Figure 6.

Illustration of the utility of the image enhancement app on the Glass by a patient with AMD. (A) A retinal image of a patient (presented upside down to correspond to the visual field orientation of the other figures) with superimposed perimetry polar grid centered at the PRL. The location of the PRL, as measured by the Nidek MPI, and the calculated bivariate ellipse including it are shown with a frame, the size of the field of the Glass, centered on it (Virtual Display). A (doted orange) circle of 36° diameter centered at the PRL, illustrates the retinal span of a 12° field-of-view of a 3.0× bioptic telescope, which provides a distal field-of-view similar to that of the Glass display. (B) A room scene taken with the Glass, illustrating a series of possible objects to be examined by the patient using the image enhanced Glass. (C–F) Sequential scene scanning with edge enhancement at the selected gazed locations. The space variant imaging (eccentric-wise blurring) and HDR conversions are applied to a scene image to illustrate perceptual view of the patient. Note that unlike the bioptic telescope, all surrounding parts of the scene remain visible throughout the scanning process. In these images the illustrated blur is applied over the enhancement to illustrate the improved visibility provided by the enhanced edges.
