A virtual environment for the assessment and the rehabilitation of the visuo-constructional ability in dementia patients

This study proposes a VE that offers a reliable diagnosis of the stage of cognitive decline in dementia patients and assists the delay of this decline in terms of the visuo-constructional ability. The proposed VE, in the case of the assessment, presents a visuo-constructional completion task, which requires spatial perception, motor memory and the perception of the target object. In the case of the rehabilitation the VE uses sound as audio-feedback that, with the aid of the music perception, tends to develop an enhancement in the visuo-construction ability of the dementia patients that can be generalized even outside of the VE. The study examined 30 subjects that were normal controls (N), 30 patients suffering from memory disorders (Age-Associated Memory Impairment--AAMI) and 30 suffering from Alzheimer's Disease (AD). The results showed that there is a significant correlation between the performance in the visuo-constructional task and the dementia diagnosis. It also seems that the visuo-constructional ability of the (AD) patients can be statistically improved by the audio experience in the VE. The empirical results of this study offer an alternative diagnosis and treatment of dementia patients and could share some light in the brain sub-systems that are responsible for the visuo-constructional ability. Further studies are required in order to investigate the nature of this phenomenon more.

The design and evaluation of distributed virtual environment to support learning in global operations management

The primary goal of this research is to design and develop an education technology to support learning in global operations management. The research implements a series of studies to determine the right balance among user requirements, learning methods and applied technologies, on a view of student-centred learning. This research is multidisciplinary by nature, involving topics from various disciplines such as global operations management, curriculum and contemporary learning theory, and computer aided learning. Innovative learning models that emphasise on technological implementation are employed and discussed throughout this research.

Novel Virtual Environment for Alternative Treatment of Children with Cerebral Palsy

Cerebral palsy is a severe condition usually caused by decreased brain oxygenation during pregnancy, at birth or soon after birth. Conventional treatments for cerebral palsy are often tiresome and expensive, leading patients to quit treatment. In this paper, we describe a virtual environment for patients to engage in a playful therapeutic game for neuropsychomotor rehabilitation, based on the experience of the occupational therapy program of the Nucleus for Integrated Medical Assistance (NAMI) at the University of Fortaleza, Brazil. Integration between patient and virtual environment occurs through the hand motion sensor “Leap Motion,” plus the electroencephalographic sensor “MindWave,” responsible for measuring attention levels during task execution. To evaluate the virtual environment, eight clinical experts on cerebral palsy were subjected to a questionnaire regarding the potential of the experimental virtual environment to promote cognitive and motor rehabilitation, as well as the potential of the treatment to enhance risks and/or negatively influence the patient’s development. Based on the very positive appraisal of the experts, we propose that the experimental virtual environment is a promising alternative tool for the rehabilitation of children with cerebral palsy.

Participatory design in the project of virtual learning environment of histology

This present article describes a research on the development, under the approach of participatory design, a virtual teaching-learning of Histology in which students and teachers participated actively in all stages of development of the educational environment. We postulates that the development of virtual learning environment of Histology, through the Participatory Design approach, contributes to greater acceptance and use by students and that the adoption of virtual environment for teaching and learning by teachers is a determining factor of use by students

On a Virtual Learning Environment

Education in the Information Society is based on asynchronism in time and space, interactivity and virtual restructuring of the educational space. One way to implement such a model of training is web-based - use of the WWW as a virtual environment to access educational materials or to organize the learning process. This work presents a virtual learning environment (VLE) developed for students and made up of modules of dynamically changing content implemented by authorized users. The aim is, through advanced technology for e-learning, testing and self-testing to stimulate students’ activity to focus their potential on the acquisition of the necessary knowledge, skills and competences. The VLE was developed under the Human Resources Development Operational Programme.

Tratamiento psicológico del dolor através de entornos de realidad virtual

Proyecto de investigación de una estancia en el Università degli Studi de Padova, Italia, durante noviembre del 2007. El objetivo principal ha sido desarrollar entornos de realidad virtual para el tratamiento del dolor agudo mejorando las propiedades gráficas de los mundos virtuales. La participación en las diferentes líneas de Investigación en el laboratorio de tecnología humana ha permitido la aplicación de nuevas tecnologías en el estudio del dolor.

Bibliotecas y centros de documentación en un entorno virtual

Les Biblioteques i Centres de Documentació han exercit sempre un paper important en el desenvolupament de l'aprenentatge, de la docència i de la investigació, però el canvi que s'ha experimentat i s'està experimentant en el camp docent en aquests últims anys, ha potenciat molt més la funció d'aquest tipus de centres, convertint-los en eixos bàsics del sistema educatiu, passant a formar part, en molts casos, del model dissenyat per exercir la funció educativa i investigadora a través d'un entorn virtual.
