A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens

2017

The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…

Nouvelles technologies et aide à la compréhension de documents techniques : Construction et expérimentation d'un simulateur de fonctionnement de grue…

2001

Reading skills are more and more required to succeed professional examination. French crane drivers are concerned with this problem. In order to help them, we have conducted a study with three main steps. First, we carried out a cognitive work analysis. Second, we test several analogical modalities of written presentations focusing on the construction of a specific simulator. Finally, two experiments are presented showing a significative effect of this simulator on the comprehension of cranes technical documentation.

La politique éolienne et ses effets sur le développement local. Une analyse basée sur le système des acteurs (Loja, Equateur)

2020

La política energética ecuatoriana pretende que las centrales eléctricas contribuyan al desarrollo local en las áreas en las que se implantan. A partir del caso de estudio del Parque Eólico Villonaco (PEV), la pregunta de investigación que se plantea es si el Plan de Desarrollo Territorial Comunitario (PDTC) que se está implementando en la zona de influencia del Parque, está teniendo efectos socio-territoriales positivos. Se utiliza una metodología cualitativa, a partir de entrevistas semiestructuradas a actores clave. Los resultados obtenidos indican que la central eólica ha empezado a tener efectos positivos en el ámbito de los equipamientos educativos, la infraestructura vial, o en el al…

Tecnologías de información y contabilidad de gestión: evidencia empírica de la autoridad portuaria de Valencia

2008

Ports that have good geographical location, efficient management and value-added services have potential for international leadership, as is the case with the Valencia Port Authority, which figures prominently in the international ranking of container ports. Information systems should stimulate the curiosity of organizations, facilitate the process of participatory decision-making and enhance the ability of the organization to cope with changes in the environment. Changes occurring in the environment fully affect the organization and therefore its computer systems. Through the study of the Business Intelligence Systems at the Valencia Port Authority, we seek to reaffirm the assumptions of t…

What drives travelers' adoption of user-generated content? : A literature review

2018

User-generated content (UGC) has become an important part of travel planning, as travelers evaluate travel products based on past reviews. However, different factors account for why tourists utilize UGC. The aim of this study is to review extant studies on UGC to identify the antecedents of UGC utilization for travel planning and the theories, models, and frameworks used in these studies. A total of 54 studies from 2005 to 2016 were found. This study found that UGC adoption is determined by attributes relating to the user, the source, the content, and response variables. It also found distinct and heterogeneous theories and frameworks mainly drawn from the information systems, socio-psychol…

The hierarchy of needs for user experiences in virtual reality

2021

Virtual reality (VR) is rapidly becoming more widely adopted by various industries, and virtual content is just as rapidly becoming available for consumers. However, there is a lack of guidelines and standards for VR content to be held to in terms of experiential design. Because VR is a relatively new media form for consumers, there is a high risk of user attrition due to the novelty of the service. Therefore, if the first experience of the technology is with poorly made content, users will be much less likely to use VR again. Therefore, as various industries and organizations digitalize and adopt emerging technology such as VR, great care should be given to the way the virtual content and …
