KeySurf: A Character Controlled Browser for People with Physical Disabilities
(0) For many users with a physical or motor disability, using a computer mouse or other pointing device to navigate the web is cumbersome or impossible due to problems with pointing accuracy. At the same time, web accessibility using a key-board in major browsers is rudimentary, requiring many key presses to select links or other elements. We introduce Key-Surf, a character controlled web navigation system which addresses this situation by presenting an interface which al-lows a user to activate any web page element with only two or three keystrokes. Through an implementation of a user-centric incremental search algorithm, elements are matched according to user expectation as characters are entered into the interface. We show how our interface can be integrated with a speech recognition input, as well as with specialized on-screen keyboards for people with disabilities. Using the user’s browsing history, we improve the eciency of the se-lection process and find potentially interesting page links for the user within the current web page. We present the results from a pilot study evaluating the performance of var-ious components of our system.
