With the aim of reducing human casualties in the event of a disaster, our research group is developing various disaster prevention signs to be used as infrastructure (e.g., JSPS KAKENHI Grant Numbers JP20K03256, JP23K02821). In recent years, Japan has faced an increase in the number of elderly people as well as an increase in the number of inbound visitors due to the depreciation of the yen in many areas. Signs for disaster prevention and mitigation purposes are therefore required to accommodate diverse evacuees of different ages, genders, knowledge, and cultural backgrounds. As one measure, a method is proposed to add textual information to disaster prevention signs to promote understanding of the pictograms shown on the signs. The textual information that should be assigned to a pictogram on a disaster prevention sign depends largely on the characteristics of the target audience (age, nationality, etc.) who will see the sign, as well as on regional characteristics. Therefore, in building a system for Web distribution of disaster prevention signs as an infrastructure, it is preferable to implement a function that allows users who download and post signs to enter any text they wish, rather than implementing a standardized language and character string for the text to be assigned to signs. This study clarifies the requirements for the construction of a web-based distribution system for interactive disaster prevention signs, in which users can add arbitrary character strings to pictograms, and discusses implementation measures and the resulting expected benefits.
