Abstract
Visual prosthesis apparatus includes an image receiver, a processor coupled to the image receiver, a stimulation device coupled to the processor, and an eye monitoring device coupled to the processor. The image receiver receives a sequence of images and the processor produces a stimulation signal at least partially in accordance with the received images. The stimulation device receives the stimulation signal and stimulates visual neurons of a user accordingly to provide the user with a visual percept. The eye monitoring device monitors one or more ocular parameters at an eye region of the user, wherein one or more control functions are associated with the monitored ocular parameters. The processor controls the visual prosthesis apparatus in accordance with the monitored ocular parameters and the associated control functions. The one or more ocular parameters can include pupil size, state of closure of the user's eyelid and direction of eye gaze.
