Spatial cognition in virtual environments

Since the last decades of the past century, Virtual Reality (VR) has been developed also as a methodology in research, besides a set of helpful applications in medical field (trainings for surgeons, but also rehabilitation tools). In science, there is still no agreement if the use of this technology in research on cognitive processes allows us to generalize results found in a Virtual Environment (VE) to the human behavior or cognition in the real world. This happens because of a series of differences found in basic perceptual processes (for example, depth perception) suggest a big difference in visual environmental representation capabilities of Virtual scenarios. On the other side, in literature quite a lot of studies can be found, which give a proof of VEs reliability in more than one field (trainings and rehabilitation, but also in some research paradigms). The main aim of this thesis is to investigate if, and in which cases, these two different views can be integrated and shed a new light and insights on the use of VR in research. Through the many experiments conducted in the "Virtual Development and Training Center" of the Fraunhofer Institute in Magdeburg, we addressed both low-level spatial processes (within an "evaluation of distances paradigm") and high-level spatial cognition (using a navigation and visuospatial planning task, called "3D Maps"), trying to address, at the same time, also practical problems as, for example, the use of stereoscopy in VEs or the problem of "Simulator Sickness" during navigation in immersive VEs. The results obtained with our research fill some gaps in literature about spatial cognition in VR and allow us to suggest that the use of VEs in research is quite reliable, mainly if the investigated processes are from the higher level of complexity. In this case, in fact, human brain "adapts" pretty well even to a "new" reality like the one offered by the VR, providing of course a familiarization period and the possibility to interact with the environment; the behavior will then be “like if” the environment was real: what is strongly lacking, at the moment, is the possibility to give a completely multisensorial experience, which is a very important issue in order to get the best from this kind of “visualization” of an artificial world. From a low-level point of view, we can confirm what already found in literature, that there are some basic differences in how our visual system perceives important spatial cues as depth and relationships between objects, and, therefore, we cannot talk about "similar environments" talking about VR and reality. The idea that VR is a "different" reality, offering potentially unlimited possibilities of use, even overcoming some physical limits of the real world, in which this "new" reality can be acquired by our cognitive system just by interacting with it, is therefore discussed in the conclusions of this work

Haptics: Science, Technology, Applications

This open access book constitutes the proceedings of the 12th International Conference on Human Haptic Sensing and Touch Enabled Computer Applications, EuroHaptics 2020, held in Leiden, The Netherlands, in September 2020. The 60 papers presented in this volume were carefully reviewed and selected from 111 submissions. The were organized in topical sections on haptic science, haptic technology, and haptic applications. This year's focus is on accessibility

Design revolutions: IASDR 2019 Conference Proceedings. Volume 2: Living, Making, Value

In September 2019 Manchester School of Art at Manchester Metropolitan University was honoured to host the bi-annual conference of the International Association of Societies of Design Research (IASDR) under the unifying theme of DESIGN REVOLUTIONS. This was the first time the conference had been held in the UK. Through key research themes across nine conference tracks – Change, Learning, Living, Making, People, Technology, Thinking, Value and Voices – the conference opened up compelling, meaningful and radical dialogue of the role of design in addressing societal and organisational challenges. This Volume 2 includes papers from Living, Making and Value tracks of the conference

Unmet goals of tracking: within-track heterogeneity of students' expectations for

Educational systems are often characterized by some form(s) of ability grouping, like tracking. Although substantial variation in the implementation of these practices exists, it is always the aim to improve teaching efficiency by creating homogeneous groups of students in terms of capabilities and performances as well as expected pathways. If students’ expected pathways (university, graduate school, or working) are in line with the goals of tracking, one might presume that these expectations are rather homogeneous within tracks and heterogeneous between tracks. In Flanders (the northern region of Belgium), the educational system consists of four tracks. Many students start out in the most prestigious, academic track. If they fail to gain the necessary credentials, they move to the less esteemed technical and vocational tracks. Therefore, the educational system has been called a 'cascade system'. We presume that this cascade system creates homogeneous expectations in the academic track, though heterogeneous expectations in the technical and vocational tracks. We use data from the International Study of City Youth (ISCY), gathered during the 2013-2014 school year from 2354 pupils of the tenth grade across 30 secondary schools in the city of Ghent, Flanders. Preliminary results suggest that the technical and vocational tracks show more heterogeneity in student’s expectations than the academic track. If tracking does not fulfill the desired goals in some tracks, tracking practices should be questioned as tracking occurs along social and ethnic lines, causing social inequality
