Article
Full-text available
We present a virtual reality simulation of an evacuation caused by a trembling earthquake in a secondary school. The simulation is based on artificial intelligence for which a mathematical model is implemented that controls the behavior of agents that represent the school students in the virtual stage. The simulation allows the interaction with the...
Article
Full-text available
In this paper a model to integrate the technology of tutoring systems to existing virtual reality training systems is described. The training systems are devoted to dangerous activities for energized line maintenance in the electrical domain. The systems are already in use and have impacted positively the traditional training method, which was base...
Article
Full-text available
A number of different approaches to build adaptive user interfaces for web-based systems and office applications have been reported in the literature. However, for more demanding domains such as the operation of a power plant, little research has been conducted. To operate a power plant, the operator has to visualize information, analyze normal and...
Conference Paper
In the operation of a power plant, the operator has to deal with a number of variables displayed in several windows, presented in different formats such as tabular, oneline diagrams, process diagrams, etc. Under these conditions, the operator needs to locate data relevant to the current status of the plant and efficiently navigate a large number of...
Conference Paper
The present work presents a methodology that has been developed and successfully applied to support the information requirements of engineers in charge of the operation, modernization, and/or maintenance of energy production plants (power, oil and gas). Commercial CAD software systems have been utilized to create comprehensive three-dimensional (3D...
Article
Full-text available
This paper describes the design process for prototyping a three-dimensional desktop virtual environment. The design model encompasses evaluation as the central part of the design process. Design implications derived from a formative evaluation are described in terms of navigation, object interaction and affordance perception. The design process is...
Chapter
Full-text available
In this chapter we present the current advances in the field of adaptive user interfaces, analysing the different research efforts, the challenges involved as well as the more recent and promising directions in this field. Initially, we introduce the foundations of adaptive user interfaces, also referred in technical literature as Intelligent User...
Article
Full-text available
Information location and interactivity are two attributes of desktop virtual environment (DVE) design that can be exploited to enhance the ability of learners to acquire information and skills that transfer to real world. The term "information location" refers to the spatial relationship between linguistic information (text and sound) and virtual r...

Conference Paper
Desktop virtual environments offers the possibility to design a manageable space for safety training, in which trainees can experience situations in context, interact with the virtual environment and practice emergency procedures. This paper presents the design process of a desktop virtual reality prototype for safety training for people who works...
Conference Paper
Full-text available
In this paper we review and analyze the current trends and research efforts in the area of adaptive user interfaces (AUIs) for different applications and domains. We present some of the current challenges for AUIs and the three main approaches used to address these challenges: artificial intelligence (AI), user modeling (UM) and human-computer inte...
Conference Paper
The main purpose of this paper is to show the results obtained with the evaluation of 3D (three dimensional) scanners to obtain 3D models or objects which can be used to build virtual reality systems. Firstly, some basic concepts related to this emerging technology are briefly described. Furthermore an evaluation methodology based on MCDM (multi cr...
Article
El Instituto de Investigaciones Eléctricas (IIE) havenido trabajando durante varios años en el área deAMR (Lectura Automática de Medidores, por sus siglas eninglés) así como en la deteccón del robo deenergía eléctrica como líneasestratégicas para el desarrollo de infraestructura interna ytambién como respuesta a las demandas deautomatización de la...
Conference Paper
Full-text available
The purpose of the study reported in this paper was to investigate the effect of two forms of presenting verbal information (co-located and non co- located) on learning and retention of knowledge in a desktop virtual environment. Co-located information refers to the spatial relationship between linguistic information (text and sound) and virtual re...
Conference Paper
This work describes the design, development and implementation of a working prototype of a classroom analysis simulator (CAS) of nuclear processes. CAS is a multi-computer system with a sophisticated advanced graphical human-machine interface. By direct manipulation of virtual instrumentation over touch sensitive screens, the user has full dominion...

Article
Full-text available
This paper describes the design decisions made during the development of VEST-Lab, a desktop Virtual Reality (VR) system for safety training in chemistry laboratories. Realism afforded by VR representations and interactivity issues in desktop VR systems are discussed from the point of view of learner-centred design perspective.
Article
The Nuclear Reactor Engineering Analysis Laboratory (NREAL) is a sophisticated computer system with state-of-the-art analytical tools and technology for analysis of light water reactors. Multiple application software tools can be activated to carry out different analyses and studies such as nuclear fuel reload evaluation, safety operation margin me...
