Mondi virtuali e realtà virtuale. Un’analisi del fenomeno nella formazione sanitaria

2019

Negli ultimi sei anni la realtà virtuale (VR) e i mondi virtuali (VE) sono diventati sempre più tecnologicamente avanzati e molto più accessibili per quel che riguarda l’accesso economico. In sanità essi vengono utilizzati principalmente per cinque scopi: formazione degli studenti; formazione dei professionisti (simulatori); riabilitazione/terapia; cura/diagnosi e gestione del dolore. In questa review abbiamo analizzato 2.252 articoli pubblicati tra il 2012 e il 2019 su PubMed ed abbiamo organizzato gli articoli nelle aree simulazione per studenti; simulazione per specializzandi; simulazione avanzata per professionisti; applicazioni nei campi medico/dentale/infermieristico (soft skills); re…

Contribution of vibrational modalities for navigation in virtual environments

2016

The virtual environment navigation may induces the simulator sickness depending on conditions and user’s profile. The potential virtual reality multimodality may provide solutions to these problems while improving the sense of presence. In this context, the objective of this research is to determine what is the impact of vibrational modalities for navigation in virtual environments on the simulation.A taxonomy of navigation methods is proposed. It results in 4 types, specific egocentric, specific exocentric, abstract egocentric and abstract exocentric. First we simulate rumble strip vibrations during a driving simulation. The experimentation exposed that these vibrations make driver more aw…

Simulation and visualization of thermal metaphors in a virtual environment for thermal building assessment

2014

International audience; The current application of the design process through energy efficiency in virtual reality (VR) systems is limited mostly to building performance predictions and design review, as the issue of the data formats and the workflow used for 3D modeling, thermal calculation and VR visualization. The importance of energy efficiency and integration of advances in building design and VR technology have lead this research to focus on thermal simulation results visualized in a virtual environment to optimize building design, particularly concerning heritage buildings. The emphasis is on the perception of thermal data of a room simulated in a virtual environment (VE) in order to…

Contribution of virtual reality to functional rehabilitation

2010

Virtual reality has grown immensely. Practical applications for the use of this technology encompass many fields in both engineering science and human science. In the field of medicine, one of the newest fields to benefit from the advances in VR technology, virtual reality has become a major new therapeutic tool not only in medicine and surgery but also for the treatment of psychological disorders and rehabilitation for impaired person. Our research presented in this thesis aims at developing utilities to aid in functional rehabilitation using virtual reality technology. The main research question of our work concerns the effect of virtual metaphors in learning and training human gestures f…

The Effects of the Use of Serious Game in Eco-Driving Training

2016

International audience; Serious games present a promising approach to training and learning. The player is engaged in a virtual environment for a purpose beyond pure entertainment, all while having fun. In this paper, we investigate the effects of the use of serious game in eco-driving training. An approach has been developed in order to improve players’ practical skills in terms of eco-driving. This approach is based on the development of a driving simulation based on a serious game, integrating a multisensorial guidance system with metaphors including visual messages (information on fuel consumption, ideal speed area, gearbox management, etc.) and sounds (spatialized sounds, voice message…

Immersion revisited:A review of existing definitions of immersion and their relation to different theories of presence

2016

The term immersion continues to be applied inconsistently within and across different fields of research connected with the study of virtual reality and interactive media. Moreover, immersion is oftentimes used interchangeably with the terms presence and engagement. This article details a review of existing definitions of immersion originating within the study of video games, virtual environments, and literary works of fiction. Based on this review, a three-dimensional taxonomy of the various conceptualizations of immersion is proposed. That is, the existing definitions of immersion may be broadly divided into three categories, each representing a dimension of the taxonomy: immersion as a p…

Benefits of learning technologies in medical training, from full-scale simulators to virtual reality and multimedia presentations

2010

The rapid growth of technology provides a wide range of new learning tools such as multimedia presentations of materials, interactive animated images for anatomy learning, 3-D models, full-scale (FS) patient simulators, and microworld training software, which are virtual reality tools that include high-level interactive haptic properties. These new learning approaches have been recently used in medical training and education.

Evaluating the Authenticity of Virtual Environments: Comparison of Three Devices

2016

Immersive virtual environments (VEs) have the potential to provide novel cost effective ways for evaluating not only new environments and usability scenarios, but also potential user experiences. To achieve this, VEs must be adequately realistic. The level of perceived authenticity can be ascertained by measuring the levels of immersion people experience in their VE interactions. In this paper the degree of authenticity is measured via anauthenticity indexin relation to three different immersive virtual environment devices. These devices include (1) a headband, (2) 3D glasses, and (3) a head-mounted display (HMD). A quick scale for measuring immersion, feeling of control, and simulator sick…

Influence of interaction techniques o n VIMS in virtual environments : estimation and prediction

2014

Understanding oculo-vestibular dynamics during sensory rearrangement in the central nervous system plays an extremely important role in better understanding human perception, and improves the technology in many engineering fields. Besides, the sensory conflict that occurs between ocular, vestibular and proprioception during sensory rearrangement at certain occasions might adversely affect the user performance in a wide variety of domains including flight/car simulators, scale-one 3D systems, large-scale displays, serious games, and so on. Therefore, knowing the condition in which the sensory conflict happens has a great deal of importance. This study aims at understanding the nature of sens…
