People with severely restricted peripheral visual fields have difficulty walking confidently and safely in the physical environment. Augmented vision devices that we are developing for low-vision rehabilitation implement vision multiplexing, providing two views of the same scene at two different scales (sizes), with a cartooned minified wide view overlaying a natural see-through view. Inattentional blindness may partially limit the utility of these devices as low-vision aids. Inattentional blindness, the apparent inability to notice significant but unexpected events in an unattended scene when attention is fixed on another scene, has classically been demonstrated by overlaying two unrelated game scenes, with unexpected events occurring in one scene while attention is maintained on the other scene by a distractor task. We hypothesized that context like that provided by the related wide view in our devices might mitigate inattentional blindness in a study with two simultaneous views of the same scene shown at different scales. It did not, and unexpected event detection rates were remarkably consistent with our and other mixed-scene studies. Still, detecting about half of the unexpected events bodes well for our use of vision aids that employ vision multiplexing. Without the aids, is it likely that many more events would be missed.
