Visual prosthesis for phosphene shape control
The present invention is an improved method of stimulating visual neurons to create artificial vision. It has been found that varying current of visual stimulation can create varying percept brightness, varying percept size, and varying percept shape. By determining the attributes of predetermined current levels, and using those attributes to program a video processor, more accurate video preproduction can be obtained.The present invention also includes an electrode array having alternating large and small electrodes in rows at a 45 degree angle to horizontal in the visual field.
