# Holographic Mixed Reality System for Air Traffic Control and Management
## 7 Conclusions  
Thus far, the application of research and development MR technology has only concentrated on one field, such as entertainment. However, seeing the necessity of MR technology in the operating environment of real equipment, this study proposed a future type air traffic control system using MR technology. That is, the attempt to apply this technology in a complex work environment such as ATC/M intended to develop MR technology, which is one of the deriving forces of the fourth industry at the national level, is very meaningful for the development of related technologies. Therefore, in this study, the characteristics of MR technology are understood, and appropriate interaction methods are designed to propose a system to improve the work efficiency and productivity of air traffic controllers. This system is made to be controlled firsthand by air traffic controllers to provide a measure to give new user experiences. The expected effects that can be obtained from the outcome of the development in this study are as follows. 1. The possibility to use the system as an education and training system: The International Civil Aviation Organization (ICAO) recommends the expansion of simulator education for air traffic controllers because air accidents can be prevented in advance with pre-training by cultivating the ability of air traffic controllers to prevent accidents and cope when accidents have already occurred. In the aviation advanced countries, aerodrome control simulators are introduced, and periodic training is carried out to improve the ability of the air traffic controller to cope with normal and abnormal situations. Reflecting this international trend, the use of this system as an ATC simulator or training tool can help to solve problems to a great extent. 2. The possibility to use the system as a tool to analyze accident sequences: In order to understand the sequence of an accident, it is important to substitute the various unit events and environment conditions and to analyze the accurate causal relations. The survey indicated that air traffic controllers are also called for meetings to analyze accident sequences and trained. The systematic methods or tools are needed to establish preventive measures to prevent the recurrence of accidents and similar causes. The utilization of this as a tool to analyze accident sequences can be expected. 3. The possibility of overcoming control facility constraints: While efforts are being made to replace or add control equipment to solve problems caused by air traffic density increasing every year, there are always financial limitations. Continuous research on the control system is needed to overcome these physical constraints and reduce the probability of safety accidents. This system can reduce the purchase cost inputted in the construction of a new control system and equipment replacement and can be used for support as a complementary tool for control work while performing the main purpose of control work in actual operating environments. 4. The improvement of the work efficiency of air traffic controllers with system integration: Since air traffic control is carried out by air traffic controllers in general, it is important to reduce the complexity of air traffic control. Currently, there are various control systems with the same functions, but providing a vast amount of non-selected information can increase the complexity of air traffic control. This system provides the proper information used by the air traffic controllersafter integrating and selecting proper information. In addition, it supports intuitive interactions such as gestures and voice commands, as well as multiple view and 3D spatial sound functions, which are effective in improving the understanding of information. By selectively providing information that is helpful for control judgments, this system can improve the efficiency of control work, such as reducing the workload of air traffic controllers. 5.
