ABSTRACT
QR codes (Quick Response) are an established tool for quickly sharing digital information, but their use is not automatically accessible to everyone. People with sensory and cognitive disabilities, the blind, visually impaired, deaf, hard of hearing, and people with intellectual disabilities often encounter severe limitations in perceiving, interpreting, or interacting with conventional QR codes. This article discusses Accessible QR codes (AQR) based on the principles of universal design and digital inclusion, which enable universal access to content.
The research is based on a comprehensive combination of a systematic literature review, a conceptual analysis of the needs of three target groups, and a case study of the advanced NaviLens system. The key technological features of AQR codes are presented, such as distance detection, automatic navigation, use of sign language, easy-to-read text, and audio feedback. We also investigated possible manipulations and abuses.
The hypothesis is that AQR codes significantly improve access to information in public spaces and contribute to user independence and inclusion. The concluding part presents guidelines for the implementation of AQR codes in Slovenia, as well as robust protection measures against abuse and recommendations for setting up test environments and pilot projects, ensuring a secure and successful implementation.
