Modelling, simulation and auralisation of room acoustics plays an important role in computer games and virtual reality applications by increasing the level of realism. Accurate simulation of room acoustics is a computationally costly process which is often substituted with artificial reverberators that provide a computationally simpler alternative. However, such systems lack the accuracy and are not in general able to accurately simulate important aspects of room acoustics such as early reflections, source/microphone directivity, and frequency-dependent absorption. A new type of interactive and scalable room simulator named the scattering delay network (SDN) was recently proposed by the authors. A frequency-domain analysis and implementation of that simulator is presented in this paper. Numerical simulation examples which demonstrate the utility of the proposed system are provided.

Effects of color-multiplex stereoscopic view on memory and navigation Baanlar, Yalin; Canuere, Deniz; Karacan, Hacer (2007-05-09) In this work, effects of stereoscopic view on object recognition and navigation performance of the participants are examined in an indoor Desktop Virtual Reality Environment, which is a two-floor virtual museum having different floor plans and 3D object models inside. This environment is used in two different experimental settings: 1) color-multiplex stereoscopic 3D viewing is provided by colored eye-wear, 2) regular 2D viewing. After the experiment, participants filled a questionnaire that inquires their f...
Scattering delay network an interactive reverberator for computer games Enzo, De Sena; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2011-02-02) Many 3D computer games incorporate audio renderers simulating room acoustics to provide the user with a high level of immersiveness and realism. Full-scale interactive room auralisation systems are impractical for use in computer games due to their high computational cost. As a low-cost alternative, artificial reverberators can be used. This paper is concerned with the design of a scalable interactive reverberator inspired by digital waveguide mesh (DWM) models and feedback delay networks (FDN). This reverb...
Developing building information modelling based virtual reality and mixed reality environments for architectural design and improving user interactions with serious games Ergün, Oğuzcan.; Sürer, Elif; Department of Modeling and Simulation (2019) Virtual Reality (VR) provides an interactive experience for its users in a fully artificial computer-simulated environment while Mixed Reality (MR) forms environments by mixing the real world and the virtual world elements together. In the first part of this thesis, an architectural visualization and design tool, which is based on Building Information Modeling (BIM), is developed for VR, MR and personal computer (PC) environments. BIM provides detailed information and tools to professionals so that they can...
Scattering delay networks with aperture size control for simulating coupled volume acoustics Atalay, Timuçin Berk; Hacıhabiboğlu, Hüseyin; Department of Modeling and Simulation (2019) Artificial reverberators provide a computationally viable alternative to full-scale room acoustics simulation methods when used in interactive, immersive systems. Scattering delay network (SDN) is a relatively recent artificial reverberator that allows direct parametric control over the geometry of a simulated rectangular enclosure as well the directional characteristics of the simulated sound sources and microphones. Coupled volume SDN aims to extend the SDN structure for enclosures coupled via an aperture...
Usability of virtual reality for basic design education: a comparative study with paper-based design Özgen, Dilay Seda; Afacan, Yasemin; Sürer, Elif (SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS, 2019-11) Virtual reality (VR) is an emerging technology that is being used in a wide range of fields such as medicine, gaming, psychology and sociology. The use of VR is promising in the field of education and requires investigation, but research on the use of VR in education is still limited. This enables the exploration of new territories, and design education is one of them. Design education, an important part of the curriculum of architecture students who aim to conceptualize problem-solving, is still taught usi...
