An Application of Augmented Reality (AR) in the Teaching of an Arc Welding Robot

Augmented Reality (AR) is an emerging technology that utilizes computer vision methods to overlay virtual objects onto the real world scene so as to make them appear to co-exist with the real objects. Its main objective is to enhance the user’s interaction with the real world by providing the right information needed to perform a certain task. Applications of this technology in manufacturing include maintenance, assembly and telerobotics. In this paper, we explore the potential of teaching a robot to perform an arc welding task in an AR environment. We present the motivation, features of a system using the popular ARToolkit package, and a discussion on the issues and implications of our research.

Assembly Design and Evaluation in an Augmented Reality Environment

The technologies and methodologies of assembly design and evaluation in the early design stage are highly significant to product development. This paper looks at a promising technology to mix real components (e.g. physical prototypes, assembly tools, machines, etc.) with virtual components to create an Augmented Reality (AR) interface for assembly process evaluation. The goal of this paper is to clarify the methodologies and enabling technologies of how to establish an AR assembly simulation and evaluation environment. The architecture of an AR assembly system is proposed and the important functional modules including AR environment set-up, design for assembly (DFA) analysis and AR assembly sequence planning in an AR environment are discussed in detail.

A distributed environment for virtual and/or real experiments for underwater robots

This paper presents the distributed environment for virtual and/or real experiments for underwater robots (DEVRE). This environment is composed of a set of processes running on a local area network composed of three sites: 1) the onboard AUV computer; 2) a surface computer used as human-machine interface (HMI); and 3) a computer used for simulating the vehicle dynamics and representing the virtual world. The HMI can be transparently linked to the real sensors and actuators dealing with a real mission. It can also be linked with virtual sensors and virtual actuators, dealing with a virtual mission. The aim of DEVRE is to assist engineers during the software development and testing in the lab prior to real experiments

Efectos de la crisis económica europea en el panorama migratorio colombiano. Estudio de caso: migración laboral española en Colombia (2008-2013)

Actualmente, Colombia se encuentra inserta en dinámicas migratorias internacionales, no sólo como país expulsor de estos flujos, sino como destino y país de tránsito; la transformación que ha tenido el panorama migratorio colombiano es reciente y obedece a múltiples factores de carácter interno y externo. El fortalecimiento de la economía colombiana y la coyuntura de la crisis económica española han creado un ambiente propicio para la llegada de una migración laboral altamente calificada proveniente de España. Esta situación no sólo ha configurado al país por primera vez como un destino migratorio, sino ha puesto en evidencia la necesidad de una política migratoria eficaz y capaz de enfrentar los desafíos que impone la nueva realidad migratoria.

Technology enhanced learning and augmented reality : an application on multimedia interactive books

Multimedia Interactive Book (miBook) reflects the development of a new concept of virtual interpretation of traditional text books and audio-visual content. By encompassing new technological approaches, using augmented reality technology, allows the final user to experience a variety of sensorial stimuli while enjoying and interacting with the content; therefore enhancing the learning process. miBook stands for a global educational intention to enable people not only to access but also to appropriate intellectually valuable contents coming from different linguistic and cultural contexts.

Cozinha Virtual : uma prova de avaliação Neuropsicológica em Realidade Virtual

Esta dissertação surgiu com o intuito de criar uma prova neuropsicológica com todas as características das tradicionais provas de papel e lápis, com o acréscimo de vantagens que as novas tecnologias lhe podem trazer. Desta forma, desenvolveu-se um ambiente virtual com um propósito avaliativo, semelhante ao da prova em papel Trail Making Test e posteriormente ao seu desenvolvimento elaborou-se uma aplicação que foi testada em dois grupos. Compostas por um total de 47 elementos, estas amostras abrangeram população com e sem diagnóstico de problemas de alcoolismo (Síndrome de Dependência Alcoólica), que foram submetidas à execução das provas Cozinha Virtual e Trail Making Test. Os dados daí resultantes comprovam a capacidade desta prova avaliar os défices cognitivos ao nível da flexibilidade cognitiva, da capacidade de sequenciação, de procura visual, velocidade motora e capacidades atencionais e confirmam também a sua correlação com a prova que lhe deu origem.

Proyecto de factibilidad: creación de un canal alternativo virtual para la comercialización electrónica de productos de computación de la empresa Wirelessoft.

Esta tesis de maestría fue desarrollada con el objeto de analizar la factibilidad de creación de un canal alternativo virtual para la comercialización electrónica de productos de computación, específicamente de la empresa Wirelessoft, que es una empresa nacional de tipo familiar, cuya línea de negocios comprende la prestación de soluciones tecnológicas en el campo de la seguridad electrónica y la comercialización de productos de computación. Para determinar la factibilidad del proyecto, fue necesario en primer lugar, efectuar una descripción de los fundamentos teóricos del comercio electrónico, sus conceptos, tipos, estadísticas, y la normativa legal en la cual se sustenta a nivel nacional e internacional. En forma posterior y con el conocimiento previo sobre los fundamentos del comercio electrónico, se procedió a desarrollar el análisis de factibilidad considerando cinco tipos de enfoque: Comercial, Técnico, Operacional, Legal, y Financiero, los cuales permitieron en su conjunto, establecer los requerimientos de la empresa para ejecutar el proyecto, concluir que el mismo sí es viable en términos financieros (valor actual neto positivo y una tasa interna de retorno mayor al costo de oportunidad), y emitir recomendaciones a la empresa para su ejecución.

As David Cameron prepares to deliver his momentous “Europe” speech, Adam Łazowski warns the British Prime Minister that a divorce from the EU will not be easy and that the decision should be based on a very thorough political, economic and legal analysis, as the consequences in all possible respects will be profound.

Dynamic virtual environments using really simple syndication

This paper investigates the use of really simple syndication (RSS) to dynamically change virtual environments. The case study presented here uses meteorological data downloaded from the Internet in the form of an RSS feed, this data is used to simulate current weather patterns in a virtual environment. The downloaded data is aggregated and interpreted in conjunction with a configuration file, used to associate relevant weather information to the rendering engine. The engine is able to animate a wide range of basic weather patterns. Virtual reality is a way of immersing a user into a different environment, the amount of immersion the user experiences is important. Collaborative virtual reality will benefit from this work by gaining a simple way to incorporate up-to-date RSS feed data into any environment scenario. Instead of simulating weather conditions in training scenarios, actual weather conditions can be incorporated, improving the scenario and immersion.

Navigation assistance for wayfinding in the virtual environments: taxonomy and a survey

Efficient Navigation is essential for the user-acceptance of the Virtual Environments (VEs), but it is also inherently, a difficult task to perform. Resulting research in the area provides users with great variety of navigation assistance in VEs however it is still known to be inadequate, complex and suffers through many limitations. In this paper we discuss the task of navigation in the virtual environments and record the wayfinding assistance currently available for the VEs. The paper introduces taxonomy of navigation and categorizes the aids on basis of the functions performed. The paper provides views on current work performed in the area of non-speech auditory aids. Further we conclude by providing views on the important areas that require further investigation and research.
