Although digital technologies improve the quality of life for people with visual impairment, their influences on social justice are inconclusive. In this study, we use quantitative and qualitative methods to investigate the effect of real-time volunteer apps on prejudice and social connection from the perspective of both visually impaired people (VIPs) and non-impaired people (NIPs). Counterintuitively, our findings suggest that real-time volunteer apps have even a negative effect on reducing the prejudice perceived by VIPs and have no effect on reducing the prejudice of NIPs. For social connection and social acceptance, we find that these apps have a positive impact on both VIPs and NIPs. We hope this study can inspire more IS research on disability and we suggest several ideas for future research.
