This study is a preparation phase for visualization of utilized information using ergonomic user interface and standardization of elements for anti-air radar screen. Therefore, we investigated the instances of anti-air radar screen for air defense weapon system for defense advanced country. Based on the collected data, we compared and analyzed the air defense weapon system radar screen design. In addition, we carry out a research for layout, configuration, standardization and design of the radar screen’s elements. Ultimately, it is essential to share a variety of battle field conditions such as enemy threat, enemy/friendly information, terrain information that can be effectively recognized. In this paper, we conduct case study for ergonomically development of automated/standardized radar screen. It is expected that this research improves the situational awareness and reduces the user’s task load. 展开更多
