Simulation of the appearance of spatial vision multiplexing. (a) A street-crossing scene as it might appear to a patient with tunnel vision using the augmented vision system that provides an expanded VF. The woman’s head is seen in full resolution through the display as well as in the superimposed minified contour image. The contour (edge-image) provides a wide field of view enabling detection of the pedestrian (on the left) crossing in the other direction (a potential collision that would not be visible without the display). (b) Illustration of the effect of enhancement by superimposing 1:1 scaled edge images of the scene over the natural view, an application that may be beneficial for patients with central vision loss.
