【 摘 要 】

In this experiment, we test the hypothesis that a 'retina-like' space variant sampling pattern can improve the efficiency of a visual prosthesis. Subjects wearing a visuo-auditory substitutionsystem 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 accuracy wasenhanced, as was the speed to find the target. Surprisingly, the time spanned to complete the trainingwas also reduced, suggesting that this space-variant sampling scheme facilitates the mastering ofsensorimotor contingencies.
