Doctor of Philosophy / The rapid increase in available information has lead to many attempts to automatically locate patterns in large, abstract, multi-attributed information spaces. These techniques are often called data mining and have met with varying degrees of success. An alternative approach to automatic pattern detection is to keep the user in the exploration loop by developing displays for perceptual data mining. This approach allows a domain expert to search the data for useful relationships and can be effective when automated rules are hard to define. However, designing models of the abstract data and defining appropriate displays are critical tasks in building a useful system. Designing displays of abstract data is especially difficult when multi-sensory interaction is considered. New technology, such as Virtual Environments, enables such multi-sensory interaction. For example, interfaces can be designed that immerse the user in a 3D space and provide visual, auditory and haptic (tactile) feedback. It has been a goal of Virtual Environments to use multi-sensory interaction in an attempt to increase the human-to-computer bandwidth. This approach may assist the user to understand large information spaces and find patterns in them. However, while the motivation is simple enough, actually designing appropriate mappings between the abstract information and the human sensory channels is quite difficult. Designing intuitive multi-sensory displays of abstract data is complex and needs to carefully consider human perceptual capabilities, yet we interact with the real world everyday in a multi-sensory way. Metaphors can describe mappings between the natural world and an abstract information space. This thesis develops a division of the multi-sensory design space called the MS-Taxonomy. The MS-Taxonomy provides a concept map of the design space based on temporal, spatial and direct metaphors. The detailed concepts within the taxonomy allow for discussion of low level design issues. Furthermore the concepts abstract to higher levels, allowing general design issues to be compared and discussed across the different senses. The MS-Taxonomy provides a categorisation of multi-sensory design options. However, to design effective multi-sensory displays requires more than a thorough understanding of design options. It is also useful to have guidelines to follow, and a process to describe the design steps. This thesis uses the structure of the MS-Taxonomy to develop the MS-Guidelines and the MS-Process. The MS-Guidelines capture design recommendations and the problems associated with different design choices. The MS-Process integrates the MS-Guidelines into a methodology for developing and evaluating multi-sensory displays. A detailed case study is used to validate the MS-Taxonomy, the MS-Guidelines and the MS-Process. The case study explores the design of multi-sensory displays within a domain where users wish to explore abstract data for patterns. This area is called Technical Analysis and involves the interpretation of patterns in stock market data. Following the MS-Process and using the MS-Guidelines some new multi-sensory displays are designed for pattern detection in stock market data. The outcome from the case study includes some novel haptic-visual and auditory-visual designs that are prototyped and evaluated.

Neste trabalho, tratamos o problema de representação da topologia de triangulações e mapas de dimensão arbitrária. Estudamos a utilização de uma representação baseada em grafos de arestas coloridas, já utilizada como ferramenta teórica, mas nunca empregada em aplicações práticas. A principal limitação desta representação é a relativa inflexibilidade imposta sobre a manipulação da topologia. Há porém grandes vantagens em sua utilização, como a simplicidade de representação e a generalidade. Este trabalho consiste na especificação teórica de uma estrutura de dados baseada nestes grafos coloridos e de operações topológicas para construção e manipulação da estrutura. A utilização desta estrutura é ilustrada através de algoritmos para resolução de problemas em geometria computacional / Abstract: Maps are subdivisions of topological spaces into simple regions, and triangulations are a specific kind of map wherein each element is a simplex (edge, triangle, tetrahedron, etc). In this work, we analyze the problem of representing the topology of triangulations and maps with arbitrary dimension. We study a representation based on edge-colored graphs, already used as theoretical tool, but never employed in practical applications. The main limitation of this representation is the relative inexibility imposed on the manipulation of topology. There are, though, great advantages in its use, as its simplicity and generality. This work consists in the theoretic specification of a data structure based on these colored graphs and of topological operators to build and manipulate the structure.The use of this structure is illustrated by algorithms for computational geometry problems / Doutorado / Computação Grafica / Mestre em Ciência da Computação

A comparison is made between octrees, which are regular decompositions of volumes, and new, irregular decompositions called R-trees. This comparison is made within the context of the volume intersection problems that might be associated with an automatic inspection system. The results show that the irregular decomposition is independent of object position and can provide a more space efficient encoding for certain shapes. However, detecting intersections between R-trees requires an algorithm of greater complexity due to the irregularity of the decomposition. Algorithms are given for obtaining tree decompositions from a hierarchic relational model of a volume. Among these algorithms is a procedure for finding the minimal enclosing rectangular parallelepiped of a boundary representation, and a generalization of the point-in-polygon algorithm to boundaries on curved surfaces. Both of these algorithms have computation times that are proportional to the total number of components of the boundary's representation. / Master of Science

The Future Will Be Better Tomorrow is a satirical post-apocalyptic novel that examines the personal and social ironies that occur in a society that is unbalanced by an unexplained apocalyptic event. Working with a combination of dark humor and the terrifying realities of an apocalyptic event – in this case: a blackout – the novel aims to challenge the machinery established by this particular subset of the science fiction genre. / Includes bibliography. / Thesis (M.F.A.)--Florida Atlantic University, 2014.. / FAU Electronic Theses and Dissertations Collection

This research addresses the need for increased interoperability between the varied access control systems in use today, and for a secure means of providing access to remote physical devices over untrusted networks. The Universal Physical Access Control System (UPACS) is an encryption-enabled security protocol that provides a standard customizable device control mechanism that can be used to control the behavior of a wide variety of physical devices, and provide users the ability to securely access those physical devices over untrusted networks. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2015. / FAU Electronic Theses and Dissertations Collection
