The present invention relates to a technology of, in place of transmission or reception of a bioelectrical signal to or from a living body, manufacturing a machinery device having almost the same structure as that of a living body and capable of performing transmission or reception with almost the same frequency as that for the bioelectrical signal, wherein a signal wave received from the machinery device is output, so that an auditory signal, a visual signal, and another bio-signal are output through corresponding output means, such as a display and a speaker. The machinery device comprises one or more among a brain, an ear, an eye, an arm, a leg, a hand, a foot, and a wing which are the major organs of a human body or another animal, and comprises a storage means for storing a transmitted or received bioelectrical signal, and the output means include one or more among a display and a speaker. In the output means, among multiple visual-related cortexes, a visual signal of the bioelectrical signal occupies the largest area at a primary visual cortex of the brain of the machinery device having almost the same structure as that of a living body and capable of performing transmission or reception with almost the same frequency as that for the bioelectrical signal. However, the portion of a retina and a region in which an input has occurred have been accurately determined, and this is referred to as retinal region restoration or a view-corresponding visual map. The present invention further comprises outputting a visual signal of a bioelectrical signal after forming a display corresponding to a visual map so that pixels of the display are viewed like an actual scene in front of eyes, wherein: instead of producing a machinery device having almost the same structure as that of a living body and capable of performing transmission or reception with almost the same frequency as that for the bioelectrical signal, transmission or reception is allowed to be performed in a compu
