A system for providing hands-free input to a computer. The system includes one or more artificial cilia mounts attached to an eyelid or eyelash of a user, by which one or more of the artificial cilia extending therefrom are adapted to cause generation of an input command in response to an intentional blinking motion, and a computer to which blinking-derived input commands are transmittable. The system further includes a movement sensor mounted for detecting a calibrated instantaneous head orientation of the user. The system includes a means for duplicating a portion of video data or a representation thereof that would cause corresponding images to be viewable by the user on a computer screen in response to the instantaneous head orientation and for displaying the images corresponding to the duplicated portion.
