1. Mobile Augmented Reality enhances indoor navigation for wheelchair users
Introduction: Individuals with mobility impairments associated with lower limb disabilities often face enormous challenges to participate in routine activities and to move around various environments. For many, the use of wheelchairs is paramount to provide mobility and social inclusion. Nevertheless, they still face a number of challenges to properly functi

2. Razonamiento Estadístico de Estudiantes Universitarios sobre el Análisis de Datos en un Ambiente Computacional
In this article, research results are presented for a sample of 34 university students (18-19 years) about statistical reasoning developed to analyze data through an exploratory approach in a computational environment characterized by the availability of various dynamic and interactive representations (graphical, numerical, and symbolic). The results show th

3. Acionamento de dispositivos robóticos através de interface natural em realidade aumentada / Robotic device actuation through natural interface in augmented reality
Since the beginning of History and particularly of the Industrial Revolution, human beings have sought to replace or supplement their workforce with devices and machines, in order to expand their productive capacity or to solve tasks for which the use of human power is not satisfactory or it is dangerous. This need pushed the development of robotic devices i

4. O ritual e os símbolos: a realização dos grafismos rupestres na região do município de Camalaú (PB)
This work aims to infer the relationship between the realm of myth with the production of rock graphics, ie, whether the production of these graphics are rituals linked to a mythic structure whatever, being able to express a sacred dimension. Through authors such as Eliade (1991, 1983, 2007, 2008 a, 2008 b), Leroi-Gourhan (2007), Levi-Strauss (1996, 2007, 20

5. Constant Boundary Elements on graphics hardware: a GPU-CPU complementary implementation
Numerical simulation of engineering problems has reached such a large scale that the use of a parallel computing approach is required to obtain solutions within a reasonable time. Recent efforts have been made to implement these large scale computational tasks on general-purpose programmable graphics hardware (GPGPU). The Graphics Processing Unit (GPU) is sp

6. Capture and 3D modeling of hands with motion tracking / Captura e modelagem 3D de mãos com rastreamento de movimentos
Currently, general-purpose computers come equipped with webcams cameras of good resolution and high-speed, which enables a visually user interaction, through gestures, with software applications. This allows a greater sense of reality in interactive processes of virtual and augmented reality. The goal of this research is to capture and compose 3D model of ha

7. Arquitetura como interface para a informação: sobre a espacialização das tecnologias da informação rumo a práticas colaborativas
This study examines an intersection between the spatialization of information and CSCW - Computer Supported Collaborative Work. More specifically it is argued the possibility of influence of the spatial distribution of ICT (information and communication technologies) on the interactions between members of two remotely connected laboratories. Spatialization (

8. Análise de imagens tomográficas da Ciência do Solo em ambiente de realidade virtual
This work presents a Virtual Reality environment dedicated to the analysis of tomographic images of Soil Science. Its architecture uses models proceeding from a volumetric (3-D) reconstruction algorithm, summed with several graphics processes of manipulation and visualization, in a way to provide immersion and interaction of the user with the virtual scene.

9. Textos Multimodais e Letramento: habilidades na leitura de gráficos da Folha de São Paulo por um grupo de alunos do ensino médio
The growing presence of the image in verbal communication, especially in the media, raised the interest for multimodal texts, such as the graphic for the object of study. Despite the little attention which linguistic studies give to this textual genre, I searched for references in psychology in relation to mathematical education, and consequently found out t

10. Upper and middle Sapucaí: scenarios for the environmental planning / Alto e médio Sapucai: cenários para o planejamento ambiental
The application about the characteristics of Sapucai´s Hydrographic Basin, in Minas Gerais permitted to understand that this region, rich in human potential and natural, must be viewed as strategic, for his hydro and landscape potential, for his cultural riches and for his proximity of the most metropolitan regions of the country. However, the development m

11. A methodology for development augmented reality applications using mobile phones and sensors devices. / Uma metodologia para o desenvolvimento de aplicações de realidade aumentada em telefones celulares utilizando dispositivos sensores.
Handheld Augmented Reality or Handheld AR is the implementation of Augmented Reality (AR) systems into handheld devices. Handheld AR applications use the handheld devices camera to recognize markers (inserted into the environment). This process enables data entry into AR system. The response generated for these applications are presented as virtual images (3

12. A visualização na resolução de problemas de calculo diferencial e integral no ambiente computacional MPP / Visual aspects of solving problem in calculus within an MPP computational environment
Rarely brazilian universities study computational tool to teach of Calculus. However, in countries like United Kingdom, United States of America, Germany, Mexico, Spain, Colombia and Venezuela, these studies are very advanced, showing includes assessments about of these technologies (graphical and numerical calculators, videos and software) in the undergradu
