Abstract

There are currently three main kinds of eye tracking applications: gaze-responsive, gaze-aware, and gaze-contingent. A fourth classification, termed gaze-guiding, to our knowledge, coined and implemented for the first time. The gaze-guiding technique is the use of motion, light, color, or other visual stimuli to modify the user's fixation to predetermined locations when the user fixates on specific areas of interest. To test the technique, an education software program that teaches physics through the use of gaze-guidance was developed. It is suggested that a natural mapping exists between gaze-guidance and the software's built-in lesson plan. It is also speculated that gaze-guidance reduces the extraneous cognitive load of associating written and visual problem elements. An experiment was conducted to evaluate gaze-guidance. Although not found to significantly affect performance, most participants considered gaze-guidance helpful, especially for difficult problem examples.
