Potencial actual de las tecnologías de Realidad Virtual en Turismo: propuesta, caso de estudio y demostración

La Realidad Virtual (RV) es una de las aplicaciones más recientes del campo de las Tecnologías de la Información y puede desempeñar muchos papeles destacados dentro de la industria del turismo. Sin embargo, a pesar de las numerosas aplicaciones potenciales, su uso real es aún muy limitado. En esta comunicación se examinan las aplicaciones teóricas y prácticas de la RV en el turismo en general, pero en la comercialización de la experiencia turística en particular. Se presenta un caso de estudio en el que se combinan distintas tecnologías disponibles en el mercado a un precio relativamente bajo para diseñar una experiencia novedosa. Así pues, se han integrado 6 cámaras GoPro Hero en un soporte adecuado para poder generar un video 360º. Mediante un desarrollo propio, el video 360º es proyectado en el interior de una esfera, donde se ubica una cámara virtual cuya orientación es sincronizada con el movimiento de las gafas de Realidad Virtual (Oculus Rift). Esta solución permite al usuario mover libremente la cabeza y explorar el vídeo desde cualquier punto de vista, con una experiencia de inmersión difícilmente igualable. La primera experiencia propuesta se ha llevado a cabo en la Cabalgata de Reyes Magos de Alcoy, la más antigua del mundo y con mayor repercusión mediática. Se han capturado vídeos 360º de los momentos más destacados de este evento como, por ejemplo, la subida de los pajes reales a los balcones de la ciudad, para entregar los regalos a los niños. Esta experiencia de RV estuvo disponible en el stand de Alcoy en la Feria Internacional del Turismo de 2014 (FITUR) donde fue utilizada como reclamo publicitario. La solución propuesta permite elaborar experiencias de RV de gran calidad y reproducirlas a un coste relativamente bajo, lo que hará posible un uso cada vez más generalizado de estas tecnologías. En un futuro próximo se integrarán nuevos componentes y software propio que, también por un coste moderado, mejorarán aún más las experiencias de RV que se puede utilizar para promocionar los eventos y lugares turísticos nacionales

Large Language Models for in Situ Knowledge Documentation and Access With Augmented Reality

Augmented reality (AR) has become a powerful tool for assisting operators in complex environments, such as shop floors, laboratories, and industrial settings. By displaying synthetic visual elements anchored in real environments and providing information for specific tasks, AR helps to improve efficiency and accuracy. However, a common bottleneck in these environments is introducing all necessary information, which often requires predefined structured formats and needs more ability for multimodal and Natural Language (NL) interaction. This work proposes a new method for dynamically documenting complex environments using AR in a multimodal, non-structured, and interactive manner. Our method employs Large Language Models (LLMs) to allow experts to describe elements from the real environment in NL and select corresponding AR elements in a dynamic and iterative process. This enables a more natural and flexible way of introducing information, allowing experts to describe the environment in their own words rather than being constrained by a predetermined structure. Any operator can then ask about any aspect of the environment in NL to receive a response and visual guidance from the AR system, thus allowing for a more natural and flexible way of introducing and retrieving information. These capabilities ultimately improve the effectiveness and efficiency of tasks in complex environments

That approach might become obsolete in a new context in which developers must create applications for smart phones, tablets, and rich Internet applications. Teaching computer graphics in this situation is becoming difficult; traditional tools don't address these new requirements in an integrated way. To deal with this situation, the Processing development environment provides high-end solutions in visualization, animation, and interaction, while letting students deploy their programs on desktop computers, smart phones, tablets, and websites. Instructors can introduce devices and interaction paradigms in just a few hours. In an introductory computer graphics course, Processing dramatically boosted students' motivation. Their work wasn't just visible in the lab; they could show it to classmates and friends on their own smart phones, tablets, and websites. © 2006 IEEE.Linares Pellicer, JJ.; Micó Tormos, P.; Esparza Peidro, J.; Carrasquer Moya, MA.

Definition of a Coordinated Project-Based Learning Teaching Guide at Computer Science Studies

[EN] The well-known active methodology of Project-Based Learning (PBL) is being used more and more at different educational levels due to the large number of advantages it presents. PBL has demonstrated that increases students' motivation, develops their autonomy and capacity for self-criticism, reinforces the ability to exchange ideas and collaborate, and promotes creativity, among other advantages. Due to these benefits, several educational institutions are introducing the PBL methodology in their teaching-learning processes. The implementation phase of this type of methodology should be planned, managed, and carried out carefully, considering several aspects. One of utmost importance is to collect and register all the critical information related to the contents, materials and activities of the subjects participating in the coordinated project through the PBL methodology. In this sense, the objective of this paper is to propose the definition of a coordinated PBL Teaching Guide that includes all this relevant information; containing, mainly: (i) PBL Project description; (ii) recommended previous knowledge; (iii) learning objectives and outcomes; (iv) PBL model milestones; (v) PBL model planning; (vi) evaluation; and (vii) bibliography. Furthermore, this proposal will define the formal guidelines for students and lecturers to define and frame all the related aspects to carry out the proposed PBL model. The definition of the PBL Teaching Guide will be based on a case study that involves the following two subjects from the Computer Engineering Degree that are taught at the Escola Politècnica Superior d¿Alcoi (EPSA) - Universitat Politècnica de València (UPV): ¿Programming¿ and ¿Data Structures and Algorithms¿. This proposal has been developed in the context of an innovation and educational improvement project applied in the EPSA during the last two years, covering five degrees, 55 subjects, and more than 10 different PBL models.This article has been supported by the Vice-rectorate for Digital Resources and Documentation (Vicerrectorado de Recursos Digitales y Documentación) and Vice-Rectorate for Studies, Quality and Accreditation (Vicerrectorado de Estudios, Calidad y Acreditación) under the Call for Learning + Teaching (Convocatoria Aprendizaje + Docencia (A+D 2019)) and Project Code: A-157.

Towards Inter-Subject Project-Based Learning in Programming-Related Courses at Computer Science Studies

[EN] Curriculum design of University Degrees in Spain is mainly based on scheduling atomic, self-contained semester subjects during a 4-year period. This scheduling is driven by one major constraint: to ensure that previous subject pre-requisites are met for each course. Thus, basic subjects without college-level pre-requisites are typically scheduled in the first year, first semester, while the rest are properly planned in a sequential manner, complying the aforementioned condition. This is, basically, the only proof of inter-subject coordination in such degrees, taking place at the design stage. During the academic period, however, there is no vertical nor horizontal inter-subject coordination, not even among closely-related subjects. In order to increase inter-subject coordination and to exploit its potential benefit for students, the projectbased learning (PBL) methodology shows on the scene. This approach organizes learning around student-driven projects aiming to solve real-life problems. This close applicability to the real world expedites intrinsic motivation of students, and consequently, their learning process tends to be deeper and more significant. Furthermore, PBL applied at the inter-subject level increases curriculum cohesion and makes students more engaged and compromised with its global objectives. In this paper we describe the design of PBL models involving two pairs of programming-related subjects from the Computer Engineering Degree at the Universitat Politècnica de València. The first one associates the ¿Programming¿ with the ¿Data Structures and Algorithms¿ subject, while the second one engages the ¿Introduction to Video-Games Programming¿ with the ¿Digital Image Synthesis¿ one. It is an ambitious pilot programme that will require a high coordination effort among participating professors and student teams.This article has been supported by the Vice-rectorate for Digital Resources and Documentation (Vicerrectorado de Recursos Digitales y Documentación) and Vice-Rectorate for Studies, Quality and Accreditation (Vicerrectorado de Estudios, Calidad y Acreditación) under the Call for Learning + Teaching (Convocatoria Aprendizaje + Docencia (A+D 2019)) and Project Code: 1678-A.
