abstract = {In crisis situations, illiterates and people with other linguistic challenges are unable to understand text messages to inform or be informed of a situation. Pictographic interfaces have been proposed as a solution for empowering these marginalized and vulnerable populations, including elderly, people with disabilities, and foreigners. In this paper, we follow up on previous work and investigate the comprehensibility and appropriateness of prototypical complex alerting and reporting pictographs. We present results of a field study with illiterate people in Sri Lanka and the Philippines. We show that complex representations can very well be understood with respect to incident and severity, especially if context objects are shown. Additionally, we identify several aspects where further research is needed. We discuss the findings and propose further steps towards designing pictograph-based communication, especially on mobile devices.},

abstract = {This article describes how pictographs (or pictograms) can be an important means to communicate information about natural disasters to people that are lacking the capability to understand written text. This does not only include illiterates, but also foreigners not speaking the local language. While it is widely accepted that pictograph-based communication can play a major role, there is no established workflow to include this kind of symbols in early warning or disaster reporting practice. This article investigates the topic of pictograph-based communication systems, especially in the field of natural disasters, with a focus on the use of linguistically challenged populations. The authors analyze existing literature, take a look at existing pictograph resources, analyze a first field study with marginalized populations and derive conclusions for a design process for pictograph-based disaster communication systems.},
