Projeto de uma arquitetura de hardware para visualização de imagens digitais / Design of a hardware architecture for displaying digital images

Paiva, Maria Stela Veludo de 20 November 1990 (has links)
Neste trabalho são apresentadas a implementação e avaliação da aplicação do processador gráfico TMS34010. O objetivo foi o desenvolvimento de um sistema para visualização de imagens com este processador, a ser integrado ao Tomógrafo por Ressonância Magnética, do Departamento de Física e Ciência dos Materiais. A fim de avaliar tanto os aspectos do \"hardware\" quanto às capacidades do processador, foram desenvolvidos dois sistemas: um com 16 cores, e outro com 256 níveis de cinza, ambos contendo uma interface serial para interligação de um \"mouse\" convencional para microcomputadores do tipo PC-AT. Através destes sistemas foram avaliados recursos tais como \"pan\" horizontal e vertical, divisão da tela ao meio, vídeo no modo entrelaçado, transparência, operações lógicas, e instruções de transferência de blocos de \"pixels\" / This work describes the implementation and evaluation of a TMS34010 graphics processor based system. The system was developed to be used for the visualization of Magnetic Resonance Images in the MR tomography system under development in our Department. To evaluate the design and the performance of the processor, two systems were developed: one capable to show pictures with 16 simultaneous colors, and a second one able to display pictures with a gray scale of 256 levels. Both systems are equipped with a serial interface supporting a conventional mouse as used for PC compatibles. The hardware developed was used to evaluate implementations of resources such as horizontal and vertical PAN, screen division, interlaced video, transparency, logic operations and pixels block transfer routines

Análisis de diseño gráfico ambiental del Sistema Metropolitano de Transporte de Lima / Analysis of environmental graphic design of the Metropolitan Transportation system of Lima

Chavez Enriquez, Danit Yofre 02 July 2019 (has links)
El congestionamiento vehicular es el segundo problema más grande de los limeños, este se debe a que el sistema de transporte actual tiene algunas deficiencias. Sin embargo, existen sistemas vehiculares que han tenido más éxito, como es el caso del Sistema Metropolitano de Transporte de Lima (Metropolitano). No obstante, este también presenta algunos déficits, sobre todo, en la aplicación del Diseño Gráfico Ambiental que no permite que los usuarios se desenvuelvan correctamente en sus instalaciones. Por esa razón el objetivo del presente trabajo es identificar los principales problemas encontrados en el Metropolitano para poder crear una propuesta de solución basada en las herramientas que brinda el Diseño Gráfico Ambiental para comprobar si es que la implementación de Diseño Gráfico Ambiental, haciendo uso de sus elementos acompañados del uso de branding, códigos visuales, y un método de proyecto enfocado a diseño en el Sistema Metropolitano de Transporte de Lima puede mejorar la experiencia del usuario. Para el presente trabajo se realizó una investigación a nivel exploratorio y de enfoque cualitativo, ya que el objetivo era hallar las causas por las cuales los usuarios no logran conectar totalmente con las instalaciones del Metropolitano. La propuesta fue el replanteamiento del sistema de Diseño Gráfico Ambiental que va acompañado de una nueva identidad de marca. El resultado de los test fue en su mayoría positivo y por lo tanto se puede decir que la hipótesis presentada fue validada en el presente trabajo. / Traffic congestion is the second largest of the limeans problem, this is due to that the current transport system has some shortcomings. However, there are vehicular systems who have had more success, as it is the case of the Metropolitan system of transportation of Lima (Metropolitan). However, this also presents some deficits in its environmental design that not allows that users can manage is correctly in its facilities. Therefore, so the objective of the present study is to identify the main problems encountered in the system Metropolitan Transportation of Lima (Metropolitan) in order to create a proposal for a solution based on tools that provides design Environmental to thus be able to check if it is a good implementation of environmental graphic design, making use of its elements accompanied by the use of branding, Visual codes, and a method of project focused on design in the Metropolitan system of Transportation of Lima will allow that their user experience is improved. This study was an Experimental investigation level exploratory and qualitative approach, since the objective was to find the causes by which the users unable to connect completely with the metropolitan facilities. The proposal was the implementation of a system of environmental design that goes along with a new identity. The result of the test was mostly favourable so we can say that the hypothesis presented was validated in this study. / Trabajo de investigación

Geolocalização, redes sociais e dispositivos móveis: proposta de sistema gráfico / Geolocation, social networks and mobile devices: proposition of a graphic system

Fernando Alvarus de Oliveira 24 September 2013 (has links)
A geolocalização, os dispositivos móveis cada vez mais sofisticados e eficientes e a disponibilidade instantânea de mapas de todos os lugares do mundo, permitiram o desenvolvimento de novos aplicativos, os chamados serviços baseados em geolocalização; além disso, as redes sociais online têm se consagrado como ferramentas de relações entre pessoas. A combinação destas tecnologias levou ao surgimento de programas como o Foursquare, que alcançou a marca dos 30 milhões de usuários em 2013, quatro anos depois de seu lançamento, o que mostra a importância deste tipo de aplicativo; através do estudo destes aplicativos, observa-se a valorização da vizinhança como fator de afinidade social. Da análise dos elementos de wayfinding, depreende-se que a cidade incorpora marcos com valor emocional. Ao final, é proposto um sistema gráfico que torne visíveis estas referências emocionais. / Geolocation, mobile devices increasingly sophisticated and efficient and instantaneous availability of maps from all over the world, allowed the development of new applications, the so-called geolocation based services, in addition, online social networks have been established as tools for relation between people. The combination of these technologies has led to the emergence of programs like Foursquare, which reached 30 million users in 2013, four years after its release, which shows the importance of this type of application; through the research of those applications, there is the appreciation of the neighborhood as a factor of social affinity. From the analysis of the wayfinding is implicit that the city incorporates marks with emotional value. A graphical system is proposed to turn visible these emotional references.

Optimización del diseño de interfaz del aplicativo móvil “Viajo Seguro-SMP” de la municipalidad de San Martin de Porres / Optimization of the interface designn of the mobile application “Viajo Seguro-SMP” of the municipality of San Martin de Porres

Esquives Sáenz, Katherinne Lizbeth 09 July 2021 (has links)
La Municipalidad de San Martin de Porres junto con la subgerencia de transporte del distrito desarrollaron el aplicativo móvil Viajo Seguro SMP en abril del 2019. El problema de comunicación que se encontró fue una interfaz que no aportaba a la experiencia del usuario de mototaxis y tampoco solucionaba el problema de informalidad en el distrito. Teniendo en cuenta que en la actualidad circulan más de 8000 mil vehículos menores, de los cuales solo 2800 son formales. Este problema se vuelve relevante para el diseño gráfico porque encontramos fallas en el diseño de interfaz y también la necesidad de un sistema gráfico donde el usuario pueda identificar de manera visual una mototaxi formal. La propuesta de solución es una mejora al aplicativo, dándole la función principal de pedir una mototaxi, y creando todo un sistema gráfico que apoye a la identificación de vehículos formales. Los resultados arrojaron una mejor experiencia en el usuario, haciendo que sea una opción más rápida y segura. / The Municipality of San Martin de Porres together with the district's transportation submanagement developed the Viajo Seguro SMP mobile application in April 2019. The communication problem found was an interface design that did not contribute to the motorcycle taxi user experience and nor did it solve the problem of informality in the district. Taking into account that currently more than 8,000 thousand smaller vehicles circulate, of which only 2,800 are formal. This problem becomes relevant for graphic design because we find flaws in the UI design and also the need for a graphic system where the user can visually identify a formal motorcycle taxi. The solution proposal is an improvement to the application, giving it the main function of ordering a motorcycle taxi, and creating a whole graphic system that supports the identification of formal vehicles. The results yielded a better user experience, making it a faster and safer option. / Trabajo de Suficiencia Profesional

Replanteamiento gráfico de los Exámenes de Evaluación Mensual del aula 4 Años del Nido Días Felices - distrito de San Miguel

Pérez Contreras, Gonzalo David 31 July 2021 (has links)
La coyuntura actual, así como en muchas otras instituciones, ha hecho que el “Aula 4 Años” de Nido “Días Felices - Villa Nova” de San Miguel, Lima, Perú, tenga que adaptarse a una nueva realidad, en la que deben dar clases virtuales y evaluar por el mismo medio. Esto ha traído en consecuencia problemas de comunicación entre los ejercicios que dictan las profesoras y lo desarrollado por los niños en las fichas sobre las que se los va a evaluar, haciendo más inexacto el resultado. La metodología actual dicta que los niños deben tener sus fichas de evaluación e ir resolviendo punto por punto mientras la profesora explica cada ejercicio mediante la videollamada de la clase. El primer problema surge cuando por motivos de señal de internet o por sonidos externos no se puede escuchar la indicación, por consiguiente, los niños y tutores quienes los acompañan pueden verse frustrados al no tener una instrucción visual lo suficientemente explícita en la ficha. Además, un segundo problema ocurre cuando el niño, por la percepción visual propia de su edad, confunde los objetivos de los ejercicios, esto también afectando su estado de ánimo y no dejando que se desenvuelva de forma autónoma. El objetivo del proyecto será reestructurar y rediseñar las fichas de evaluación, creando un recurso para las profesoras, que puedan usar en función de enfrentar estos y otros problemas propios de una falta de recursos, típico de una institución educativa de promedio económico. / The current situation, as well as in many other institutions, has made the “4 Years Classroom” of "Días Felices - Villa Nova" Kindergarten in San Miguel, Lima, Peru, have to adapt to a new reality, in which they must give virtual classes and evaluate by the same means. This has consequently brought communication problems between the instructions dictated by the teachers and what is developed by the children in the sheets on which they are going to be evaluated, making the result more inaccurate. The current methodology dictates that the children must have their evaluation sheets and solve them point by point while the teacher explains each exercise through the class video call. The first problem arises when due to internet signal or external sounds the indication cannot be heard, therefore, the children and tutors who accompany them may be frustrated by not having a sufficiently explicit visual instruction on the sheet. In addition, a second problem occurs when the child, due to the visual perception of his age, confuses the objectives of the exercises, this also affecting his mood and not allowing him to develop autonomously. The objective of the project will be to restructure and redesign the evaluation sheets, creating a resource for the teachers, which they can use in order to face these and other problems of a lack of resources, typical of an educational institution of economic average. / Trabajo de Suficiencia Profesional
