A Gaze-Based Web Browser with Multiple Methods for Link Selection

This paper presents a gaze-based web browser that allows hands-free navigation through five different link selection methods (namely, Menu, Discrete Cursor, Progressive Zoom, Quick Zoom, and Free Pointing) and two page scrolling techniques. For link selection, the purpose of this multi-approach solution is two-fold. On the one hand, we want users to be able to choose either their preferred methods or those that, in each specific case, are the most suitable (e.g., depending on the kind of link to activate). On the other hand, we wanted to assess the performance and appreciation level of the different approaches through formal tests, to identify their strengths and weaknesses. The browser, which is conceived as an assistive technology tool, also includes a built-in on-screen keyboard and the possibility to save and retrieve bookmarks.
