‘Geoliteracia’, ‘cartologia’, desenvolvimento cognitivo e um jogo móvel

Some researches in education science develop educative games on mobile devices for letting elementary school students play outdoor to learn geographic facts, concepts, and patterns. The challenge is about improving their geographic literacy and fluency, or ‘geoliteracy’, and their map-reading competencies, called cartology, before adolescence. There a critical stumbling ‘threshold’ can impede their geospatial cognitive development, which result in a majority of adults being not geographically literate neither efficient, in real-life context, for reading and using maps. Designing a mobile educative serious game implies applying conceptual and pragmatic methods for both learning and teaching geospatial competencies accordingly to school curriculum. The theoretical framework presented links maps to cartographical semiology, the children’s cognitive development stages for geospatial representation, and an experiential learning cycle model. The latter sequentially supports three main cartographic processes of map-making: reflexive visualization, and map-reading, which sustain any geographical reasoning. The mobile game proposed combines components of increasing complexity where the map plays the main role in the course of different activities: scenarios of typical “rounds” and rules of the game within local terrain; types of geometrical and geospatial trajectories to trace and follow while playing; and specific themes relevant to school subjects. Thus, geographical discussions stop worrying about where, to worry about the reason of situations and the occurrence of phenomena.Algunas investigaciones en ciencias de la educación desarrollan juegos educativos en dispositivos móviles para incentivar el aprendizaje de hechos, conceptos y modelos geográficos en estudiantes de escuelas primarias. El desafío consiste en mejorar su alfabetización y fluidez geográfica, o geoalfabetización, y sus competencias en lectura de mapas antes de la adolescencia, sintetizadas aquí bajo la denominación de cartología, la cual parece ser un umbral crítico que obstruye el desarrollo cognitivo geoespacial de los adultos. Diseñar un juego educativo móvil implica integrar métodos conceptuales y prácticos para la enseñanza y aprendizaje de las competencias geoespaciales, conforme al currículo escolar. El marco teórico que se presenta vincula los mapas con la semiología cartográfica, las etapas de desarrollo cognitivo del niño referentes a la representación del espacio geográfico y el ciclo de aprendizaje experiencial. Este último supone una serie de procesos cartográficos esenciales que sirven de base a cualquier análisis o razonamiento geográfico: creación de mapas, visualización reflexiva y lectura cartográfica. El juego que se propone conjuga componentes de creciente complejidad en los cuales el mapa es protagonista en el transcurso de diferentes actividades: rondas típicas con reglas particulares sobre terrenos determinados; trayectorias geométricas y geoespaciales por trazar y seguir durante el juego; temas específicos relacionados con las asignaturas escolares y con los objetivos propuestos por los maestros, etc. Así, las discusiones geográficas dejan de preocuparse por el dónde para inquietarse por el porqué de las situaciones y el acontecer de los fenómenos.Algumas pesquisas nas ciências da educação desenvolvem jogos educativos para dispositivos móveis através dos quais alunos da escola primária aprendem fatos, conceitos e modelos geográficos brincando ao ar livre. O desafio é melhorar a literacia e a fluência geográfica desses alunos, ou sua ‘geoliteracia’, e suas competências para ler mapas, a chamada ‘cartologia’, antes da adolescência, quando surge um limiar crítico que pode impedir o desenvolvimento cognitivo geoespacial das crianças. A maioria de adultos não são geograficamente letrados nem eficientes para ler e usar mapas. Conceber um jogo educativo móvel integra métodos conceituais e práticos para o ensino e a aprendizagem das competências geoespaciais, conforme o currículo escolar. O quadro teórico apresentado conecta os mapas à semiologia cartográfica, os estágios de desenvolvimento cognitivo das crianças no que se refere às representações do espaço geográfico e o ciclo de aprendizagem experiencial. Este último supõem uma sequência de três processos cartográficos principais que servem de base a qualquer raciocínio geográfico: criação de mapas, visualização reflexiva e leitura de mapas. O jogo que é proposto combina componentes de complexidade crescente onde o mapa é o protagonista no decorrer de diferentes atividades: cenários com ‘rondadas’ e regras típicas do jogo num determinado terreno; tipos de trajetórias geométricas e geoespaciais a serem traçadas e seguidas durante o jogo; temas específicos pertinentes aos assuntos escolares. Assim, as discussões geográficas deixam de se preocupar sobre onde para questionar a razão das situações e a ocorrência dos fenômenos

GIS Spatial Analysis for the Design of Urban Open Space

Urban design in the landscape tradition has a unique set of users and uses due to the nature of urban sites in densely developed areas, yet many urban designers employ the same basic approach in terms of their design process and site analysis methods as they would in suburban or rural areas. In addition, urban design theory is not adequately reflected in the analytical methods traditionally used by landscape architects, nor do traditional methods adequately synthesize the multitude of complex information urban designers must consider throughout all phases of the urban design process. However, GIS offers unique tools for data management, visualization and most importantly spatial analysis, allowing the urban designer new methods for the design of urban open space. The author examines the traditional site design process and site analysis methods, the most common GIS spatial analysis techniques, and the theoretical framework of urban design in the landscape architectural tradition in an effort to determine the applicability of GIS functionality as a resource to the traditional design process, determine the applicability of GIS spatial analysis tools to aid and enhance the traditional site analysis methods, and determine the applicability of GIS spatial analysis tools as a means to analyze the key dimensions of urban design as set forth by urban design theory. GIS spatial analysis tools are demonstrated following the traditional design process in an application study at Republic Square, an urban park in Austin, Texas.Waller Creek Working Grou

Beyond visualization : designing interfaces to contextualize geospatial data

Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (p. 71-74).The growing sensor data collections about our environment have the potential to drastically change our perception of the fragile world we live in. To make sense of such data, we commonly use visualization techniques, enabling public discourse and analysis. This thesis describes the design and implementation of a series of interactive systems that integrate geospatial sensor data visualization and terrain models with various user interface modalities in an educational context to support data analysis and knowledge building using part-digital, part-physical rendering. The main contribution of this thesis is a concrete application scenario and initial prototype of a "Designed Environment" where we can explore the relationship between the surface of Japan's islands, the tension that originates in the fault lines along the seafloor beneath its east coast, and the resulting natural disasters. The system is able to import geospatial data from a multitude of sources on the "Spatial Web", bringing us one step closer to a tangible "dashboard of the Earth."Samuel Luescher.S.M

Interactive inspection of complex multi-object industrial assemblies

The final publication is available at Springer via http://dx.doi.org/10.1016/j.cad.2016.06.005The use of virtual prototypes and digital models containing thousands of individual objects is commonplace in complex industrial applications like the cooperative design of huge ships. Designers are interested in selecting and editing specific sets of objects during the interactive inspection sessions. This is however not supported by standard visualization systems for huge models. In this paper we discuss in detail the concept of rendering front in multiresolution trees, their properties and the algorithms that construct the hierarchy and efficiently render it, applied to very complex CAD models, so that the model structure and the identities of objects are preserved. We also propose an algorithm for the interactive inspection of huge models which uses a rendering budget and supports selection of individual objects and sets of objects, displacement of the selected objects and real-time collision detection during these displacements. Our solution–based on the analysis of several existing view-dependent visualization schemes–uses a Hybrid Multiresolution Tree that mixes layers of exact geometry, simplified models and impostors, together with a time-critical, view-dependent algorithm and a Constrained Front. The algorithm has been successfully tested in real industrial environments; the models involved are presented and discussed in the paper.Peer ReviewedPostprint (author's final draft

An Architecture for Online Affordance-based Perception and Whole-body Planning

The DARPA Robotics Challenge Trials held in December 2013 provided a landmark demonstration of dexterous mobile robots executing a variety of tasks aided by a remote human operator using only data from the robot's sensor suite transmitted over a constrained, field-realistic communications link. We describe the design considerations, architecture, implementation and performance of the software that Team MIT developed to command and control an Atlas humanoid robot. Our design emphasized human interaction with an efficient motion planner, where operators expressed desired robot actions in terms of affordances fit using perception and manipulated in a custom user interface. We highlight several important lessons we learned while developing our system on a highly compressed schedule

Creation of a GIS Based Model for Determining the Suitability of Implementing Green Infrastructure: In The Town Of Berlin Maryland

This project is entitled “Incorporation of Green Infrastructure Into Comprehensive Storm Water Management and the Effective Utilization of LiDAR: In the Town of Berlin ”. The goal of this research was the creation of a Geographic Information System (GIS) based model for determining the suitability / feasibility of green infrastructure implementation, as defined by this study, within the study area. This model was only applicable for the identified elements or tools under green infrastructure as defined by this study. This enabled clear and concise definitions and more readily identified the criteria and their parameters. The scope of the model’s applicability is limited to municipal level or larger scales with the data and nature of the analysis being unsuited for site level analysis. The model was successful in determining the areas of probable suitability for green infrastructure implementation. It was found that the study area on average had a medium to high potential for green infrastructure implementation. The model and its resulting products led to implications for better incorporation of green infrastructure into planning. The model also represented an excellent tool for education of the general public on green infrastructure, its concepts, implementation, and potential for debunking myths on its drawbacks. The model also allowed easier adaptation for the municipality and for other similar communities wishing to implement comparable policies. Advisor: Yunwoo Na

Towards Designing a Planet Walk Simulation in a Controlled Environment

Planet Walk Simulation involves several parametric readings like physical human body conditions, geographic and atmospheric conditions, etc. In this work, we have set goals including system state monitoring, terrain mapping, and user navigation. Specific objectives are displaying the user’s telemetry, elevating their spatial awareness through short range object detection, and displaying their location relative to origin using wi-fi routers. The experimental results showed navigation motion paths for astronauts and identify obstacles in the path with the help of LiDAR and Hololens
