Transmitting and receiving a bioelectrical signal from a living body Create a mechanical device with almost the same structure that can transmit and receive at almost the same frequency as the bioelectrical signal, and output a signal wave received from this mechanical device to display auditory signals, visual signals, and other biological signals as display means, each output means. As output through The mechanical device includes any one or more of the brain, ears, eyes, arms, legs, hands, feet, and wings, which are the main organs of the human body or other animals, and the output means include any one or more of the display and speakers. It includes storage means for storing bioelectrical signals. The visual signal of the bioelectrical signal in the output means occupies the largest area among the multiple visual relational orders in the primary visual age of the brain of a mechanical device having an almost identical structure capable of transmitting and receiving at substantially the same frequency as the bioelectrical signal, but some part of the retina It is determined exactly where the input is from. This is called a retinal region restoration or visual map corresponding to a field of view. In response to the visual map, the display is formed so that the pixels of the display look like the scene in front of the eyes, so that the visual signal of the bioelectrical signal is output. Includes Instead of making machinery with almost the same structure that can transmit and receive at almost the same frequency as the bioelectrical signal It is possible to transmit and receive data from a computer in the same way as a mechanical device of almost the same structure capable of transmitting and receiving at almost the same frequency as the bioelectrical signal. The audio and visual signals and other bio signals are processed by processing the signals transmitted and received from the computer so that they are output in the same way as those output from signal waves
