widely investigated. This work is related to the design and manufacturing of a small and lightweight autonomous underwater vehicle (AUV) with vision capabilities allowing detecting and contouring obstacles. It is indeed an exciting challenge to build a small and light submarine AUV, while making tradeoffs between performance and minimum available space as well as energy consumption. In fact, due to the ever-increasing in equipment complexity and performance, designers of AUVs are facing the issues of limited size and energy consumption. By using a pair of thrusters capable to rotate 360o on their axis and implementing a mass shifter with a control loop inside the vehicle, this later can efficiently adapt its depth and direction with minimal energy consumption. A prototype was fabricated and successfully tested in real operating conditions (in both pool and ocean). It includes the design and embedding of accurate custom multi-purpose sensors for multi-task operation as well as an enhanced coordinated system between a high-speed processor and accustomed electrical/mechanical parts of the vehicle, to allow automatic controlling its movements. Furthermore, an efficient tracking system was implemented to automatically detect and bypass obstacles. Then, fuzzy-based controllers were coupled to the main AUV processor system to provide the best commands to safely get around obstacles with minimum energy consumption. The fabricated prototype was able to work for a period of three hours with object tracking options and five hours in a safe environment, at a speed of 0.6 m/s at a depth of 8 m.

This type of application has attracted the interest of researchers due the advantages in relation to others methods for controlling settings, especially when the system has a complex dynamics to be adjusted by traditional methods. The proposed computational tool GACT (Genetic Algorithm Control Tool) was developed to work as a Toolbox of MATLAB® software for use in control systems and is based on the joint application of Genetic Algorithms (GA) and the classical control theory. The GACT based on the advancement of the operating systems that are no longer fully handled by command lines, and now have an interactive graphical user interface. That is, the referred Toolbox allows the implementation of an intelligent control system in a way more simplified and interactive. The graphical user interface (GUI) was designed using the software GUIDE, integrated with MATLAB® in order to connect with the source code and block diagrams of the system to be controlled at the SIMULINK® / Uma nova ferramenta baseada no uso da inteligência computacional aplicada em sistemas de controle é apresentada.

This report describes an approach of creating a system identifying fruit and vegetables in the retail market using images captured with a video camera at- tached to the system. The system helps the customers to label desired fruits and vegetables with a price according to its weight. The purpose of the sys- tem is to minimize the number of human computer interactions, speed up the identification process and improve the usability of the graphical user interface compared to existing systems. To accomplish creating a system improving these properties, an idea of implementing machine learning to identify the products aroused. Instead of assigning the responsibility to the user, who usually iden- tify the products manually, the responsibility is given to a computer. To classify an object, different convolutional neural networks have been tested and retrained. The networks have been retrained on data sets collected from ImageNet. To improve the accuracy, the networks have also been retrained on images where the background environment is similar to the environment the networks are supposed to perform in. The networks tested in this report are MobileNet and Inception. The networks have different propagation time and varies in accuracy. MobileNet performs the classification about seven times faster than Inception, but Inception gives more accurate results. To improve the systems further, usability testing has been performed on the graphical user interface of existing system and resulted system. To test the usability, a heuristic evaluation has been performed in combination of a second test produced by the authors. The tests concluded that the resulted system was more user friendly compared to existing systems. The hardware of the system constitutes of a Raspberry Pi, camera, display, load cell and a case. The software includes Python-code to label an image, a graphical user interface to interact with the user and a server created with Node.js. The graphical user interface has been programmed with JavaScript supplemented with the React library. To conclude, implementing convolutional neural networks to classify images and developing a new user interface resulted in a faster identification process together with fewer usability flaws.

Fruto do desenvolvimento de pesquisa em ciência computacional, especificamente sobre a questão da interface gráfica de usuário e da interação homem-computador, bem como de um constante entrelaçamento das linguagens midiáticas com as formas expressivas da primeira metade do século citado, tiveram, com o surgimento da Internet e da World Wide Web, a tarefa de conectar o ser humano e a cultura elaborada pelo universo digital. Ao mesmo tempo a influência de recursos provenientes de meios consagrados em sua constituição, como a página retangular, o enquadramento, a perspectiva linear e a câmera subjetiva, imprimem-lhe um fator notadamente cultural, daí passarem a ser denominadas de interfaces culturais. Destacam-se dois formatos básicos pelos quais o processo comunicacional engendra interfaces: os mundos virtuais e as estruturas hipertextuais. Dentro dessa configuração de comunicação digital, a hipermídia torna-se um ambiente propício para a emergência de práticas e experimentações em novos meios, por isso enfatiza-se a formação do campo hipermidiático e uma proposta de análise da hipermídia. / Graphic interfaces of user are intellectual technologies that came to existence during the 70þs and 80þs, resulting from the development of years of research in computers, specifically on the matter of information management and man-computer interaction. With the advent of the Internet and, especially the World Wide Web, the interfaces (of the browser and of the application) have connected human being and the culture elaborated by the digital universe. On the other hand, they receive influence of resources coming from prior means in its constitution, such as the rectangular page, the framing, the linear perspective and the subjective camera, which are reused by the design of interface in the creation of new means. With these factors they are then called cultural interfaces. Two basic formats, through which information is managed in interfaces in the digital culture, are highlighted: the virtual worlds and hypertext structures. Within that technological and cultural configuration, hypermedia becomes a favorable environment for the emergence of practices and experiments in new means, and therefore emphasizes the formation of the hypermedia field and a proposal of analysis of the hypermedia.

As plataformas de Scaffold, por exemplo, permitem um aumento da produtividade dos desenvolvedores ao gerarem código a partir dos elementos do modelo conceitual. Porém,o código fonte de GUI gerado apresenta muita replicação, devido ao acoplamento ainda existente entre os componentes das telas de interface gráfica e as propriedades inerentes ao modelo conceitual da aplicação, dificultando a manutenção do software. Os padrões de renderização propostos por Welick et al. se apresentam como uma solução conceitual para este problema, através do mapeamento de metadados do modelo conceitual em componentes gráficos, organizando o código de GUI e reduzindo a replicação de código. Neste trabalho, tem-se como objetivo a criação de um arcabouço para o desenvolvimento de aplicações corporativas com arquitetura web moderna, com foco em GUI, baseado em padrões de renderização. O arcabouço permite que o desenvolvedor construa componentes de GUI sem acoplá-los aos elementos do modelo conceitual. A associação da GUI com o modelo conceitual é feita através de regras de renderização, que podem ser alteradas facilmente. O arcabouço proposto foi validado através de um estudo de caso, no qual foi demonstrada uma redução significativa na duplicação do código quando comparada às plataformas de Scaffold. / The modern enterprise web application development is based on the use of patterns and tools to enable rapid prototyping, ensuring separation between the business model and graphical user interface (GUI). The Scaffold frameworks, for example, allows an increase in productivity of developers to generate code from the elements of domain model. However, the GUI source code generated presents a lot of replications due to coupling still extant between GUI components and properties inherent to the domain model of the application, making it difficult to maintain the software. The rendering patters proposed by Welick et al. are presented as a conceptual solution to this problem by mapping domain model metadata to graphical components, organizing the GUI code and reducing code duplication. In this Work, we have aimed to create a framework for enterprise applications development with web modern architecture, focusing on GUI, based on rendering patterns. This framework allows the developer to build GUI components without engage to elements of domain model. The GUI link with domain model is made by rendering rules, which can be changed easily. The proposed framework was validated by a case study in which it was demonstrated a significant reduction in code duplication when compared to Scaffold frameworks.
