Visual confusion is the core mechanism for field expansion in patients with field loss to detect collision in mobility. Although binocular visual confusion using unilateral device (one eye only) is common, binocular rivalry reduces the detection performance in mobility. We develop new monocular visual confusion devices (optical see-through device) and reveals the visual mechanism of monocular visual confusion with considering contrast reduction, providing stereoscopic depth cues, and coherency of motion flows. This mechanism could explain the visual perception in augmented reality (AR) and see-through displays.
