Neste trabalho é apresentado um conjunto de contribuições teóricas e práticas que buscam solidificar alguns conceitos da teoria dos dispositivos adaptativos baseados em regras, enfatizando a sua alta aplicabilidade. Uma ferramenta de apoio ao desenvolvimento de autômatos adaptativos, incluindo recursos de animação gráfica, foi desenvolvida de acordo com uma nova proposta de formalização que deverá complementar e simplificar a proposta original. A principal complementação está relacionada com a interpretação e a implementação de funções adaptativas, em sua forma mais geral: com ações elementares de consulta podendo retornar resultados múltiplos. A nossa proposta de formalização, que inclui um algoritmo para a execução de funções adaptativas, é uma ferramenta importante na determinação do impacto da execução da camada adaptativa no cálculo de complexidade geral de um autômato adaptativo. A tese apresenta também uma técnica para a integração de dispositivos adaptativos, basicamente discretos, com mecanismos capazes de manipular informação não-discreta. É mostrado também como estes resultados teóricos e as ferramentas desenvolvidas podem ser aplicadas na solução de problemas nas áreas de aprendizagem computacional...

O presente trabalho consiste em desenvolver e aplicar um método para avaliar comparativamente modelos distintos de interfaces gráficas computacionais, quando empregados como ferramenta de auxílio ao ensino e aprendizado de Geometria Gráfica para um específico grupo de usuários. A motivação que originou esta pesquisa foi a necessidade de avaliar, comparativamente, a interface inovadora de um programa de desenho denominado Risko, que foi desenvolvido com o propósito de atender às necessidades específicas do ensino de desenho. Como diferencial, o aplicativo usa, em sua interface, uma metáfora do mundo real e apresenta instrumentos de desenho virtuais: compasso, esquadros, lápis e borracha, que substituem as ferramentas abstratas (ícones e menus) inerentes ao padrão "WIMP" que é a alternativa largamente utilizada pelos aplicativos destinados ao ensino do tema. O método proposto utiliza-se de dois instrumentos: um teste prático com usuários e um questionário. Os testes com as interfaces são realizados tanto por usuários iniciantes quanto por aqueles já experientes com elas, registrando-se o número de erros cometidos bem como o tempo para completar tarefas pré-definidas, em ambas as interfaces. O questionário procura avaliar aspectos subjetivos como preferência por uma ou outra interface e percepção de precisão. Os resultados são todos analisados de forma comparativa entre as interfaces e o nível de significância é controlado estatisticamente.. A avaliação das interfaces contribui para o desenvolvimento das ferramentas computacionais educativas apontando as falhas e virtudes dos aplicativos em questão. Em linhas gerais...

Um dos grandes desafios para a reabilitação de indivíduos que sofreram traumas resultando na sua incapacidade de interação com o ambiente é o desenvolvimento de um sistema que possibilite a esse indivíduo a mínima capacidade de comunicação. Em casos extremos, indivíduos perdem os movimentos dos membros superiores, pescoço e a capacidade de comunicação por voz, ficando praticamente isolados do ambiente. O sistema de controle por imagem proposto é baseada na interpretação de seqüências de imagens que compõem movimento do globo ocular, usando como elemento de controle a região da pupila iluminada por diodos emissores de luz (LED's) de infravermelho. A tomada de decisão do sistema para a interpretação do movimento do globo ocular utiliza um controlador baseado em lógica fuzzy, que classifica o movimento do globo ocular em padrões pré-determinados e gera um sinal de controle, que pode ser utilizado para o acionamento de um hardware ou software adicionais, conforme a utilização do sistema proposto. O objetivo do presente trabalho é o desenvolvimento de uma interface homem-máquina de baixo custo, permitindo acesso desses indivíduos ao computador pessoal.; One of the biggest challenges for rehabilitation of people that suffered traumas resulting in environment iterating inabilities is a system development that allows this individuals the minimal communication ability.

Transcranial focused ultrasound (FUS) is capable of modulating the neural activity of specific brain regions, with a potential role as a non-invasive computer-to-brain interface (CBI). In conjunction with the use of brain-to-computer interface (BCI) techniques that translate brain function to generate computer commands, we investigated the feasibility of using the FUS-based CBI to non-invasively establish a functional link between the brains of different species (i.e. human and Sprague-Dawley rat), thus creating a brain-to-brain interface (BBI). The implementation was aimed to non-invasively translate the human volunteer’s intention to stimulate a rat’s brain motor area that is responsible for the tail movement. The volunteer initiated the intention by looking at a strobe light flicker on a computer display, and the degree of synchronization in the electroencephalographic steady-state-visual-evoked-potentials (SSVEP) with respect to the strobe frequency was analyzed using a computer. Increased signal amplitude in the SSVEP, indicating the volunteer’s intention, triggered the delivery of a burst-mode FUS (350 kHz ultrasound frequency, tone burst duration of 0.5 ms, pulse repetition frequency of 1 kHz, given for 300 msec duration) to excite the motor area of an anesthetized rat transcranially. The successful excitation subsequently elicited the tail movement...

PILOT is a programming system constructed in LISP. It is designed to facilitate the development of programs by easing the familiar sequence: write some code, run the program, make some changes, write some more code, run the program again, etc. As a program becomes more complex, making these changes becomes harder and harder because the implications of changes are harder to anticipate. In the PILOT system, the computer plays an active role in this evolutionary process by providing the means whereby changes can be effected immediately, and in ways that seem natural to the user. The user of PILOT feels that he is giving advice, or making suggestions, to the computer about the operation of his programs, and that the system then performs the work necessary. The PILOT system is thus an interface between the user and his program, monitoring both in the requests of the user and operation of his program. The user may easily modify the PILOT system itself by giving it advice about its own operation. This allows him to develop his own language and to shift gradually onto PILOT the burden of performing routine but increasingly complicated tasks. In this way, he can concentrate on the conceptual difficulties in the original problem...

Despite the significant effort devoted to methods for expression recognition, suitable training and test databases designed explicitly for expression research have been largely neglected. Additionally, possible techniques for expression recognition within an Man-Machine-Interface (MMI) domain are numerous, but it remains unclear what methods are most effective for expression recognition. In response, this thesis describes the means by which an appropriate expression database has been generated and then enumerates the results of five different recognition methods as applied to that database. An analysis of the results of these experiments is given, and conclusions for future research based upon these results is put forth.; by James P. Skelley.; Thesis (M.

Recentemente nosso grupo de pesquisa desenvolveu uma interface homem-computador, denominada Muscle Academy, baseada na atividade elétrica detectada a partir da superfície de músculos (eletromiografia – EMG). Neste estudo foram avaliados 40 indivíduos, sendo 30 indivíduos sem disfunções em membros superiores e 10 indivíduos com disfunções em membros superiores, visando avaliar o uso do Muscle Academy em diferentes situações. Os 30 indivíduos sem disfunções em membros superiores foram divididos em 3 grupos de 10 pessoas cara, que realizaram o protocolo experimental utilizando diferentes distâncias entre os botões a serem clicados (GI com distância de 4 cm; GII com distância de 7,5 cm e GIII com distância de 15 cm) e o grupo indivíduos com disfunções em membros superiores realizou a pesquisa com distância de 15 cm entre os botões a serem clicados. Os resultados mostraram que houve diferença significativamente estatística entre o tempo (ms) médio gastos para ir de um botão para o próximo e clicar os grupos experimentais, principalmente quando comparados os grupos sem disfunções em membros superiores e com disfunções em membros superiores, ambos com mesma distância entre botões, porém, a evolução dos fatores de aprendizagem de todos os indivíduos foi semelhante...

Um die mechanischen Eigenschaften biologischer Systeme in Computersimulationen untersuchen zu können, wurden geeignete Modelle erstellt, deren Eigenschaften durch physikalische Gesetze bestimmt sind. Das Ziel dieser Arbeit war es, ein biomechanisches Menschmodell zu erstellen, mit dem sich die mechanische Wechselwirkung des Menschen mit seiner Umwelt durch Simulationen analysieren lässt. Im Rahmen dieser Arbeit wurden Starrkörpermodelle des Menschen erstellt, wobei zur Aufstellung und Lösung der Bewegungsgleichungen kommerzielle Programmpakete (z.B. SIMPACK und ADAMS) verwendet wurden. Das entwickelte Menschmodell wurde in zwei konkreten Anwendungsbeispielen eingesetzt. Zum Einen wurden zwei Unfälle zwischen Fußgänger und PKW simuliert und die Ergebnisse wurden mit denen aus der klassischen forensischen Rekonstruktion verglichen. Zum Anderen wurde die Vibrationseinleitung beim menschlichen Hand-Arm-System untersucht. Es wurde gezeigt, dass die Berücksichtigung der elastischen Eigenschaften der Weichteile durch sogenannte Schwabbelmassen bei dieser Anwendung notwendig erscheint. Beide Anwendungen zeigten, dass biomechanische Starrkörpermodelle bezüglich ihrer Sensitivität im Bezug auf Systemparameter untersucht werden können. Daher sind Starrkörpermodelle geeignet...

Ein Brain-Computer-Interface-System (BCI) bietet schwerstgelähmten Patienten eine Möglichkeit zu kommunizieren. Während sie verschiedene mentale Aufgaben ausführen, was kurzzeitig zu unterschiedlichen mentalen Zuständen führt, werden die Gehirnsignale der Patienten aufgezeichnet. Aus diesen Signalen extrahiert ein Computersystem zuerst komplexe Merkmale und übersetzt diese in einem zweiten Schritt in Kontrollsignale zur Steuerung einer Kommunikationsanwendung. Extraktion und Übersetzung der Signale werden durch z.T. lernende Algorithmen realisiert, welche für jeden Benutzer individuell angepasst werden müssen, um eine optimale Leistungsfähigkeit des BCI-Systems zu erzielen. Einer der zu optimierenden Schritte ist die Selektion einer geeigneten Menge von Merkmalen. Diese Merkmalsmenge soll eine möglichst exakte Unterscheidung der mentalen Zustände ermöglichen, durch Einblick in die Lösung das Verständnis für diesen Lösungsansatz erhöhen, den experimentellen Aufwand absenken und damit die Akzeptanz für das BCI-System bei den Benutzern erhöhen. Sieht man EEG Elektroden als Merkmale an, so ist die Auswahl einer kleineren Merkmalsmenge äußerst wünschenswert - sie verkleinert den immensen täglichen Aufwand für das Setzen der Elektroden vor dem Beginn der Kommunikation per BCI. Das Problem der Merkmalsselektion ist außerordentlich schwierig zu lösen...

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...

CAPS (Computer Aided Prototyping System) is an integrated set of software tools that generate prototypes directly from real time requirements. The success of CAPS depends on being able to generate the prototype quickly so that it can be evaluated, leading to the construction of a program built on true requirements thereby resulting in a better software product. The key to developing prototypes quickly is having a significant software base to choose reusable components from. The problem with the current version of CAPS is that there exists no software base storage facility. This thesis utilizes the Ontos database to build the object oriented conceptual design for the data object repository and uses TAE to create the graphical user interface to access the repository. It further explores various searching techniques to deterniine the best possible implementation of the repository search engine. The results of this thesis are a conceptual design that can be used to implement the software base and an interface which provides a fluid, intuitive, interactive environment in which the user will be able to manipulate the database when actually built It further identifies the multi-level filtering technique as the best candidate for searching the database...

Approved for public release, distribution unlimited; The U.S. Navy has recently embarked on a program called Next Generation Computer Resources (NGCR) whose aim is a cooperative effort between Navy and industry to field a set of state of the art computers for shipboard use in the late 1990's. One of the important features of NGCR is the use of commercial hardware developed to standardized protocol and ruggedized for military applications. This protocol provides for compatibility between machines. The machines themselves may be of any architecture so long as they can meet the protocol requirement as specified by NGCR protocol, while not fully defined, implies the use of microprocessor based workstations. The Naval Sea Systems Command in an effort to keep pace with combat system software, desires experience in developing software targeted for commercially available NGCR machines (workstations). This study provides a detailed set of initial requirements for such a system. The approach is to implement the basic features of a Combat Direction System (CDS) on a microprocessor based workstation. This low cost CDS (LCCDS) will initially be installed on non-combatant vessels which currently have no computer processing capability at all. Eventually the LCCDS may be used to augment current processing capability of CDS equipped combatants followed by future systems designed around high speed (SAFENET) networks of tactical workstations.

In the scheme of an integrated decision support system, model management holds a position comparable with data management. Unfortunately, the development and formalizing of model management techniques historically have lagged far behind data management concepts, although the increased interest in spreadsheets has rekindled an interest in models as productivity enhancing tools. Model management systems offer one way of integrating models into the overall structure of an organizational information resource library. This thesis proposes the design and implementation of a visual interface to one such model management system, based on A.M. Geoffrion's structured modeling paradigm. Our goal is to provide the user with a natural, easy-to-use interface that is, at the same time, powerful enough to extract the full potential from a model management system.

The problem addressed in this research is the need for supervisory or system summary displays for the Advanced Tomahawk Weapons Control System (ATWCS). These displays are needed to accurately depict the current system state and weapon status in order to aid strike supervisory personnel in making correct and timely decisions. This research examined the problem in the context of designing a set of graphical displays that extracts information relevant to the strike supervisor from ATWCS and displays it in a manner that allows both rapid and accurate interpretation. The approach used to solve the problem progressed in four distinct phases. The first phase, Requirements Analysis, consisted of gathering system requirements through interviews with U.S. Navy officers who have experience as strike warfare supervisors. In the second phase, an initial design was produced using Century Computing's rapid prototyping tool TAE Plus Workbench(TM). The third phase involved the heuristic and guideline evaluation of the prototype based on accepted user interface design principles and ATWCS user interface requirement specifications. This evaluation produced a second iteration prototype that was used in the final phase, Usability Testing. The prototype was tested by U.S. Navy Officers with Tomahawk strike experience and test results were recorded. Changes were then made to the prototype to correct usability problems discovered by the user testing...

Thumb interaction is a primary technique used to operate small handheld devices such as smartphones. Despite the different techniques involved in operating a handheld device compared to a personal computer, the keyboard layouts for both devices are similar. A handheld device keyboard that considers the physical capabilities of the thumb may improve user experience. We developed and applied a design evaluation tool for different geometries of the QWERTY keyboard using a performance evaluation model. The model utilizes previously collected data on thumb motor performance and posture for different tap locations and thumb movement directions. We calculated a performance index (PITOT, 0 is worst and 2 is best) for 663 designs consisting in different combinations of three variables: the keyboard's radius of curvature (R) (mm), orientation (O) (°), and vertical location on the screen (L). The current standard keyboard performed poorly (PITOT = 0.28) compared to other designs considered. Keyboard location (L) contributed to the greatest variability in performance out of the three design variables, suggesting that designers should modify this variable first. Performance was greatest for designs in the middle keyboard location. In addition...

A Human Computer Interface (HCI) System for playing games is designed here for more natural communication with the machines. The system presented here is a vision-based system for detection of long voluntary eye blinks and interpretation of blink patterns for communication between man and machine. This system replaces the mouse with the human face as a new way to interact with the computer. Facial features (nose tip and eyes) are detected and tracked in realtime to use their actions as mouse events. The coordinates and movement of the nose tip in the live video feed are translated to become the coordinates and movement of the mouse pointer on the application. The left or right eye blinks fire left or right mouse click events. The system works with inexpensive USB cameras and runs at a frame rate of 30 frames per second.; Comment: IEEE format, International Journal of Computer Science and Information Security, IJCSIS January 2010, ISSN 1947 5500, http://sites.google.com/site/ijcsis/
