Abstract (Summary)

As eye-tracking become ubiquitous, the chance of systems using eye-gaze control interfaces increases. However, there is a lack of research explaining eye-gaze control’s effect on user perception. Eye-gaze control may alter how users visually perceive their environment. Eye-gaze control may require movements that disrupt normal visual attending. Eye-gaze control may also alter visual attention by decreasing the likelihood of visual detection. This means eye-gaze control used in complex settings (i.e. driving, aviation, etc.) could increase potential harm to users and others. Therefore, it is important to identify potential changes to a user’s perception. The current study was composed of two experiments examining costs to visual attention. A total of 48 CSULB students participated (24 each experiment). Participants tracked a cursor on a screen or controlled the cursor with mouse or eye-gaze control. Concurrently they responded to stimuli appearing in either peripheral or central visual areas. Responses and reaction times (RT) were gathered. The results suggest eye-gaze control disrupts visual attention and increases attentional load and inattentional blindness. Eye-gaze control had the most missed stimuli and slowest reaction times for peripheral and central targets. This study suggests effects of eye-gaze control on visual perception should be considered in system design and eye-gaze control should be limited to non-critical tasks where users won’t be harmed if they miss an event.
