ABSTRACT:
An optic nerve image output device and method for modulating image signals output by an image output device with low-frequency square waves output by a square wave output device and outputting this modulated output at the portion acted upon by optic nerve at the head on the human body side with an output device. If low-frequency square wave signals are applied to the portion acted upon by optic nerve at the head on the human body, the optic nerve can visually feel a square screen by light and scanning lines on that screen. For that reason, if video signals are applied after modification with such low-frequency square wave signals, an image is directly felt by the optic nerve, making it possible for not only healthy persons but also blind persons to recognize the image and thus also making it possible to use the human body as a display.
