Welcome to Inclusive Reading Technologies.
We are a nonprofit dedicated to improving accessibility and visual readability, and home to the APCA Readability Criterion.
The APCA Readability Criterion (ARC) provides recommendations for making visual content on self-illuminated displays more accessible to all users, especially those with visual impairments.
