Standardization of "Dynamic Sign" for Comfort and Safe Society

Animated signs and signs that changed according to the situation, can be expected to improve the convenience of facilities and improve safety and security concerning traffic. This technology is already being developed in multiple countries, and some practical applications have already been realized. Most of these consist of projection lighting systems for presenting information in public spaces. In this paper, this technology will be referred to as "Dynamic sign." However, the significance, necessity and feasibility of "Dynamic sign" has been recognized, there are currently no international standards that describe the ergonomic requirements for designing "Dynamic sign." To spread this new technology of "Dynamic sign" through the marketplace quickly and appropriately, it is important to avoid situations with competing specifications that do not take into account the cognitive characteristics of the information recipient. Accordingly, this paper discuss the first step of the human ergonomics principles for the application of "Dynamic sign."
