Collision prediction of a moving object within a virtual world

This paper provides a solution for predicting moving/moving and moving/static collisions of objects within a virtual environment. Feasible prediction in real-time virtual worlds can be obtained by encompassing moving objects within a sphere and static objects within a convex polygon. Fast solutions are then attainable by describing the movement of objects parametrically in time as a polynomial.

The virtual world of exercises and deterrence

Miliary Exercises, Command Post Exercises and War Games serve to test procedures, but in some forms also serve to signal ability to defend against aggression, or to intimidate neighbours with the threat of aggression. Some indicators suggest that the solidarity of NATO and the EU is decreasing, and with it a plausible nuclear deterrence posture. This article discusses whether recent exercises and TV war games make matters better or worse.

Building an Interactive, Three-dimensional Virtual World

The movement of graphics and audio programming towards three dimensions is to better simulate the way we experience our world. In this project I looked to use methods for coming closer to such simulation via realistic graphics and sound combined with a natural interface. I did most of my work on a Dell OptiPlex with an 800 MHz Pentium III processor and an NVIDlA GeForce 256 AGP Plus graphics accelerator -high end products in the consumer market as of April 2000. For graphics, I used OpenGL [1], an open·source, multi-platform set of graphics libraries that is relatively easy to use, coded in C . The basic engine I first put together was a system to place objects in a scene and to navigate around the scene in real time. Once I accomplished this, I was able to investigate specific techniques for making parts of a scene more appealing.

Language Learning in 3D Virtual World

Second Life (SL) is an ideal platform for language learning. It is called a Multi-User Virtual Environment, where users can have varieties of learning experiences in life-like environments. Numerous attempts have been made to use SL as a platform for language teaching and the possibility of SL as a means to promote conversational interactions has been reported. However, the research so far has largely focused on simply using SL without further augmentations for communication between learners or between teachers and learners in a school-like environment. Conversely, not enough attention has been paid to its controllability which builds on the embedded functions in SL. This study, based on the latest theories of second language acquisition, especially on the Task Based Language Teaching and the Interaction Hypothesis, proposes to design and implement an automatized interactive task space (AITS) where robotic agents work as interlocutors of learners. This paper presents a design that incorporates the SLA theories into SL and the implementation method of the design to construct AITS, fulfilling the controllability of SL. It also presents the result of the evaluation experiment conducted on the constructed AITS.

Utilizing the CORBA platform in the construction of a highly immersive virtual environment

This article presents the implementation of a distributed system of virtual reality, through the integration of services offered by the CORBA platform (Common Object Request Broker Architecture) and by the environment of development of 3D graphic applications in real time, the WorldToolkit, of Sense8. The developed application for the validation of this integration is that of a virtual city, with an emphasis on its traffic ways, vehicles (movable objects) and buildings (immovable objects). In this virtual world, several users can interact, each one controlling his/her own car. Since the modelling of the application took into consideration the criteria and principles of the Transport Engineering, the aim is to use it in the planning, project and construction of traffic ways for vehicles. The system was structured according to the approach client/server utilizing multicast communication among the participating nodes. The chosen implementation for the CORBA was the Iona's ORBIX software. The performance results obtained are presented and discussed in the end.

A bot spooler architecture to integrate virtual worlds with e-learning management systems for corporate training

Joining efforts of academic and corporate teams, we developed an integration architecture - MULTIS - that enables corporate e-learning managers to use a Learning Management System (LMS) for management of educational activities in virtual worlds. This architecture was then implemented for the Formare LMS. In this paper we present this architecture and concretizations of its implementation for the Second Life Grid/OpenSimulator virtual world platforms. Current systems are focused on activities managed by individual trainers, rather than groups of trainers and large numbers of trainees: they focus on providing the LMS with information about educational activities taking place in a virtual world and/or being able to access within the virtual world some of the information stored in the LMS, and disregard the streamlining of activity setup and data collection in multi-trainer contexts, among other administrative issues. This architecture aims to overcome the limitations of existing systems for organizational management of corporate e-learning activities.

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

Programa de gestió per la Boutique Shahrazad

Per tal d'iniciar el meu TFC, vaig decidir començar a desenvolupar un programa que contempla la gestió diària del comerç, així com la dels productes, clients, proveïdors, vendes i compres, d’un negoci que es tracta d’una botiga de roba, sabates,bosses i complements, per tal de convertir-ho en un sistema de gestió més complert. Actualment, l’entorn de negoci en el petit comerç està cada cop més desplaçat degut al gran creixement de les grans superfícies per part de franquícies de cadenes molt potents. A més, els clients són cada cop més exigents i el mercat està cada vegada més saturat. És per això que voldrem incloure un valor afegit al sistema, per poder donar un nou punt de vista al negoci, de tal manera que permeti nodrir la nostra relació amb el client, de manera que la col•laboració sigui satisfactòria per ambdues parts. I per acabar s’elabora una pàgina web per tal de fer promoció i publicitat per la botiga, ja que avui en dia és molt important existir en el món virtual.

LEVERAGING SANDBOX IMMERSIVE 3D VIRTUAL WORLDS TO DEVELOP DO-IT- YOURSELF TEACHING GAMES: IMPLEMENTATION TO MARKETING CASE STUDY TEACHING IN SECOND LIFE

Games are powerful and engaging. On average, one billion people spend at least 1 hour a day playing computer and videogames. This is even more true with the younger generations. Our students have become the < digital natives >, the < gamers >, the < virtual generation >. Research shows that those who are most at risk for failure in the traditional classroom setting, also spend more time than their counterparts, using video games. They might strive, given a different learning environment. Educators have the responsibility to align their teaching style to these younger generation learning styles. However, many academics resist the use of computer-assisted learning that has been "created elsewhere". This can be extrapolated to game-based teaching: even if educational games were more widely authored, their adoption would still be limited to the educators who feel a match between the authored games and their own beliefs and practices. Consequently, game-based teaching would be much more widespread if teachers could develop their own games, or at least customize them. Yet, the development and customization of teaching games are complex and costly. This research uses a design science methodology, leveraging gamification techniques, active and cooperative learning theories, as well as immersive sandbox 3D virtual worlds, to develop a method which allows management instructors to transform any off-the-shelf case study into an engaging collaborative gamified experience. This method is applied to marketing case studies, and uses the sandbox virtual world of Second Life. -- Les jeux sont puissants et motivants, En moyenne, un milliard de personnes passent au moins 1 heure par jour jouer à des jeux vidéo sur ordinateur. Ceci se vérifie encore plus avec les jeunes générations, Nos étudiants sont nés à l'ère du numérique, certains les appellent des < gamers >, d'autres la < génération virtuelle >. Les études montrent que les élèves qui se trouvent en échec scolaire dans les salles de classes traditionnelles, passent aussi plus de temps que leurs homologues à jouer à des jeux vidéo. lls pourraient potentiellement briller, si on leur proposait un autre environnement d'apprentissage. Les enseignants ont la responsabilité d'adapter leur style d'enseignement aux styles d'apprentissage de ces jeunes générations. Toutefois, de nombreux professeurs résistent lorsqu'il s'agit d'utiliser des contenus d'apprentissage assisté par ordinateur, développés par d'autres. Ceci peut être extrapolé à l'enseignement par les jeux : même si un plus grand nombre de jeux éducatifs était créé, leur adoption se limiterait tout de même aux éducateurs qui perçoivent une bonne adéquation entre ces jeux et leurs propres convictions et pratiques. Par conséquent, I'enseignement par les jeux serait bien plus répandu si les enseignants pouvaient développer leurs propres jeux, ou au moins les customiser. Mais le développement de jeux pédagogiques est complexe et coûteux. Cette recherche utilise une méthodologie Design Science pour développer, en s'appuyant sur des techniques de ludification, sur les théories de pédagogie active et d'apprentissage coopératif, ainsi que sur les mondes virtuels immersifs < bac à sable > en 3D, une méthode qui permet aux enseignants et formateurs de management, de transformer n'importe quelle étude de cas, provenant par exemple d'une centrale de cas, en une expérience ludique, collaborative et motivante. Cette méthode est appliquée aux études de cas Marketing dans le monde virtuel de Second Life.

Reporting customer information for sales management

Elektroniikan alihankintapalveluiden (EMS) liiketoimintaympäristössä yritykset toimivat pääasiassa asiakkaiden projektien ja ulkoistamispäätösten keskellä. Tämän tyyppisessä liiketoimintaympäristössä on asiakas keskeisessä roolissa, kuten liiketoiminnassa yleensäkin. Termi EMS sisältää koko tuotteen elinkaaren aina suunnittelusta myynnin jälkeisiin palveluihin. Asiakkaan olessa erittäin tärkeä yritykselle, on myös selvitettävä mitkä asiakkaat ovat yrityksen kannalta arvokkaimmat. Tämän tutkimuksen tavoitteena oli selvittää myyntijohdon tietotarpeet sekä löytää selkeä ja helppokäyttöinen tapa tuoda tarvittava informaatio heidän käyttöönsä. Tietotarpeet selvitettiin haastatteluilla ja kyselytutkimuksella ja sopivan järjestelmän löytämisessä käytettiin prototyyppi-lähestymistä, jotta saataisiin selville täyttääkö valittu järjestelmä myyntijohdon tarpeet. Nk. dashboard-mittaristot ovat hyvä tapa tuoda asiakasinformaatiota päätöksenteontueksi. Tälläisillä mittaristoilla voidaan myös yhdistellä eri lähteistä olevaa tietoa ja tuoda se ymmärrettävässä muodossa esiin. Tässä tutkimuksessa kuvataan mittariston suunnittelu myyntijohdon tarpeisiin. Ensimmäisenä tutkitaan kyselyn avulla myyntijohtajien tiedon tarpeet ja tämän jälkeen etsitään sopiva tekninen sovellus ja ratkaistaan tiedon siirtoihin liittyvät ongelmat. Kun ensimmäinen versio on valmis, esitellään se myyntijohdolle, jotta saadaan kerättyä kommentit seuraavaan versioon.
