Influence of interaction techniques o n VIMS in virtual environments : estimation and prediction

2014

Understanding oculo-vestibular dynamics during sensory rearrangement in the central nervous system plays an extremely important role in better understanding human perception, and improves the technology in many engineering fields. Besides, the sensory conflict that occurs between ocular, vestibular and proprioception during sensory rearrangement at certain occasions might adversely affect the user performance in a wide variety of domains including flight/car simulators, scale-one 3D systems, large-scale displays, serious games, and so on. Therefore, knowing the condition in which the sensory conflict happens has a great deal of importance. This study aims at understanding the nature of sens…

The Society 4.0, Internet, Tourism and the War on Terror

2019

The 9/11 marked the end of an epoch, or so it is claimed by many voices. Scholars and colleagues of all stripes agree that the attacks on the World Trade Center changed international relations and geopolitics as never before. In this context, this chapter interrogates the ramifications of terrorism, its connection with media society and with Society 4.0. As Slavoj Žižek puts it, 9/11 was not only a founding event, but it also woke the Occident from its slumber. In view of this, terrorism paradoxically not only uses the media and digital technologies to instil its message in society, but alerts us to the risks posed by virtuality. This chapter, henceforth, continues Žižek’s reflections unvei…

Computer assisted language learning and the internationalisation of the Portuguese language in higher education contexts

2015

The internationalisation of the Portuguese language has become a priority for academic institutions of different Portuguese-speaking countries which are trying to adapt to the current context of globalisation and ubiquitous communications through digital media. In order to achieve it, several challenges should be faced, namely providing international students with resources aimed at helping them improve their Portuguese while fostering its use in academic and scientific contexts. This can be done by identifying, creating and editing high-quality teaching materials which bear in mind the sociocultural, political, economic and linguistic contexts; using the Information and Communication Techn…

Pornografía infantil: cambios en las formas de obtención y distribución

2017

RESUMEN: El objetivo de este estudio es sintetizar el conocimiento científico sobre los principales mecanismos empleados para la obtención y distribución de pornografía infantil a lo largo de la historia. Para ello, se ha realizado una búsqueda exhaustiva de los trabajos publicados hasta 2016, siendo seleccionados un total de 37. Los resultados obtenidos permiten diferenciar cuatro grandes etapas del tráfico de pornografía infantil (comercial, informatizada, Internet, oculta), en las que los consumidores han migrado hacia tecnologías que les resultan más atractivas y adecuadas para sus fines (Deep Web y redes p2p sin filtro). Sin embargo, un sistema descentralizado como Internet impide la a…

Towards Successful Implementation of a Virtual Classroom for Vocational Higher Education in Indonesia

2019

The virtual classroom continues to grow, but it is becoming more and more the norm, and it is fundamentally different from the vocational students at the Indonesian university. With the promised benefits of the virtual classroom, many challenges and difficulties come in the implementation. Although there are already successful design principles for virtual classrooms that support organizations in overcoming the challenges, the approach to implementing the design principles of virtual classroom at the vocational higher education in Indonesia is still lacking. In this study, we aim to answer the research gap and used the design sciences research by interviewing the lecturers to design the sol…

A Simulation Analysis of VSM Control for RES plants in a Small Mediterranean Island

2020

The paper presents an application of Virtual Synchronous Machine control for managing inverter-interfaced renewable energy sources in a small Mediterranean island not supplied by the main grid. In the proposed analysis, the island's renewables-based generators area assumed interfaced to the grid by voltage source converters with a swing controller and a vector-current controller with two different options for the reference current for regulating the voltage at the Point of Common Coupling and the active power output. The system, modeled in PScad environment, allows to verify the response of the renewables-based generators with VSM control in the presence of a fault in the grid.

A VR/AR Environment for Multi-User Liver Anatomy Education

2021

We present a Virtual and Augmented Reality multi-user prototype of a learning environment for liver anatomy education. Our system supports various training scenarios ranging from small learning groups to classroom-size education, where students and teachers can participate in virtual reality, augmented reality, or via desktop PCs. In an iterative development process with surgeons and teachers, a virtual organ library was created. Nineteen liver data sets were used comprising 3D surface models, 2D image data, pathology information, diagnosis and treatment decisions. These data sets can interactively be sorted and investigated individually regarding their volumetric and meta information. The …

Sociability in Virtual Reality

2021

This study investigates sociability in the context of immersive Virtual Reality (VR). A Design Science Research process was applied, and three iterative development versions of a VR application were studied. Sociability around the technology was investigated with two theoretical perspectives: social presence and social interactions. The results of qualitative interviews and observations as well as a quantitative experiment are combined to make a proposal for four design principles enhancing the beneficial sociability of VR systems. These principles address the importance of ease-of-use and personalization in the activation of a customer, customer empowerment and emancipation through familia…
