Abstract:
1. A method of electrically stimulating a patient's retina with an electrode array implanted in the patient's eye, the method comprising: capturing one or more images of a visual scene, including one or more objects located in the visual scene; detecting at least first and second lines and/or edges of the one or more objects in one of the one or more images; identifying a first line of electrodes in the electrode array corresponding to the detected first line and/or edge and identifying a second line of electrodes in the electrode array corresponding to the detected second line and/or edge, wherein the second line of electrodes is different from the first line of electrodes, the first and second lines of electrodes each comprising at least 3 electrodes; applying electrical current simultaneously to the at least 3 electrodes of the first line of electrodes to provide a visual percept to the patient of the entire detected first line and/or edge; and after applying electrical current simultaneously to the at least 3 electrodes of the identified first line of electrodes, applying electrical current simultaneously to the at least 3 electrodes of the second line of electrodes to provide a visual percept to the patient of the entire detected second line and/or edge.
