Reducing Inattentional Blindness Using Subliminal Cueing in Visual Performance Tasks

Abstract

Not all the visual information acquired by the eyes is processed by the human visual system. Human visual attention selects information most relevant to the task being attended. Unexpected objects get overlooked when we are busy attending something else. Inattentional blindness is a psychological phenomenon where a visual stimulus goes unnoticed by the observer. This paper presents a research study on using subliminal cues to cause subliminal attention shift in a video scene showcasing inattentional blindness. The goal of this work is to develop and optimize video processing systems for applications such as surveillance and driving safety. Preliminary results indicated that subliminal visual cueing helped in making aware of other objects or events happening in a scene other than the prime task.
