(2020) Pablo Figueroa; Fabián Medina Cortés
La Realidad Virtual (RV) como tecnología generadora de ambientes inmersivos actualmente presenta una notable expansión, y se ha presenciado en múltiples investigaciones en diversos campos de estudio. Reconociendo las virtudes que aporta esta tecnología, como el aumento en motivación y en la efectividad del aprendizaje (por comprender un mayor nivel de inmersión y satisfacción en las actividades realizadas) en los ámbitos educativos y de entrenamiento, se propone evaluar cuál es la configuración de controles (hápticos o tradicionales) más pertinente para mejorar el desempeño y la percepción de usabilidad en los ámbitos mencionados. Así pues, este articulo presenta detalles correspondientes a la elaboración de un prototipo que permita la finalización de tareas básicas para fines educativos y de entrenamiento, en un ambiente de realidad virtual. En este documento nos centramos en las pruebas realizadas al prototipo para definir la interacción más usable a criterio de los participantes del experimento.

Learning How to Play a Guitar with the HoloLens: A Case Study
(2018) Carlos Torres; Pablo Figueroa
This paper introduces a novel application for augmented reality in which it is possible to learn how to play the guitar for a beginner level. It was developed for the Hololens device, following the Suzuki method for instructing the first lesson of the instrument. This prototype utilizes a 2D marker, using the video game engine Unity3D. The prototype was tested comparing the learning experience it offered to the one of a non-immersive learning methodology. As a result, the study did not show any considerable difference between the two methods, but it revealed learners' acceptance towards the augmented reality teaching tool, and it showed information which could be considered to define the research approach for the following stages of the project. It is still necessary to implement several design and functionality improvements to the initial prototype for a new process iteration.
Learning to distinguish Insects from other arthropods with immersive virtual reality
(2021) Víctor Garzón-Marín; Pablo Figueroa; Jorge Molina
Insects are necessary for the prevalence of ecosystems. Insects belong to a group of animals called "Arthropods." Many people ignore how to distinguish them, thus feeling afraid of these animals because of their appearance and usually hurting them. This study explores Immersive Virtual Reality (IVR) as an educational tool focused on allowing users to deduce a rule to distinguish between insects and other arthropods. In total, 21 under graduated students participated in this study. The results indicate that students feel confident when interacting with virtual insects and manage to complete the experience, even when they were afraid of these animals. It is also evident the teacher's importance to guide in interpreting the information that is being received.

Resultados: la literatura encontrada demuestra la efectividad de las tecnologías en el diagnóstico, evaluación y rehabilitación de niños y adolescentes con TDAH. Conclusiones: implementar herramientas basadas en tecnología permiten mejorar la motivación la muestra, manejar diferentes estímulos que proporcionan entornos de aprendizaje, contribuir a la mejora de la sintomatología tanto en el ambiente escolar como en la vida cotidiana y mejorar habilidades no sólo cognitivas sino conductuales en los participantes.
Prototype of a Serious Game for Peace Construction in a Colombian Context
(2018) Fabián Medina; Pablo Figueroa
This article presents a prototype of a serious video game directed to the construction of peace in the Colombian context. We ask participants to identify themselves with a made-up profile, and collaborate with people that are different to their profile. In this indirect way, we pursue the construction of peace by encouraging the conversation among people with different points of view. Preliminary user studies show that our prototype encourages collaboration among participants.
Scalable content for urban applications
(2011) Juan Diego Toro; Pablo Figueroa
We present an application that allows the acquisition of 3D models in an open format that adjust to the device's requirements and specifications. By defining a format in X3D to describe each one of the kinds of objects we have considered as part of an urban model, such as blocks, buildings, cars, pedestrians, streetlights, and massive transportation, among others. This way, the application that requests the urban model can manipulate each of its components independently. The model stores not only graphic representation of objects, but also animation and setup of a certain scene. The application stores in the database scenes as independent objects that can be requested by applications. The application can deliver the same model in different LOD (level of detail) according to the device or application realizing the request.
Shooting simulator for fluvial combat training
(Corporación de Ciencia y Tecnología para el Desarrollo de la Industria Naval, Marítima y Fluvial - COTECMAR, 2012) Carlos Rodríguez; José Tiberio Hernández; Pablo Figueroa
Virtual shooting training has become very attractive because of possible cost reductions and precise evaluation. This article describes the development of a shooting simulator to train soldiers in fluvial combat. This simulator combines the motion of a mechanical platform with virtual imagery and sound to produce an immersive scenario for training purposes. Our prototype, which is in its last phase of construction, has four training tasks with three levels of difficulty. Initially, each task is defined in terms of a virtual trajectory, used by our custom-based motion platform to produce realistic movements, based on a simple dynamic model from real measurements. Our visualization, sound effects, and metrics are implemented on the Torque game engine. Finally, a postprocessor system computes a metrics report.
Study on the Potential of Videogames for Motivating People to Pursue Their Own Goals
(2019) Sergio Madera; Pablo Figueroa
This document describes an experiment to learn more about the potential of videogames to motivate people to pursue their goals. Motivation is important for academic attainment, self-regulated learning, and to live a fulfilling life. Additionally, large amounts of research suggest videogames can teach about diverse topics and motivate people to pursue game related goals. In this experiment, 54 people filled a survey created to measure their motivation levels towards a certain medium-term goal of their own. Then, they were divided into two groups of 27. One was introduced to the videogame Habitica and told to play it at least every two days for two weeks. The other was left alone. After two weeks, both groups filled the survey again. Despite having similar scores initially, at the end, control group scores had decreased significantly more than those from the other, suggesting Habitica was able to motivate players to achieve their goals.

The Influence of Metaverse Environment Design on Learning Experiences in Virtual Reality Classes: A Comparative Study
(2024) Valentina Uribe; Pablo Figueroa; Vivian Gómez
This study explores the potential of metaverse technologies for virtual education, comparing four platforms: Workrooms, Spatial, Mozilla Hubs, and Arthur. We evaluate factors like avatars, spatial arrangement, mobility, and functionalities' impact on concentration, usability, presence, and learning. While learning outcomes show no significant differences, substantial variations in the classroom experience emerge. Metaverses with limited movement and functionalities exhibit higher immersion, concentration, and presence. Moreover, avatars with enhanced facial expressiveness positively influence the overall learning experience.
