The use of virtual environments as an extended classroom – A case study with adult learners in tertiary education

This study was conducted in immersive 3D virtual environment Second Life®, with the support of web 2.0 tools as a complement to physical classroom - extended classroom. It was assumed that socialization is a key factor for collaborative learning and knowledge construction. The study aims to identify the variables that may influence knowledge sharing in learning contexts using virtual environments; with the aim of contributing to the improvement of learning situations using the online tools. This research is exploratory in nature and falls within the field of phenomenological studies. The study was implemented in a tertiary education institution involving regular and adult learners. We conclude that in virtual environments learners tend to feel more confident, open, participatory, creative, understanding and seem to participate in training sessions because they are indeed interested in learning. On the other hand, the possibility of providing online tutorial session allows reaching a larger number of learners. These online sessions can be established in a time and place (virtual) free of constraints and can be tailored, allowing a more effective participation from learners.info:eu-repo/semantics/publishedVersio

Personalization in cultural heritage: the road travelled and the one ahead

Over the last 20 years, cultural heritage has been a favored domain for personalization research. For years, researchers have experimented with the cutting edge technology of the day; now, with the convergence of internet and wireless technology, and the increasing adoption of the Web as a platform for the publication of information, the visitor is able to exploit cultural heritage material before, during and after the visit, having different goals and requirements in each phase. However, cultural heritage sites have a huge amount of information to present, which must be filtered and personalized in order to enable the individual user to easily access it. Personalization of cultural heritage information requires a system that is able to model the user (e.g., interest, knowledge and other personal characteristics), as well as contextual aspects, select the most appropriate content, and deliver it in the most suitable way. It should be noted that achieving this result is extremely challenging in the case of first-time users, such as tourists who visit a cultural heritage site for the first time (and maybe the only time in their life). In addition, as tourism is a social activity, adapting to the individual is not enough because groups and communities have to be modeled and supported as well, taking into account their mutual interests, previous mutual experience, and requirements. How to model and represent the user(s) and the context of the visit and how to reason with regard to the information that is available are the challenges faced by researchers in personalization of cultural heritage. Notwithstanding the effort invested so far, a definite solution is far from being reached, mainly because new technology and new aspects of personalization are constantly being introduced. This article surveys the research in this area. Starting from the earlier systems, which presented cultural heritage information in kiosks, it summarizes the evolution of personalization techniques in museum web sites, virtual collections and mobile guides, until recent extension of cultural heritage toward the semantic and social web. The paper concludes with current challenges and points out areas where future research is needed

Examining the role of smart TVs and VR HMDs in synchronous at-a-distance media consumption

This article examines synchronous at-a-distance media consumption from two perspectives: How it can be facilitated using existing consumer displays (through TVs combined with smartphones), and imminently available consumer displays (through virtual reality (VR) HMDs combined with RGBD sensing). First, we discuss results from an initial evaluation of a synchronous shared at-a-distance smart TV system, CastAway. Through week-long in-home deployments with five couples, we gain formative insights into the adoption and usage of at-a-distance media consumption and how couples communicated during said consumption. We then examine how the imminent availability and potential adoption of consumer VR HMDs could affect preferences toward how synchronous at-a-distance media consumption is conducted, in a laboratory study of 12 pairs, by enhancing media immersion and supporting embodied telepresence for communication. Finally, we discuss the implications these studies have for the near-future of consumer synchronous at-a-distance media consumption. When combined, these studies begin to explore a design space regarding the varying ways in which at-a-distance media consumption can be supported and experienced (through music, TV content, augmenting existing TV content for immersion, and immersive VR content), what factors might influence usage and adoption and the implications for supporting communication and telepresence during media consumption

Emotion capture based on body postures and movements

In this paper we present a preliminary study for designing interactive systems that are sensible to human emotions based on the body movements. To do so, we first review the literature on the various approaches for defining and characterizing human emotions. After justifying the adopted characterization space for emotions, we then focus on the movement characteristics that must be captured by the system for being able to recognize the human emotions.Comment: 22 page

Illustration, re-enactment, citizenship and heritage of contemporary conflict: the case of the Ebro (1938)

Historical illustrations give us hypothetical visual reconstructions of the past, which contribute to their interpretation, knowledge, and understanding. The progress of software for the design and production of images has optimized the possibilities of generating models of educational and understandable illustrations of spaces, facts, and concepts of the past. At the same time, promoting historical recreation activities allows us to obtain photographic and moving images of a historical nature, which can be integrated into image processing software. This paper describes the experience of the DIDPATRI group (Heritage Education, comprehensive museography and new technologies) the University of Barcelona with the Battle of the Ebro (Spanish Civil War, 1938), concerning the design of models/educational illustrations of the conflict. The developed actions show that, with well-defined criteria, support for recreation, and basic but highly educational software that is understandable and replicable, iconographic models can be obtained at a reasonable cost. The final result provides us with the possibility to understand the past in greater detail. The heritage of the conflict gives us the possibility to reflect, thereby directly affecting the formation of quality citizenship

A 3D virtual environment for social telepresence

We examine OnLive Traveler as a case study. Traveler is a clientserver application allowing real-time synchronous communication between individuals over the Internet. The Traveler client interface presents the user with a shared virtual 3D world, in which participants are represented by avatars. The primary mode of communication is through multi-point, full duplex voice, managed by the server. Our design goal was to develop a virtual community system that emulates natural social paradigms, allowing the participants to sense a tele-presence, the subjective sensation that remote users are actually co-located within a virtual space. Once this level of immersive "sense of presence" and engagement is achieved, we believe an enhanced level of socialization, learning, and communication are achievable. We examine a number of very specific design and implementation decisions that were made to achieve this goal within platform constraints. We also will detail some observed results gleaned from the virtual community userbase, which has been online for several year

Prefrontal cortex activation upon a demanding virtual hand-controlled task: A new frontier for neuroergonomics

open9noFunctional near-infrared spectroscopy (fNIRS) is a non-invasive vascular-based functional neuroimaging technology that can assess, simultaneously from multiple cortical areas, concentration changes in oxygenated-deoxygenated hemoglobin at the level of the cortical microcirculation blood vessels. fNIRS, with its high degree of ecological validity and its very limited requirement of physical constraints to subjects, could represent a valid tool for monitoring cortical responses in the research field of neuroergonomics. In virtual reality (VR) real situations can be replicated with greater control than those obtainable in the real world. Therefore, VR is the ideal setting where studies about neuroergonomics applications can be performed. The aim of the present study was to investigate, by a 20-channel fNIRS system, the dorsolateral/ventrolateral prefrontal cortex (DLPFC/VLPFC) in subjects while performing a demanding VR hand-controlled task (HCT). Considering the complexity of the HCT, its execution should require the attentional resources allocation and the integration of different executive functions. The HCT simulates the interaction with a real, remotely-driven, system operating in a critical environment. The hand movements were captured by a high spatial and temporal resolution 3-dimensional (3D) hand-sensing device, the LEAP motion controller, a gesture-based control interface that could be used in VR for tele-operated applications. Fifteen University students were asked to guide, with their right hand/forearm, a virtual ball (VB) over a virtual route (VROU) reproducing a 42 m narrow road including some critical points. The subjects tried to travel as long as possible without making VB fall. The distance traveled by the guided VB was 70.2 ± 37.2 m. The less skilled subjects failed several times in guiding the VB over the VROU. Nevertheless, a bilateral VLPFC activation, in response to the HCT execution, was observed in all the subjects. No correlation was found between the distance traveled by the guided VB and the corresponding cortical activation. These results confirm the suitability of fNIRS technology to objectively evaluate cortical hemodynamic changes occurring in VR environments. Future studies could give a contribution to a better understanding of the cognitive mechanisms underlying human performance either in expert or non-expert operators during the simulation of different demanding/fatiguing activities.openCarrieri, Marika; Petracca, Andrea; Lancia, Stefania; Basso Moro, Sara; Brigadoi, Sabrina; Spezialetti, Matteo; Ferrari, Marco; Placidi, Giuseppe; Quaresima, ValentinaCarrieri, Marika; Petracca, Andrea; Lancia, Stefania; BASSO MORO, Sara; Brigadoi, Sabrina; Spezialetti, Matteo; Ferrari, Marco; Placidi, Giuseppe; Quaresima, Valentin

open access articleBackground: Art enhances both physical and mental health wellbeing. The health benefits include reduction in blood pressure, heart rate, pain perception and briefer inpatient stays, as well as improvement of communication skills and self-esteem. In addition to these, people living with dementia benefit from reduction of their noncognitive, behavioural changes, enhancement of their cognitive capacities and being socially active. Methods: The current study represents a narrative general literature review on available studies and knowledge about contribution of Artificial Intelligence (AI) in creative arts. Results: We review AI visual arts technologies, and their potential for use among people with dementia and care, drawing on similar experiences to date from traditional art in dementia care. Conclusion: The virtual reality, installations and the psychedelic properties of the AI created art provide a new venue for more detailed research about its therapeutic use in dementia

Educating future product developers in collaborative product development : lessons learned from the european global product realization (EGPR) international course

Changes in the business environment, responses of companies to these changes and the available information and communication technologies (ICT) pose a number of challenges to present and future product developers, as well as to educational institutions. An appropriate response to these challenges is to create a solid basis for strategies to combat stronger competition, since existing educational programs have provided this only to a small extent. In our opinion, the E-GPR course carried out by 5 European universities reflects the tasks of professional product development teams and their work conditions as realistically as possible and will enable students attending the E-GPR course who will soon enter the professional world to later progress along a steeper learning curve. This paper focuses on the role of communication between members of virtual teams and presents experiences gathered during the organization, designing and performance of each year’s courses
