Luciole, a new font for people with low vision

Area of Science:

• Ophthalmology
• Cognitive Science
• Typography

Background:

• Low vision significantly impedes educational and professional opportunities due to reading difficulties.
• Developing accessible reading tools is crucial for improving quality of life for visually impaired individuals.

Purpose of the Study:

• To evaluate the effectiveness of a newly designed font, Luciole, in improving reading comfort and readability for people with low vision.
• To compare the performance of the Luciole font against five established fonts (Arial, OpenDyslexic, Verdana, Eido, Frutiger).

Main Methods:

• A study involving 145 French readers (73 with low vision, 72 normal-sighted), aged 6-35, across four reading expertise levels.
• Participants performed two tasks: reading on paper and reading false-words on screen, utilizing eye-tracking technology.
• Subjective preferences and objective readability metrics were collected for each font.

Main Results:

• Approximately 50% of low-vision participants expressed a preference for the Luciole font in both paper and screen-based reading tasks.
• The Luciole font demonstrated a slight readability advantage over certain fonts like Eido and OpenDyslexic for both low-vision and normal-sighted groups.
• Analysis considering reading expertise levels corroborated the observed trends, indicating consistent performance benefits.

Conclusions:

• The Luciole font shows promise as a tool to enhance reading accessibility and comfort for individuals with low vision.
• Font design plays a significant role in readability, particularly for populations facing visual challenges.
• Further research into specialized typography can contribute to inclusive educational and workplace environments.
