Manipulating Self-Avatar Body Dimensions in Virtual Worlds to Complement an Internet-Delivered Intervention to Increase Physical Activity in Overweig…
2020
Virtual reality has been found to be a useful tool for positively influencing relevant psychological variables in order to increase physical activity (PA), especially in the overweight population. This study investigates the use of avatars and their physical variations to extend the effectiveness of existing interventions to promote PA. The main objective is to analyze the influence of the avatars&rsquo
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…
The case of literacy motivation : Playful 3D immersive learning environments and problem-focused education for blended digital storytelling
2018
The University of Patras' Library Services designed and offered to primary and secondary schools the pilot educational program “From the Ancient to the Modern Tablets”, featuring immersive multimedia learning experiences about the book history. The pilot program consisted of three stages: a playful library tour, followed by an interactive game-based digital storytelling activity with game elements, and a collaborative creative reflective hands-on activity. Utilizing the avatar psychology power, the visualization and simulation affordances of 3D immersive learning environments and the appeal of storytelling and game-based learning, the “gamified” blended narrative on the book evolution enabl…
Engaging learners through virtual worlds
2010
Abstract The aim of this paper is to explore how virtual worlds could support the engagement for learning. This paper reviews the results of studies that utilized virtual worlds to engage learners. The results are examined in two levels, namely learning gains and design principles. It has been found out that deeper learner engagement results in higher learning gains. In some studies better content retention is also noted. Many studies also suggest design principles for using virtual worlds for facilitating engaged learning. This paper builds a framework for the design and use of virtual worlds in education for better learner engagement.
Experiences and motivations of the young for participation in virtual worlds
2010
Abstract The aim of this paper is to analyze the motivations and experiences of children to utilize virtual worlds. The paper identifies the activities that children perform in virtual worlds, features they use as well as the reasons for abandoning these virtual worlds. The paper presents results of a qualitative field study. The results indicate that features that are liked in the virtual worlds are similar to games. The main reasons to abandon virtual worlds were increased needs for social networking and better gaming experiences. Students showed interest in using games and virtual worlds at schools, but were generally rather skeptic about this possibility.
Optimization of Cultural Heritage Virtual Environments for Gaming Applications
2020
Serious games are games with a purpose beyond entertainment and are widely acknowledged as fruitful tools for learning and developing skills across multiple domains, including educational enhancement. In the last few years, the world of serious games has widely increased. The use of these types of games can aid in classrooms to not only help the students learn concepts but also to improve their motivation to do so. However, designing games necessitates very specialized personnel and the process can often be costly and slow. The adaptions of the design to the implantation phase are also difficult and the process needs more focus. The challenge of this study was to create a game within the co…
Robust Ergonomic Virtual Design
2009
Since early development phases of a new industrial product, realistic simulations can be performed in virtual environment to study the human-machine interaction. In a virtual lab it is possible to make experiments to assess the ergonomics of the new product with manikins simulating the human body, and dealing with the problem of anthropometrical variation. Although such sophisticated tools are available, there is still need of a methodo-logical framework aimed at efficiently organizing the experiments in virtual lab. This paper provides an overview of the Robust Ergonomic Virtual Design (REVD), a methodology developed by the authors in the course of the last years. It allows obtaining produ…
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…
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.
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…
