Virtual environments have been developing for a long time and are changing the understanding of a space by means of how we design, perceive and use it. This new understanding of space requires people to adapt by gaining a new type of spatial cognition that can help people to combine the possibilities of a virtual space with the physical space they are used to: by making use of their different sensory skills. The aim of this study is to contribute to the literature on the improvement of the auditory perception and cognition of virtual spaces used for education, training, and gaming purposes. This study proposes to offer a realistic representation of soundscapes in virtual environments according to spatial qualities instead of misleading synthetic sounds by integrating acoustical simulations with the immersive environment and questioning the experience of a regular user. The objectives of this study include: Exploring the virtual environments and soundscape approach in the form of a literature review, Combining the design, cognition, and perception of virtual acoustic environments with Schafer’s soundscape idea, Comparing and understanding the effects of acoustically simulated and immersive virtual soundscape design methods on auditory perception through changing forms and materials by series of cognitive experiments. The results revealed that the participants achieve more accurate results of source-localization, self-localization, and distance guessing in an immersive environment than in the simulated environment. In addition, they were more aware of the soundwalk route, spent more time on tasks, and evaluated the experience more positively in an immersive environment compared to simulations. Despite the placement of the auralizations from the simulations as sound sources in tested immersive environments, there is still a lack of auditory representation of spatial qualities compared to the accurate calculation of acoustical parameters in a simulated environment.

Performance Models for the Spike Banded Linear System Solver Manguoğlu, Murat; Sameh, Ahmed; Grama, Ananth (Hindawi Limited, 2011) With availability of large-scale parallel platforms comprised of tens-of-thousands of processors and beyond, there is significant impetus for the development of scalable parallel sparse linear system solvers and preconditioners. An integral part of this design process is the development of performance models capable of predicting performance and providing accurate cost models for the solvers and preconditioners. There has been some work in the past on characterizing performance of the iterative solvers them...
Immersive design environments for performative architectural design: a BIM-based approach. Akın, Şahin; Gürsel Dino, İpek; Department of Architecture (2020) In architectural design processes, the use of shared, simulated, and synchronized virtual environments and computational methods becomes widespread. Virtual reality immerses users in a three-dimensional digital environment and has the potential to make them involve actively in the act of design. Daylighting is an essential concept in architectural design, but its assessment and integration to the design process can be complicated. The use of Building Information Modelling (BIM) tools is identified as a crit...
Multiverse of a Form Sorguç, Arzu; Özgenel, Çağlar Fırat (2018-09-21) The almost seamless integration of computation, fabrication and immersion technologies in architecture not only constitutes potentials for exploring design instances through multiple media but also changes design paradigm from form-formation to form-formation-exploration. In this sense, multiverse of design as proposed in this study and integration of various design technologies from virtual to real aims to advance higher-order thinking skills and a more exclusive design exploration in computational design ...
Sayısal Ortamda, Tasarımın Deneyimlenmesi İçin Arayüzlerin Geliştirilmesi: Bir Ön-Tasarım Parametresi Olarak Ses Özgenel, Çağlar Fırat; Sorguç, Arzu (2011-01-01) In architecture of our day, with the enhancement in technology, experiencing design decisions and / or changes by means of various computational technologies in computational medium has become an essential design tool. With the presence of the tools used in computational medium, changes in the architectural design process occurred and the usage of the tools drifted from simply virtual experience to optimization of the design by examining the design throughout the process. In the performance based design app...
Architectural Design in Virtual Reality and Mixed Reality Environments: A Comparative Analysis Ergün, Oğuzcan; Akın, Şahin; Gürsel Dino, İpek; Sürer, Elif (2019-01-01) Virtual reality (VR) provides a completely digital world of interaction which enables the users to modify, edit, and transform digital elements in a responsive way. Mixed reality (MR), which is the result of blending the digital world and the physical world together, brings new advancements and challenges to human, computer and environment interactions. This paper focuses on adapting the already-existing methods and tools in architecture to both VR and MR environments under sustainable architectural design ...
