While technical compliance with WCAG is well-established, knowledge of User Experience (UX) evaluation methods tailored to non-visual interaction is fragmented. This paper presents a systematic mapping of the literature (2016–2026), analyzing 18 high-quality studies selected from 134 records retrieved from IEEE Xplore, ACM DL, SpringerLink, and ScienceDirect. Results show that user testing is the predominant method, often combined with standardized questionnaires like SUS and NASA-TLX. However, critical gaps persist: small sample sizes, inconsistent participant reporting, and a lack of metrics designed for non-visual interaction. This study contributes a taxonomy of visually impaired user profiles and identifies the technical requirements for building an inclusive web usability laboratory. By bridging the gap between technical auditing and real-world user satisfaction, this work provides a roadmap for the development of the MEUX LAB, ensuring more equitable digital evaluation environments.
