In this paper we present Farfalla, a web tool designed to support people with various limitations, ranging between mobility problems and visual impairments. The main goal of Farfalla is to integrate typical Assistive Technology functionalities into a web-based platform in order to enable users with disabilities to browse web pages and to fill forms using different input and output methods. The project is still in progress: the user interface and one of the possible input methods have already been prototyped, while some other functionalities have still to be developed.
