Abstract: In this experiment, we test the hypothesis of whether a 'retina-like' space variant sampling
pattern can improve the efficiency of a visual prosthesis. Subjects wearing a visuo-auditory
substitution system were tested for their ability to point at visual targets. The test group (space-variant
sampling), performed significantly better than the control group (uniform sampling). The pointing
