Figure 7.

View of the escalator from where the subjects were seated (left), with no filter (center), and distance filter settings (right). The center and right images are the input images for the Argus II system. The blue rectangle in the left image shows the Argus II field of view within the much wider camera field of view, while the center and right images show the magnified view of image inside the blue rectangle, which was presented to the Argus II user in the no filter condition (center) and the distance filtered condition (right). Note that under the no filter condition both persons appear dark against the brighter background, whereas in the distance filtered image only the closer person is seen as a bright silhouette after filtering out the background information (See Supplementary Movies S3 and S4).
