Flight simulator systems generally use a separate image-generator component. The host is responsible for the positional data updates of the entities and the image generator is responsible for the rendering process. In such systems, the sense of presence is decreased by model flickering. This study presents a method by which the host can minimize model flickering in the image-generator output. The method is based on preexisting algorithms, such as visibility culling and level of detail management of 3D models. The flickering is minimized for the visually important entities at the expense of increasing the flickering of the entities that are out of the user's focus using a new perception-based approach. It is shown through user studies that the new proposed approach increases the participants' sense of presence.

Towards interoperable and composable trajectory simulations: an ontology-based approach Durak, U.; Oğuztüzün, Mehmet Halit S.; Algin, C. Koksal; Ozdikis, O. (Informa UK Limited, 2011-08-01) Trajectory simulation is a software module that computes the flight path and flight parameters of munitions. It is used throughout the engineering process, including simulations for studying the design trade-offs, to mission simulations for defended area analysis. In this wide application domain, reuse has always been one of the challenges of the trajectory simulation community. We apply an ontology-based simulation development methodology to fulfil the functional requirements of a trajectory simulation whi...
Exploring the effects of working memory capacity, attention and expertise on situation awareness in a flight simulation environment Özcan, Orçun Orkan; Çakır, Murat Perit; Say, Bilge; Department of Cognitive Sciences (2012) Experienced and novice simulator pilots are subject to some of the constraints of a real flight (or a full flight simulator) situation in a PC based flight simulation. In this thesis, the effects of expertise, working memory capacity, inhibition and divided attention on situation awareness (SA) in simulated flight task environments are investigated. The cognitive aspects underlying the process of situation awareness are explored by analyzing the compound effects of above listed factors. Online and Offline S...
Coordinate systems for a naval virtual environment Kılıç, Aslı; Oğuztüzün, Mehmet Halit S.; Department of Computer Engineering (2005) The purpose of this thesis is implementing World Geodetic System (WGS) for Naval Surface Tactical Maneuvering Simulation System (NSTMSS), a High Level Architecture (HLA) based naval simulation, and also implementing body coordinate system for the ships of NSTMSS and its combination with WGS so that NSTMSS can be more accurate, and new ship dynamics models can be integrated to the NSTMSS environment more easily. To improve the coordinate system of NSTMSS these methods were used; World Geodetic System - 1984 ...
Enhancing positioning accuracy of GPS/INS system during GPS outages utilizing artificial neural network Kaygisiz, Burak H.; Erkmen, Aydan Müşerref; Erkmen, İsmet (Springer Science and Business Media LLC, 2007-06-01) Integrated global positioning system and inertial navigation system (GPS/INS) have been extensively employed for navigation purposes. However, low-grade GPS/INS systems generate erroneous navigation solutions in the absence of GPS signals and drift very fast. We propose in this paper a novel method to integrate a low-grade GPS/INS with an artificial neural network (ANN) structure. Our method is based on updating the INS in a Kalman filter structure using ANN during GPS outages. This study focuses on the des...
Exploring the Effects of Working Memory Capacity Attention and Expertise on Situation Awareness in a Flight Simulation Environment Özcan, Orkan; Çakır, Murat Perit; Say, Bilge (null; 2013-05-06) Simulator pilots are subject to some of the constraints of a real flight situation in a PC based flight simulation. Situation awareness (SA) for simulator pilots was explored in terms of underlying cognitive aspects by analyzing the compound effects of expertise, working memory, inhibition and divided attention. Online and Offline SA measurements were analyzed with expertise and scores of Automated Operation Span Task, Stroop and Coşkunöz visual attention tasks. Regression analyses revealed the expected rel...
