Simulation is the creation of an artificial environment for the operation of any process or the imitation of a sequence. The realistic imitation of actual processes or systems provides advantages in terms of time-saving, economic gains, and prevention of major accidents. Simulation is a technique in which a theoretical or physical real system is modeled in a computer environment, and with this model, it is possible to understand the behavior of the system or to evaluate different strategies by means of a computer.
With simulation, any event can be imitated in an identical reality by programming real-world systems and processes and moving them to an artificial environment. Simulators, on the other hand, are computer software, programmed to show the way real-life events play out with different devices.
Simulations can be divided categorized into physical, method, procedural, and functional simulations.
• In physical simulations, a computer-based physical object or phenomenon is represented on the screen. It is widely preferred in the field of education.
• Method simulations are confused with physical simulations in providing information about an event. Method simulations are used to present a method or general idea about situations and events in which indecision is experienced.
• Procedural simulation aims to learn the consequences of the events that make up a procedure. Sparsity in performance, diagnosing a malfunctioning material, or landing a space shuttle are common studies in procedural simulation.
• Functional simulations aim to bring people in different positions to come to a consensus on their behaviors and opinions.

AUGMENTED REALITY
Technological activities in the current age bring along many innovations. One of these innovations is Augmented Reality (AR) technology, which has been studied and practiced in many fields and is becoming more and more involved in our lives day by day. Augmented Reality is formed by virtually superimposing information layers and virtual components on existing real objects or environments. AR is often confused with virtual reality. However, augmented reality, unlike virtual reality (VR), does not create artificial environments to replace the virtual. In other words, VR aims to carry reality over the virtual world, while augmented reality (AR) focuses on enriching the concept of reality with virtual information. Augmented reality can be defined as the superimposition of virtual objects on real images by utilizing the object recognition feature of the necessary devices in an existing environment. The purpose of augmented reality is to strengthen the perception of the users and to add a piece of numerical information to the information obtained with the perception of physical reality regarding the target location, structure, or objects, aiming to provide users with more details about the subject. In other words, augmented reality is a virtual reality application in which users interact with virtual objects while interacting with the real world without affecting the real world. It is one of the latest technologies that digitally enriches our real world and contains meaningful content that facilitates our daily life.
With the augmented reality technology, information about the objects we see around us is brought before the user with texts, pictures, videos, and three-dimensional (3D) objects prepared in the virtual environment. The user, looking at real objects with the help of a camera, special glasses, or a smartphone, sees virtual objects superimposed on those real objects. In this way, it is possible to access and communicate with written and visually enriched information and virtual objects. Virtual objects, which are not visible when observed normally, are perceived differently when viewed with cameras and smartphones. Augmented Reality is discussed technologically in two basic categories. These are optical-based technologies and video-based technologies. The main difference between optical and video-based technologies is where the scene formed by the integration of the real and virtual worlds is seen. The integrated scene in optical systems is displayed on a computer, tablet, or mobile device. Optical-based systems enable users to see the real world together with the virtual world, with the help of devices such as glasses that users place on their heads and wear.
Augmented Reality combines virtual and real environments to provide users with experiences beyond imagination. Augmented Reality technology varies according to development purposes, and at the same time, there are varieties according to the area and the platform used.
Projection-Based AR: The projection-based AR application developed with smartphones basically works on the principle of reflecting the AR functions it contains onto objects. With the projection-based AR, an interactive keyboard, phone dialer, or another interface can be projected onto a specified object at a level where you can use it with your fingers. Reflection-based AR technology is intended to be used in depth and distance measurements of objects.
Marker-Based AR: The marker-based AR, on the other hand, provides information about objects. The basic working principle of marker-based AG is that when predefined markers (such as QR codes and images) in the program are shown to the camera, it identifies and sharpens the distance between them. Then, 2D or 3D objects are generated with the defined markers. Meanwhile, the 3D object rotates simultaneously with the rotation of the marker. Examples of marker-based AR applications are translating foreign words or sentences in the air, defining objects that are difficult to understand in the educational field and explaining them with 3D animations, and showing the architectural projects drawn in different programs in 3D.
Location-Based AR: Being more easily compatible with smartphones and tablets, Location-Based AR is one of the most widely used application types in its field. With Location Based AR, the location can be determined. It determines the location with the help of GPS, compass, and speed measurement modules of smartphones and then transfers the location to the location scanners via the camera on the determined object.
Outline-Based AR: Sometimes, there may be situations that human eye cannot distinguish, due to environmental factors. For such situations, outline-based AR applications are used, which can provide information to the user by using the camera from different angles and drawing some outlines. For example, it can become almost impossible to detect road signs while driving due to bad weather conditions. In order to avoid such situations, advanced cameras can define these signs in an outline framework with the help of AR applications and make them visible to the driver.
Multimedia Based Fully Positioned AR: It works on the principle that the object to be displayed in 3D is displayed precisely positioned on the marker and supported by multimedia objects.
From education to the military field, modern and rational solutions are preferred.
Use of augmented reality in the military: The aim of using augmented reality in the military field is to give the personnel experience with challenging tasks in personnel training, to provide clues about targets and to facilitate target detection.
An example of the use of augmented reality in the military field is the military training application for fighter pilots. With this technology, transparent screens placed on the helmets of fighter pilots and used at eye level instantly show the pilots instant flight data. It is aimed for pilots to see the real image and the data screen at the same time through the transparent screens.
Use of augmented reality in the field of education: Contrary to classical learning methods, augmented reality is a more interactive and memorable technology in which users participate. Augmented reality technology adds a third dimension to two-dimensional books. In physics, chemistry and biology, augmented reality technology is utilized for 3D representation of concepts or performing experiments, visualization of concepts and spatial relationships in courses such as mathematics and geometry, visualization of concepts in geography education, and gaining knowledge and skills about tools and materials.
