“…Users experiencing a higher level of presence showed an increased eventrelated desynchronization (ERD) in the Alpha band (8-13 Hz) reflecting increased activation (Pfurtscheller, 1989) in parietal brain regions. Kober, Kurzmann and Neuper (2012) could replicate these findings in an interactive virtual environment, where subjects navigated freely through a virtual world. Baumgartner and colleagues (2006) and Kober, Kurzmann and Neuper (2012) concluded that parietal brain areas might play an important role in the presence experience because these areas are involved in generating an egocentric (body-centred) representation of space (Maguire et al, 1998;Maguire, Burgess and O'Keefe, 1999).…”

“…Baumgartner and colleagues (2006) and Kober, Kurzmann and Neuper (2012) concluded that parietal brain areas might play an important role in the presence experience because these areas are involved in generating an egocentric (body-centred) representation of space (Maguire et al, 1998;Maguire, Burgess and O'Keefe, 1999). Because the presence experience is among other definitions also defined as egocentric spatial experience of virtual worlds, it might be that an egocentric view provided by the parietal lobe is essential for the spatial presence experience in virtual environments (Baumgartner et al, 2008;Jäncke, Cheetham and Baumgartner, 2009;Kober, Kurzmann and Neuper, 2012).…”

Friedrich studied Psychology at the University of Graz, Austria, and conducted her master thesis at the Laboratory of Neural Injury and Repair, Wadsworth Center, Albany, NY. She has received her doctorate in natural science in 2012 at the University of Graz, Austria. Her main research interest is brain-computer interface (BCI). She explored different mental tasks to control an EEGbased BCI, the impact of distraction on user performance as well as improvements of BCI usability for severely motor impaired individuals.

Milos Kravcik has a diploma degree in computer science and a doctoral degree in applied informatics from the Comenius University in Slovakia. He has been dealing with Technology Enhanced Learning (TEL) since 1988 in various national and international projects, later also at the Fraunhofer Institute for Applied Information Technology in Germany and at the Open University in the Netherlands. Since 2010 he works as a Research Fellow at the RWTH Aachen University and his main research interests include personalized learning environments and self-regulated learning. He co-organized several TEL doctoral schools and serves also as executive peer-reviewer or editorial board member for several journals related to learning technologies. As both an academic and researcher with considerable industrial experience, he has been instrumental in the research, analysis and development of virtual engineering environments in a variety of product engineering domains and now focuses his work on the acquisition of engineering knowledge information management systems within all aspect of product engineering; with a particular emphasis on conceptual design. He has also implemented game-based learning methods in design and manufacturing taught courses. With over 40 international publications, a book and the successful commercialisation of his novel feature recognition algorithms, he is now applying his knowledge and expertise to the domain of serious games, game ware and computational biometrics for next generation engineering applications. AbstractThe use of serious games and virtual environments for learning is increasing worldwide. These technologies have the potential to collect live data from users through game-play and can be combined with neuroscientific methods such as EEG, fNIRS and fMRI. The several learning processes triggered by serious games are associated with spec...

“…The preprocessing of EEG signals started with a detrending removal to eliminate the DC offset in the recorded EEG. This was followed by a linear band pass 13 filter (0.5-45 Hz) that removed the effect of 50 Hz noise and higher frequency artifacts based on the method used by Khushaba et al (2012); Kober et al (2012);and Khushaba et al (2013). Then, the electrooculographic and electromyographic artifacts were detected and deleted using the ADJUST method (Mognon et al, 2011), which is based on the Independent Component Analysis (ICA).…”

How the physical similarity of avatars can influence the learning of emotion regulation strategies in teenagers. Computers in Human Behavior. 43:101-111. doi:10.1016/j.chb.2014 How the physical similarity of avatars can influence the learning of emotion regulation strategies in teenagers AbstractThe aim of this study is to evaluate the influence of the physical similarity of avatars with the user on emotion regulation strategy training. In this study twenty-four teenagers observed an avatar (either physically similar to the participant or neutral) that gets frustrated with his/her computer, after which he/she applies an emotion regulation strategy (slow breathing). The intensity of the emotional induction and regulation processes was measured using questionnaires and electroencephalogram data. The results show that observing an avatar that is physically similar to the participant has a significantly greater impact on emotional valence and arousal in participants and also induces emotional states that are significantly more intense than when observing a neutral avatar. The results seem to indicate significantly greater activation of specific brain regions that are related to these processes and greater identification with the avatar in terms of both subjective and objective measures in participants that observed an avatar that was physically similar to them. However, there were no significant differences in the sense of presence or the appeal (i.e., satisfaction) to participants regarding the virtual environment. The use of avatars in mental health applications is relatively new and its specific influence is still unknown. We consider this study to be a first step forward in better understanding the use of avatars in mental health applications for youth. This research brings new guidelines to the design of different types of applications in this field in order to achieve greater behavioral changes in youth.

“…The higher increase in spatial presence observed in children can have its origin on the fact that their frontal cortex function is not fully developed. Recently, preliminary results from a study to analyze the parietal activity in interactive VR were presented [121]. The goal of the study was to analyze if the parietal activity that was found in the study from Baumgartner et al [16] would also appear during a free navigation in a virtual environment.…”

“…Although fMRI and EEG had already been used in previous studies to study presence during the exposure to VE [118,16,121,126,17,18], in this work an alternative brain activity measurement technique (TCD) that has never been used before in conjunction with virtual environments has been proposed. TCD constitutes a complementary neuroimaging tool to measure cerebral perfusion changes due to neural activation and has been 207 widely used to monitor hemodynamic variations in brain activity during the performance of cognitive tasks [20].…”
