Multimodal user interface for a semi-robotic visual assistance system for image guided neurosurgery
2005
Abstract We developed a visual assistance system for image guided neurosurgery, consisting of a stereoscopic digital camera (exoscope) mounted on a semi-robotic manipulator. In order to minimize the operation time, the application-specific multimodal user interface enables hands-free manipulation of the exoscope. The surgeon wears thereby a head-mounted unit with a binocular display, a head tracker, a microphone and earphones. Different modes of view positioning and adjustment can be selected by voice and controlled by head rotation while pressing a miniature confirmation button mounted on a finger ring or suction device. Apart from the development of the mechatronic and software modules of…
Experiences and motivations of the young for participation in virtual worlds
2010
Abstract The aim of this paper is to analyze the motivations and experiences of children to utilize virtual worlds. The paper identifies the activities that children perform in virtual worlds, features they use as well as the reasons for abandoning these virtual worlds. The paper presents results of a qualitative field study. The results indicate that features that are liked in the virtual worlds are similar to games. The main reasons to abandon virtual worlds were increased needs for social networking and better gaming experiences. Students showed interest in using games and virtual worlds at schools, but were generally rather skeptic about this possibility.
Application of remote experiments in a secondary school using MOOC approach
2017
This paper presents first attempt to incorporate remote and virtual experiments in MOOC environment for the secondary school instruction. In case study the VISIR+ remote experiment of the WebLab-Deusto was used. The basic topic of physics “Resistors in series” was suggested for the mentioned above experiment. The open edX platform was employed to build the MOOC for the school lesson — we named it ‘micro-MOOC’. The results could be helpful for secondary school sector representatives, education instructors, parents and policy makers to respond to current and future education needs.
Toward Successfully Integrating Mini Learning Games into Social Virtual Reality Environments : Recommendations for Improving Open and Distance Learni…
2017
Social virtual reality environments, also known as 3D virtual immersive environments, are threedimensional computer-generated virtual spaces that are increasingly used in attendance-based and distance education. Thanks to their unique characteristics that separate them from two-dimensional virtual learning environments, social virtual reality environments can enhance distance education efficacy when used in combination with applying instructional methodologies such as situated learning, experiential learning and game-based learning. The authors of this paper describe the design and findings of a research study on game-based learning in social virtual immersive environments. The research met…
Surveying, Analysis and 3D Modeling in Archaeological Virtual Reconstruction. The inner colonnade of the naos of Temple G of Selinunte.
2012
This paper is focused on the virtual reconstruction of a portion of the naos of Temple G of Selinunte, as a case study for the definition of a method of virtual anastylosis and reconstruction of collapsed colonnades in archaeological contexts. Reconstruction is based on the combination of historical research, archaeological analysis, digital surveying, image-based modeling and laser scanning methods. The complexity of the ruins of the temple suggested a thorough archaeological analysis of the fragments of the inner colonnade of the naos. This analysis made it possible to identify reference surfaces and protective or sacrificial surfaces. The study of these surfaces, together with the dimens…
Magnetic Resonance Imaging in Gastroenterology: Time to Say Good-bye to All That Endoscopy?
2000
Magnetic resonance imaging (MRI) has been described as the most important development in medical diagnosis since the discovery of the roentgen ray more than 100 years ago. The effectiveness of MRI has been extended to make it applicable in a wide variety of gastrointestinal disorders. The attention of gastroenterologists is currently focusing on pancreaticobiliary and bowel diseases. Magnetic resonance cholangiopancreatography (MRCP) has become a competitive alternative to diagnostic endoscopic retrograde cholangiopancreatography in a variety of hepatobiliary and pancreatic diseases. Magnetic resonance enteroscopy has the potential to become the preferable method for evaluating the entire s…
Supporting Mobile Virtual Team’s Coordination with SOA-Based Active Entities
2007
The use of IT solutions to support preparedness, response and recovery process has been envisioned as a possible way to improve the support for collaboration among the actors participating in mobile teams operating under constrained scenarios. Software applications supporting mobility have typically been conceived as functional extensions of centralized enterprise systems hosted on corporate servers. However, in this work, we focus on those mobile scenarios which go one step further in terms of interoperability requirements. This proposal aims to support the design, deployment and execution of ad-hoc collaborative business processes (workflows) in mobile networks, operating under constraine…
Les spectacles à Antioche d’après Libanios
2008
The subject of my contribution might seem very wide. I intend, in fact, to develop it in two main directions: the theatrical shows and those of the circus. If Antioch people’s entertainment reaches its peak in the Olympic Games and Syriarch’s spectacles, more common ones were provided by theatrical shows and chariot-races. I shall study the part of these ordinary spectacles in Antioch people’s life, beginning with generalities on the already well-known world of actors, mimes and pantomimes, without lingering however, in order to move on to what I would like to focus: the circus world, the equestrian competitions which took place in the hippodrome, and the exaltation which they aroused. Abou…
Entertainment virtual reality system for simulation of spaceflights over the surface of the planet Mars
2006
In recent years Virtual Reality technologies have enabled astronomers to recreate and explore three dimensional structures of the Universe for scientific purposes. Mars, due to its scientific interest,has been the focal point of numerous research projects using these technologies, however, none of these virtual reality tools have been developed specifically for entertainment purposes.The focus of this paper is to present MarsVR, as an entertainment research project that educates people on the topography and orography of the planet Mars from the perspective of popular science. Some projects have been designed MarsVR for entertainment purposes and include the latest advances in 3D real time a…
The Globalization of Fear
2017
In this chapter, we combine the advances of other disciplines to expand our understanding of terrorism and the fields of emotions. In this respect, as L. Howie puts it, the media industry engendered a culture of witnessing which not only is conducive to terrorism, but enlarged fear to other continents. The globalization of fear operates in a new field which is based on what Baudrillard named ‘the spectacle of disaster’. Though this vicious circle between the spectatorship of disaster and terrorism not to be broken, the problem is far from being solved. Terrorism and 9/11 as founding event ignited a new stage of capitalism which Korstanje called ‘Thana-Capitalism’. Unlike modern sociologist …
