A study on design guidelines for the icons used in nuclear power plants

In this project, advantages and disadvantages of icons on electronic displays were analyzed, and design procedures, design evaluation principles, and design guidelines for icons on electronic displays were developed. In addition, as design guidelines for special effects applicable to icons on electronic displays, guidelines for color coding, flashing, and 3-dimensional effects were developed. A questionnaire survey was performed to investigate how NPP operators consider methods representing icons on electronic displays (such as colors, dynamic effects, and 3-dimensional effects) compared to methods representing icons by using outlines in the P and ID drawings. NPP operators' preference of the icons designed in accordance with icon design guidelines to the icons without considering the guidelines was also investigated
