Abstract Traditional web interfaces often rely on keyboard/mouse input to work. This characteristic forces people with reduced mobility to adapt or do not use the applications at all. This paper proposes a prototype to increase web accessibility for people with reduced mobility. Our prototype proposes an eye gaze based interaction between the user and web browsers displaying a web site (compliant with the web content accessibility guidelines proposed by the World Wide Web Consortium). We implemented a plug-in that adds functionality to allow user navigation, cursor control and text input. Keywords Digital inclusion tracking

1 Introduction Traditional web interfaces rely on keyboard/mouse input to function. This characteristic forces people with reduced mobility to adapt or do not use the applications at all. The main goal of inclusive interfaces for people with reduced mobility is to consider the human factors of users in the interface design. For instance, an inclusive interface design should allow access to web content to a person with reduced mobility in a natural way.

Eye gaze interaction provides a tool to increase web accessibility via graphical user interfaces (GUI) for users with reduced mobility. With an eye tracking device, it is possible to detect the user eye position in an unobtrusive way, thus, a person with reduced mobility can access web content and applications developed for traditional GUIs. To improve accessibility for users with reduced mobility, it is not necessary to re-engineer the interfaces models. They can be adapted to eye gaze navigation. Diverse mechanisms such as eye fixation combined with high fidelity icons and eye gaze triggered gestures can be used. In this project, we designed and implemented a wrapper for web content with controls and tools that enables fluid user interaction for people with reduced mobility. We developed a web browser plug-in that allows eye gaze interaction for web content. Our solution models available events in web browsers and provides accessible ways to trigger such events. Navigation is improved using controls located within the natural scrolling space so the user can scroll freely throughout the web content. Further, the user can use a set of tools in order to improve web content interaction. Our solution allows users with reduced mobility to access and interact with web content otherwise inaccessible. Therefore, we achieve accessibility and inclusion for our target audience. A related work review
