With the proliferation of media, connected to the World Wide Web, the opportunities of expression and creation of an increasing public have expanded. This technological advent, associated with the characteristics of the subject belonging to the concept called late modernity, is gradually changing social relationships. The motivation of this work comes from the urgency to signal the educational context, from basic education to the academic, on changes in the profile of its target audience, making it necessary to revise the methods so that these will add approaches to the emerging challenges. The first objective, from the theoretical framework and case study, aims to identify the characteristics of the subject influenced by the media consumerism, pointing to the transmedia storytelling as influences coming from the interactive consumer...
Tese de Doutoramento em Tecnologias e Sistemas de Informação - Área do Conhecimento Engenharia de Programação e dos Sistemas Informáticos
The theme of this report is information visualization. Nowadays, this is a very active and vital area of research, teaching and development. The basic idea of using computer generated pictures to gain information and understanding from data and relationships is the key concept behind it. This is an extremely simple, but very important concept which is having a powerful impact on methodology of engineering and science. This report is consisted of two parts. The first one, is an overview of the subtle correlation between the visual techniques, the user perception and the data. In the second part, several computer applications, tools, projects and information visualization systems are analyzed. In order to categorize them, seven basic types of data are considered: onedimensional, two- dimensional, three-dimensional, multidimensio...
There are several ways of analyzing and modeling the human body and its associated morphological and physiological data. Most of the models, used to analyze, to process and to visualize these data, do not take into account the strong spatial interdependency inherent to human body’s functioning. For instance, a disease in the liver might impact in several other organs. These models usually treat morphological and physiological data in a full independent and isolated way. This happens because they are not “spatially” oriented. The human body can be compared to a map, being composed by different parts and layers of information. The possibility of combining these layers using spatial algebraic operations, introduces a new degree of information insight. Because of these characteristics, it is important to consider and evaluate the de...
Doctors usually execute a spatial analysis when diagnosing a disease in a patient. This happens, because the human body is composed of several spatial interdependent layers of information, that describe its functioning and behaviour. The human body organs and systems are described by morphological and physiological data that should be spatially combined by the doctor in order to evaluate the global patient health condition. On the other hand, most of the models, used to analyze, to process and to visualize these data, do not take into account this strong spatial interdependency inherent to human body’s functioning. These models usually treat morpho-logical and physiological data in a full independent and isolated way. This happens because they are not “spa-tially” oriented, and do not interpret the human body as a 3D map, being compose...
The human body is composed of several systems and organs that have a specific and well located position within it. Each organ is usually related to one or more physiological data. There is a subtle spatial interdependency on human’s body structure and behaviour. Because of this, doctors usually execute a spatial analysis when diagnosing a disease in a patient. The doctor has to combine patient’s medical data performing some “implicit” algebraic map operation. Although this is true, most of the models used to analyze, to process and to visualize these data, do not take into account the strong spatial interdependency inherent to human body’s functioning. These models usually treat morphological and physiological data in a full autonomous and isolated way. This happens because they are not “spatially” oriented, and do not interpre...
Objective The main goal of the CHUB (cartographic human body) model is to introduce a cartographic approach that can assist the analysis, visualization and diagnosis of medical images and related data. Method Acartographic model is proposed as a reference framework for the development of computer systems and applications. This model accommodates subtle spatial features of these data that may facilitate diagnosis. Medical images and related data are structured into different “human-referenced” information layers. Algebraic map operations are used to combine these layers and achieve greater insights into the information content. Results Two case studies were considered to evaluate and validate the model: hydrokinetic therapy and the diagnosis of knee osteoarthritis. A prototype based on the CHUB model was implemented and t...
Medicine is a vast area of scientific inquiry that uses many computer imageprocessing applications such as x-rays, ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI). Besides image processing, computer graphics have addressed many other medical science issues, including human- body modeling, diagnostic decision-support, and training systems. Graphics provide a powerful means of delivering information, but if an advanced graphics application fails to process its input data properly, the graphics become worthless. A good visualization pipeline depends heavily on the application model that converts the data to graphics. Medical knowledge has distinct characteristics that any model in this domain must consider. It doesn’t typically deal with the kinds of data present in business applications. Inste...
