Museums want to be inclusive. But when it comes to visual art, "accessible" usually means a ramp at the entrance. Not a meaningful experience for blind and partially sighted visitors. I ran three research studies across 20 weeks to find out: can art experts and non experts create artwork descriptions good enough to actually serve blind and partially sighted users? And what guidelines would make that possible at scale? Methods: Delphi method, semi-structured interviews, statistical analysis (Friedman's ANOVA, Wilcoxon tests). Participants: 18 art professionals, 10 blind/partially sighted users, 23 members of the public. Outcome: Evidence-based guidelines adopted as a framework for museum description programmes
