The ultimate goal of AI technology is to make human life more convenient. For people with disabilities, AI technology is not only a matter of convenience but also a crucial element in enabling social integration. This paper studies various cases where AI technology enhances the quality of life for individuals with disabilities. It analyzes the potential of AGI, the effectiveness of currently available AI services and applications, and discusses the innovative applications of AI in smart home systems and the utility of affordable AI tools. The study involves 2,200 individuals with disabilities, and the improvement in quality of life due to AI is evaluated through two-way ANOVA, considering age and income level. The analysis reveals that both age and income level significantly impact the improvement in quality of life due to AI.
