Conversely, one crucial aspect remains out of bounds to individual agency: The User Interface. Today, designers perform studies in order to understand the interface that satisfies the majority of the users. Unfortunately, it is impossible to create a solution that satisfies the whole community, as users have different necessities and preferences. This thesis aims to solve this issue, allowing users of web interfaces to tweak and share adaptations with other users, shifting the agency of UI adaptation from developers to users. To achieve this, a prototype that allows users to create and save changes to web interfaces was developed. This prototype connects to a platform that allows other users of the community to search and share customized web interfaces. Using this platform, users can replace any UI with an adapted version that satisfies their necessities. Our platform aims to benefit not only the community, giving the users access to a collection of UI adaptations where they could browse for the ones that match their necessities, but also the website owners, informing them of what could be improved. This platform benefits the community since it provides the users with a variety of UI adaptations that should match all their necessities; but it also benefits website owners, reducing their burden to provide accessible web content, since the community can create their accessible version of any web page.engInterfaces de utilizadorAcessibilidadeContribuição colaborativaAdaptaçãoAplicação WebTeses de mestrado - 2023master thesis203491440
