Improving User Experience of Eye Tracking-Based Interaction

Today’s systems for gaze-ased computer access through mouse and keyboard emulation incur unnecessary interaction and visual overhead for users, aggravating their user experience. We discuss how knowledge about interface semantics may help to reduce interaction and visual overhead, enhancing user experience. We propose an introspection of Web interfaces that determines the semantics of interaction elements on dynamic Web pages during browsing and adapts them for improved gaze control. We have developed Gaze The Web, a Web browser that includes these capabilities to enhance the gaze interaction experience. In a summative lab study with 20 participants, Gaze The Web allowed the participants to accomplish information search and browsing tasks significantly faster than an emulation approach. Additional feasibility tests of GazeThe Web in lab and home environment showcase its effectiveness in accomplishing daily Web browsing activities and adapting large variety of modern Web pages to suffice the interaction for peoplewith motor impairment.
