Entertainment virtual reality system for simulation of spaceflights over the surface of the planet Mars
2006
In recent years Virtual Reality technologies have enabled astronomers to recreate and explore three dimensional structures of the Universe for scientific purposes. Mars, due to its scientific interest,has been the focal point of numerous research projects using these technologies, however, none of these virtual reality tools have been developed specifically for entertainment purposes.The focus of this paper is to present MarsVR, as an entertainment research project that educates people on the topography and orography of the planet Mars from the perspective of popular science. Some projects have been designed MarsVR for entertainment purposes and include the latest advances in 3D real time a…
An Application of Ant Colony Optimization to Decision Making on Affective Virtual Entities
2007
Learning is a never ending activity for humans; it takes place everywhere and even when we do not realize. However, current learning environments make students deal with lectures, mostly associated with low control of the situation and implicit motivation. In contrast, previous researches have shown that sports, games or hobbies are activities that make people reach optimal experiences where self-motivation, control of the situation, high level of concentration and enjoyment are present. Some current efforts to design next generation of learning environments make use of ubiquitous systems to encourage students to perform learning activities everywhere and at anytime. However, those approach…
Alternative Income Sources – Entrepreneurship Development or Households’ Economic Needs after the COVID-19 Crisis?
2021
Purpose: The purpose of this paper is to identify and analyze the COVID-19 pandemic implications for alternative income sources in transition economy with the dispute based on literature and research. Design/Methodology/Approach: The following research methods were used. Desk extensive research and analysis of raw data collected for the study. An original in-depth interview form was developed, and scientific dispute based on subject literature was conducted. A research hypothesis, aimed at verifying the research problem, were formulated. Findings: The study highlights that, aside from passion, the main reason for undertaking additional economic activity is to obtain additional income. Pract…
The New Era of Business Digitization through the Implementation of 5G Technology in Romania
2021
The main objective of the present research is to identify the advantages and benefits that the use and implementation of 5G technology has on the development and evolution of the Romanian business environment. The study is based on a theoretical documentation regarding existing information in the field and a descriptive analysis of the evolution of the technology in Romania and worldwide. The research method chosen is a survey based on an opinion poll (questionnaire) to find out the availability of economic entities regarding the implementation of 5G technologies, the foreseen expectations and those realized by the business environment regarding the effects of 5G technologies on the economi…
Le repas à l'épreuve du cancer : une rédéfinition sensorielle, sensible et symbolique
2015
This contribution is focused on patients' food practices affected by cancer and cure. The led analyses wish to understand the break linked to the disease and cures to question ways either sensory or symbolic which determine the food choices.
Effectiveness of Virtual Reality for Children and Adolescents with Autism Spectrum Disorder: An Evidence-Based Systematic Review
2018
Autism Spectrum Disorder (ASD) is a neurodevelopmental disease that is specially characterized by impairments in social communication and social skills. ASD has a high prevalence in children, affecting 1 in 160 subjects. Virtual reality (VR) has emerged as an effective tool for intervention in the health field. Different recent papers have reviewed the VR-based treatments in ASD, but they have an important limitation because they only use clinical databases and do not include important technical indexes such as the Web of Science index or the Scimago Journal & Country Rank. To our knowledge, this is the first contribution that has carried out an evidence-based systematic review includin…
A Multimodal Guide for Virtual 3D Models of Cultural Heritage Artifacts
2008
The area of cultural heritage preservation and fruition has drawn an ever growing attention of artificial intelligence and human-computer interaction research in the last decades. The common aim is to develop systems that can interact with the user in a variety of modes and in the most natural way. In this paper, a multimodal guide for virtual 3D environment navigation is presented. The proposed system integrates X3D environment with a multimodal interface. The application scenario is to provide a visitor assistance and guidance during the visit of one of the halls in the historical Palazzo Steri, the headquarters of the University of Palermo.
An Augmented Reality (AR) CAD System at Construction Sites
2011
Augmented Reality (AR) technologies allow computer-generated content to be superimposed over a live camera view of the real world. Although AR is still a very promising technology, currently only a few commercial applications for industrial purposes exploit the potential of adding contextual content to real scenarios. Most of AR applications are oriented to fields such as education or entertainment, where the requirements in terms of repeatability, fault tolerance, reliability and safety are low. Different visualization devices, tracking methods and interaction techniques are described in the literature, establishing a classification between Indoor and Outdoor AR systems. On the one hand, t…
The Self-expression Motivational System
2016
The main aim of this chapter is to introduce and promote the concept of self-expression as a basic motivation. Considering that the amount of literature on self-expression, matched with the concepts of control and affiliation, is practically non-existent, the chapter starts by attempting to provide a viable definition of self-expression motivation. Furthermore, the concept of art as a domain in which the underlying tendency for self-expression is clearly manifested is also considered. The chapter also includes a literature review to show whether or not self-expression motivation is able to fulfil the criteria suggested by Baumeister and Leary (Psychological Bulletin, 117, 497–529, 1995). Th…
“You look at it, but will you choose it”: Is there a link between the foods consumers look at and what they ultimately choose in a virtual supermarke…
2022
Most of the studies that showed a link between gaze allocation and consumer's food choices were performed on food products belonging to a same category. However, consumers usually make food choices in more complex environments, between many different products, and different factors can influence their choices. Therefore, our study aimed to understand the link between gaze behavior and food choices in a complex and realistic situation of choice. Participants (n=99) performed a food choice task in a virtual supermarket. They had to choose three food products to create a dish in four scenarios evoking different motivations (focus on health, environment, food pleasure, and daily scenario as con…
