For something to be considered accessible, it has to be available and open to all users, especially people living with disabilities. Accessible software is designed to enable the use of a product by a person with a disability or impairment. In many ways, the standards that define open source software overlap with the process of Accessibility in software development. However, today, several products and tools are designed with accessibility barriers, which creates a problem for developers and users. Open source communities should embed accessibility in its fundamentals for setting up open-source software. In this session, I will be speaking on; What Accessibility is all about? How open-source processes relate to adaptive accessibility software. Why Accessibility is important in open source. How the OSS community can improve Accessibility in software development. Open-source web accessibility tools.
