Accessible signage and augmentative communication in public works for inclusive cities and communicative literacy

Abstract

In an increasingly urbanized world, accessible signage and augmentative communication become vital tools to create cities that include everyone, regardless of visual, cognitive, or motor disabilities. This article examines how these practices integrate into public works, promoting communicative literacy that empowers marginalized people to navigate and participate in urban spaces. Through a systematic review of recent studies, designs of signs for older adults in hospitals are analyzed, where size and contrast improve understanding and reduce confusion. The use of pictograms in emergencies like Covid-19 is addressed, with strategic placement and colorful graphics effectively transmitting prevention. Eye-tracking in constructions is highlighted, showing intense colors and simple shapes optimizing retention and minimizing risks. Additionally, inclusive frameworks encompassing cultural diversity and equity are discussed, inspired by audits of built environments for universal design. The author believes these innovations not only prevent accidents but also strengthen social bonds by making cities empathetic. Finally, urban policies focused on sustainability and inclusion are proposed, transforming public works into connectors towards fair societies.
