    摘要： Techniques and functional electrical stimulation to eliminate discomfort during electrical stimulation of the retina are provided. According to a first technique, discomfort is eliminated through control of timing group assignment. According to a second technique, discomfort is eliminated through an edge detection method. According to a third technique, brightness clipping is used to eliminate discomfort. According to a fourth technique, direct reduction of current is obtained by scaling it down by a factor which is dependent on the sum of current in all electrodes. According to a fifth technique, the current being fed to each electrode is adjusted, by dividing it by a weighted sum of currents fed to the surrounding electrodes. According to a sixth technique, a method based on the current summation effect is used. According to a seventh technique, a large return electrode is used. According to an eighth technique, the return electrode is used for a pseudo-multi-polar stimulation.

    摘要： The present invention is an improved fitting and training system for a visual prosthesis. A patient, using the visual prosthesis observes a display and indicates location, movement, shape or other properties of the display image to provide for improved fitting and training. In one embodiment, the patient uses a touch screen monitory which displays an image. The patient touches the monitor at the location where the patient perceives the image. The system then corrects the image to the location indicated by the patient. In another embodiment a patient observes an image moving across the touch screen monitor and indicates by moving their hand across the monitor which direction the believe the image is moving. The system can then rotate the image to match the image perceived by the patient.
