Available in PDF, EPUB and Kindle. Book excerpt: It is well documented that within Virtual Environments performance in cognitive tasks is diminished, and with the continued use of such environments to train people in various skillsets it is important that this problem be addressed. In this thesis, two areas of spatial cognition are addressed: navigation and distance estimation. Unlike many previous studies, the experiments conducted here are in a large-scale virtual rural environment which poses problems due to the large distances involved and the unrestricted movement of people through it. A virtual representation of the Sorbas region in Spain was produced using Blueberry3D, VegaPrime and ArcMap. Attempts to improve performance were made by the display of information to the user: an overview map to aid in distance estimations; and geo-located 'factoids', or info-marks, to aid in navigation. Analysis was also performed to extract rural environment features that could fall into the classifications of the Urban Image Theory, and a novel visio-analytic approach conducted to analyse track log data collected from the navigation task. Results indicate that neither of the two tools implemented had much effect on user performance. However, a key finding was that the use of both quantitative and qualitative analysis is important in such research, as although quantitative analysis indicated only some significant results, the qualitative analysis highlighted that when the tools were presented users felt far more confident in their results. The visio-analytical approach adopted proved to be extremely useful in identifying performance characteristics that would have been missed by using quantitative analysis alone.

Available in PDF, EPUB and Kindle. Book excerpt: With contributions from a collection of authors consisting of many recognizable experts in the field of virtual and adaptive environments, as well as many up and coming young researchers, this book illustrates the many ways in which psychological science contributes to and benefits from the increased development and application of these nascent systems. Discussing issues from both a user- and technology-based standpoint, the volume examins the use of human perception, cognition, and behavior. The book builds a foundation on the assumption that these systems are first and foremost human-centered technologies, in that their purpose is to complement and extend human capabilities across a wide variety of domains.

Download or read book Spatial Multimedia and Virtual Reality written by Antonio S. Camara and published by CRC Press. This book was released on 2021-04-30 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intersection of two disciplines and technologies which have become mature academic research topics in the 1990s was destined to be a dynamic area for collaboration and publication. However, until now no significant book-length treatment of the meeting of GIS and Virtual Reality has been available. This volume puts that situation to rights by bringing these together to cement some common understanding and principles in a potentially highly promising area for technological collaboration and cross-fertilisation. The result is a volume which ranges in subject matter from studies of a Virtual GIS Room to Spatial Agents, and from an Environmental Multimedia System to Computer-Assisted 3D Geographic Education. All the contributors are well-known international scientists, principally from the computational side of GIS. It will be a valuable resource for any GIS researcher or professional looking to understand the leading edge of this fertile field.

This book was released on 2000 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immersive simulation techniques such as Virtual Environments (VE) can revolutionize human factors engineering and training projects provided that they are carefully validated. Is human performance in the virtual world the same as in the real world? When visual aspects perceived on a virtual ship differ from those perceived on a real ship, human factors engineering studies may yield non-optimal designs When interactions with virtual worlds are not natural, training may not transfer to the real world. I will discuss three studies that compared human task performance in real and virtual (HMD) environments. First, we carried out spatial perception experiments and measured localization performance: how well can people indicate the center point between two objects in identical virtual and real environments. Second, manipulation performance was measured: how well can people grab, turn and position objects in virtual environments and what adaptation effects occur when returning to the real world. Third, we compared the assessment of ergonomic aspects of identical virtual and real ship bridges. Discrepancies found between the results for the real and the virtual bridge are discussed in terms of challenges with respect to the quality of head-mounted display optics and tracking devices and, most importantly, with respect to natural interfaces needed for manipulation (virtual hand control) and for moving around in virtual worlds (intuitive navigation methods).

Download or read book The Effect of Presence on the Ability to Acquire Spatial Knowledge in Virtual Environments written by David Bernatovich and published by . This book was released on 1999-09-01 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is unclear what impact presence has on a virtual environment's (VE) ability to enhance learning and performance. Currently, there are many theories and conjectures about the effects of presence in VEs. To better the effectiveness of VEs, it is imperative that we determine the impact, both positive and negative, of presence on our ability to perform in VEs. Therefore, we must study how presence affects a person' ability to acquire skills and knowledge. This must include our ability to navigate and perform spatial tasks as well as any other aspect of the real world that may be represented by a VE. To begin understanding how presence affects performance, forty individuals participated in an experiment to determine how presence affects the ability to acquire spatial knowledge in a VE. The purpose of the experiment was to determine if the level of presence in a VE increased or decreased a person's ability to acquire spatial knowledge, to include landmark recognition, procedural knowledge, and survey knowledge. Each participant received one of the following VE treatments: (1) No Sound, (2) Verbal cues with topical information, (3) Verbal cues with spatial information, or (4) a Combination of both topical and spatial information. They were then administered a series of spatial tests. Finally, they were given a presence questionnaire to measure their self assessed level of presence. The results indicate that as the level of presence in the VE varies, there is no effect on a person's ability to acquire spatial knowledge. A person's spatial performance is more likely the result of their innate spatial abilities and visual memory. Additionally, including non-specialized sound in a VE increased the reported level of presence by 15.1 percent. When that sound was exclusively related to the primary task the level of presence increased by 17 percent. Finally, the inclusion of non-specialized sound has no affect on the ability to perform spatial tasks.

Download or read book Automated Generation of Geometrically Precise and Semantically Informed Virtual Geographic Environments Populated with Spatially Reasoning Agents written by Mehdi Mekni and published by Universal-Publishers. This book was released on 2010-10-29 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-Agent Geo-Simulation (MAGS) is a modelling paradigm which has attracted a growing interest from researchers and practitioners for the study of various phenomena in a variety of domains such as traffic simulation, urban dynamics, environment monitoring, as well as changes of land use and cover, to name a few. These phenomena usually involve a large number of simulated actors (implemented as software agents) evolving in, and interacting with, an explicit spatial environment representation commonly called Virtual Geographic Environment (VGE). Since a geographic environment may be complex and large-scale, the creation of a VGE is difficult and needs large quantities of geometrical data originating from the environment characteristics (terrain elevation, location of objects and agents, etc.) as well as semantic information that qualifies space (building, road, park, etc.). CurrentMAGS approaches usually consider the environment as a monolithic structure, which considerably reduces the capacity to handle largescale, real world geographic environments as well as agent's spatial reasoning capabilities. Moreover, the problem of path planning in MAGS involving complex and large-scale VGEs has to be solved in real time, often under constraints of limited memory and CPU resources. Available path planners provide agents with obstacle-free paths between two located positions in the VGE, but take into account neither the environment's characteristics (topologic and semantic) nor the agents' types and capabilities. In addition, agents evolving in a VGE lack for mechanisms and tools that allow them to acquire knowledge about their virtual environment in order to make informed decisions. In this thesis, we propose a novel approach to automatically generate a semantically-enriched and geometrically-precise representation of the geographic environment that we call Informed Virtual Geographic Environment (IVGE). Our IVGE model efficiently organizes the geographic features, precisely captures the real world complexity, and reliably represents large-scale geographic environments. We also provide a new hierarchical path planning algorithm which leverages the enriched description of the IVGE in order to support agents' reasoning capabilities while optimising computation costs and taking into account both the virtual environment's characteristics and the agents' types and capabilities. Finally, we propos an environment knowledge management approach to support the agents' spatial decision making process while interacting with the IVGE.

Download or read book Cognitive and Linguistic Aspects of Geographic Space written by Martin Raubal and published by Springer Science & Business Media. This book was released on 2013-01-30 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: 20 years ago, from July 8 to 20, 1990, 60 researchers gathered for two weeks at Castillo-Palacio Magalia in Las Navas del Marques (Avila Province, Spain) to discuss cognitive and linguistic aspects of geographic space. This meeting was the start of successful research on cognitive issues in geographic information science, produced an edited book (D. M. Mark and A. U. Frank, Eds., 1991, Cognitive and Linguistic Aspects of Geographic Space. NATO ASI Series D: Behavioural and Social Sciences 63. Kluwer, Dordrecht/Boston/London), and led to a biannual conference (COSIT), a refereed journal (Spatial Cognition and Computation), and a substantial and still growing research community. It appeared worthwhile to assess the achievements and to reconsider the research challenges twenty years later. What has changed in the age of computational ontologies and cyber-infrastructures? Consider that 1990 the web was only about to emerge and the very first laptops had just appeared! The 2010 meeting brought together many of the original participants, but was also open to others, and invited contributions from all who are researching these topics. Early-career scientists, engineers, and humanists working at the intersection of cognitive science and geographic information science were invited to help with the re-assessment of research needs and approaches. The meeting was very successful and compared the research agenda laid out in the 1990 book with achievements over the past twenty years and then turned to the future: What are the challenges today? What are worthwhile goals for basic research? What can be achieved in the next 20 years? What are the lessons learned? This edited book will assess the current state of the field through chapters by participants in the 1990 and 2010 meetings and will also document an interdisciplinary research agenda for the future.

Available in PDF, EPUB and Kindle. Book excerpt: Learning to Think Spatially examines how spatial thinking might be incorporated into existing standards-based instruction across the school curriculum. Spatial thinking must be recognized as a fundamental part of Kâ€"12 education and as an integrator and a facilitator for problem solving across the curriculum. With advances in computing technologies and the increasing availability of geospatial data, spatial thinking will play a significant role in the information-based economy of the twenty-first century. Using appropriately designed support systems tailored to the Kâ€"12 context, spatial thinking can be taught formally to all students. A geographic information system (GIS) offers one example of a high-technology support system that can enable students and teachers to practice and apply spatial thinking in many areas of the curriculum.
