Today, the application scenarios of the Internet and information technology in the construction of barrier-free environments are constantly expanding. Aging-friendly smart devices bring high-quality life experiences to many elderly people. Barrier-free urban governance systems use intelligent hardware and software to provide more convenient and inclusive services for people in need. Visually and hearing-impaired users watching movies and listening to music on mobile phones have also become a reality from imagination. Technology is changing people’s lifestyles, promoting the transformation of social disability-assistance work from hardware to intelligence and digitization. While helping people with disabilities access information, it also draws them back into social life, striving to practice the social development goal of “no one left behind.”
