Game Accessibility Guidelines for People with Sequelae from Macular Chorioretinitis

Abstract

Macular chorioretinitis is an ocular inflammation that may cause the permanent loss of the central vision. Researches indicate that the formation of macular scars, the potential sequelae of that inflammation, is the leading cause of low vision in children. As we found no game accessibility guidelines in the literature that were specific to users with central vision loss in a preliminary search, this study thus aimed at surveying those targeted at players with low vision. The guidelines were extracted through a systematic literature review conducted on digital libraries and also with the manual selection of other relevant sources. In total, we identified 25 more general game accessibility guidelines, for people with low vision, and 19 of them were considered applicable to people with macular scars. Afterward, we assessed the viability of implementing each guideline according to their impact, reach and cost. The survey also confirmed that no guideline existed that was specific to players with central vision loss. We expect the results of this research to serve as a starting point for the definition of new guidelines specific to players with sequelae from macular chorioretinitis.
