Claim:
1. A method, comprising: providing a visual prosthesis a portion of which is adapted to be implanted in a subject, the visual prosthesis comprising a video processor and an array of electrodes; selecting and defining a first set of geometric shapes; selecting and defining a second set of geometric shapes; displaying a geometric shape from the first set of geometric shapes to the subject, wherein the displaying is by stimulating a plurality of electrodes in a multi-electrode pattern within the array of electrodes corresponding to the geometric shape; recording a drawing by the subject on an electronic input device of the geometric shape perceived by the subject, thus creating a described shape; comparing the described shape to geometric shapes from the second set of geometric shapes and determining a selected shape in the second set of geometric shapes closest to the described shape using an automatic tool; and adjusting the visual prosthesis based on the comparing of the described shape and the selected shape, thus performing spatial fitting for the visual prosthesis; wherein the steps of selecting, comparing, recording and adjusting are by autonomous processes in the video processor.
