We evaluate and test the accessibility of web services. Accessibility in web services means that everybody can use the service – including people with disabilities or limitations, such as visual impairment, hearing loss, learning difficulties and different aging-related limitations. Accessibility evaluation is based on the WCAG 2.1 guidelines and is conducted with the help of screen readers where applicable. In addition to an accessibility evaluation, we can test services with actual users. It is often beneficial to complement an accessibility evaluation with a few users from special user groups.
