Ux Design Guideline For Health Mobile Application To Improve Accessibility For The Visually Impaired Focusing On Disease Retinitis Pigmentosa

A Health Mobile Application (App) has enabled users to access personal health record at any time and place. As an App provides health service to users, it is crucial for an App to be accessible to every user. However, it is often an App does not provide proper visual aid for users who are visually impaired. We restrict the range of visually impaired to retinitis pigmentosa (RP) patients in this paper. RP is a rare type of progressive retinal disease which is hard to cure. Unfortunately, there are no established guidelines to assist RP patients in using their degrading sense of vision. In this paper, we review MWAG(Mobile Web Accessibility Guidelines) specified by W3C and analyze the UX designs of 140 popular health apps chosen based on the number of download counts in app stores and we propose a set of standard-compliant UX design guidelines to assist the visually impaired(RP) in accessing visual data and evaluate its compliance compared to MWAG.
