Wayfinding system adapted for people with visual impairments
at the Hôpital des 15-20

As part of the project to redesign the hospital’s wayfinding system, which was entrusted to our studio, our approach involved a critical analysis of so-called “universal” typefaces designed for vulnerable populations and those with disabilities, specifically visual impairments. The existing signage system, which was inconsistent and ill-suited to its visitors and patients, required a comprehensive assessment to identify numerous shortcomings, such as the display of information useful to patients and medical staff, the management of foot traffic, the naming of spaces, and the types of informational media throughout the facility. 

Our approach began with research to validate the choice of a custom typeface, whose design was derived from data collected from a panel of patients. This data was gathered through an innovative visual test hosted by an app. 

This method allowed us to adapt the typographic design to different medical conditions, thereby creating a variable, unique, and custom typeface. The Zed typeface is thus a pragmatic and extremely versatile font designed for information accessibility. Its forms are reduced to the essentials, yet never compromise readability. 

A family of modular signage fixtures (designed for better adaptability to the various spaces and vantage points encountered along the buildings’ interior pathways) made of wood and Krion serves as a support and guiding thread for identifying and directional information. Screen-printed according to the hospital’s color codes, the original typeface and its pictograms appear in generous, high-contrast sizes.
