The influence of organisational facilitating conditions and technology acceptance factors on the effectiveness of virtual communities of practice
2019
The present study aimed to examine the influence of facilitating conditions on the effectiveness of a Virtual Community of Practice. To do so, we first analysed the influence of facilitating condit...
Virtual Reality and Psychopathology
2009
Progress in the development of Virtual Reality (VR) is faster than has been forecast, which makes deep reflection on its potential uses and abuses absolutely necessary. The current article focuses on the analysis of some of the applications and implications of VR on psychopathology. It is obvious that they could be many, but we are only focusing on: (a) VR as a model to answer some central questions that traditionally have intrigued psychopathologists; and (b) VR and possible psychopathological experiences. We believe that VR has the potential of becoming a tool that will allow psychopathology to challenge and modify theoretical positions already established, and to pose new ones. This new …
A new user interface for human-computer interaction in virtual reality environments
2010
This paper concerns the result of a research activity about the problems related to the human-computer interaction (both hardware and software) in virtual reality systems. In particular, a virtual reality application package, called VIRDE and used for the design review in immersive environment, has been used as a case study. After a detailed analysis of the hardware and software systems, and the examination of the main functional requirements, a new user interface has been developed. This new interface being composed of two input devices (tracked by an optical system) permits the two-hands interaction, instead of the most commonly single-hand interaction. The measurement of the software usa…
To Move or Not to Move?
2019
This chapter deals with the problem of including motion cues in VR applications. From the challenges of this technology to the latest trends in the field, the authors discuss the benefits and problems of including these particular perceptual cues. First, readers will know how motion cues are usually generated in simulators and VR applications in general. Then, the authors list the major problems of this process and the reasons why its development has not followed the pace of the rest of VR elements (mainly the display technology), reviewing the motion vs. no-motion question from several perspectives. The general answer to this discussion is that motion cues are necessary in VR applications—…
Translating and Networking in Virtual Learning Environments
2018
The chapter describes the experience of three projects carried out at the University of Latvia and their contribution to developing student skills for working in virtual networks. The research is carried out against the background of the rise of a community-based model in translation and increased involvement of virtual networks of translators in solving translation problems and the discussion of broader issues of the profession. The chapter describes the three projects, provides the approach and rationale for their development, dwells on problems faced in the projects and their solutions, as well as shares the lessons learned and recommendations for those who are interested in similar proj…
Computer Mediated Communication and Collaboration in a Virtual Learning Environment Based on a Multi-agent System with Wasp-Like Behavior
2008
In this paper is presented a model for an adaptive multi-agent system for dynamic routing of the grants' activities from a learning environment, based on the adaptive wasp colonies behavior. The agents use wasp task allocation behavior, combined with a model of wasp dominance hierarchy formation. The model we introduced allows the assignment of activities in a grant, taking into account the specialization of students, their experience and the complexity of activities already taken. An adaptive method allows students to enter in the Grant system for the first time. The system is changing dynamic, because both the type of activities and the students involved in the system change. Our approach…
From medical data to simple virtual mock-up of scapulo-humeral joint
2008
The surgical operations of shoulder joint are guided by various principles: osteosynthesis in the case of fracture, osteotomy in order to correct a deformation or to modify the functioning of the joint, or implementation of articular prosthesis. At the end of the twentieth century, many innovations in the domains of biomechanics and orthopedic surgery have been performed. Nevertheless, theoretical and practical problems may appear during the operation (visual field of surgeon is very limited, quality and shape of the bone is variable depending on the patient). Biomechanical criteria of success are defined for each intervention. For example, the installation with success of prosthetic implan…
The impact of Information Technology on the identification of species and archiviation of taxonomic and floristic data.
2007
In plant taxonomy, classification aims at reconstructing an evolutionary history, usually represented by means of phylogenetic trees. The approach followed by the classification is hierarchical, and rather in coherence with the dichotomies traditionally used for identifying a certain species. But classification and identification are different, since the latter just aims at finding the name of a specimen, eventually in order to get information on it. There are many ways to identify a specimen: to trace it back to its origin, by following the bifurcations of its phylogenetic tree is one possibility, but not always the easiest and quickest one. This theme has been touched during the symposium…
Estudio de variables de responsabilidad social universitaria
2010
El estudio de la Responsabilidad Social Universitaria (RSU) implica la investigación sobre las variables psicológicas que intervienen en la adquisición y desarrollo de comportamientos socialmente responsables por parte del alumnado, como finalidad de la educación superior de formar a personas responsables, procurando que la educación cívica en la juventud universitaria tenga un impacto en las futuras generaciones de profesionales. Este estudio ha identificado como variables psicológicas en las cuales tener presente el impacto de la formación universitaria, los valores humanos, según adquieran orientación a la auto-promoción o a la auto-trascendencia, y el efecto de la empatía como mediadora…
La Sociedad de las turbas, la sociedad de la incomunicación
2023
En los últimos 20 años, a medida que se ha desarrollado la sociedad de la información, también ha sido tendencia olvidar a los referentes que ayudaron a comprender la mass communication society. Se ha producido un vaciamiento conceptual que debemos enmendar para problematizar los discursos del odio, la polarización y la fractura de la ex- periencia entre lo real y lo virtual. Para ello, en este ensayo partimos de una recopilación bibliográfica constructivis- ta que conecta las industrias culturales, como entidades productoras de consensos; los medios de comunicación, como instituciones de socialización colectiva; el proceso de virtualización digital, como ruptura con la experiencia no media…
