Impact of Intermediary Feedback on Eye-tracking

People who are unable to use speech to meet their communication needs often use augmentative and alternative communication technology systems. Though many access their systems by directly touching a screen or keyboard, others with significant physical disabilities use alternate access methods. An increasingly common access method is the use of eye-tracking technologies (Fager et al., 2012), where cameras on the front of a device record where a user is looking in order to move and make selections with the on-screen mouse. This method requires users to look at the screen to move the cursor, and then to sustain their gaze on their selection for a pre-determined amount of times (i.e., dwell). The purpose of the study is to understand the impact of different types of visual feedback used to illustrate whereto cursor is on a screen on people's ability to navigate the screen with their eyes.
