The purpose of this study was to clarify the conditions under which the drive phenomenon, in which short, discontinuous strikes are connected and become illegible, is suppressed in blind and normal subjects with closed eyes, and the success rate of recognition between blind and normal subjects with closed eyes as a function of the energization condition in signaling interpersonal proximity information. The participants were blind and able-bodied people. They were members of the Association of the Physically Handicapped and the Blind in Kusatsu-machi, Gunma Prefecture, as well as members of a university laboratory. The experimental period was from September 2021 to March 2022. The experiment was conducted from September 2021 to March 2022. The sites were Gunma Paz University and the Welfare Center in Kusatsu-machi, Gunma Prefecture. Success is the response occurred after a time lapse of less than 5seconds; it was considered a hazard avoidance success. Eye masks were not used in the blind subjects, while masks were worn over the eyes in the healthy subjects. The experiments were conducted in random order according to experimental design L (2) 8, and twelve trials were conducted with the addition of the no approached condition. Results showed that the hazard avoidance success rate was 31.9% for blind subjects.. All of them occurred with the combination of electrodes without hygroscopic material, which produces the so-called drive phenomenon, and with stress load, in which the participants were instructed to quickly judge the interpersonal distance. Conclusion, the results suggest that the use of hygroscopic electrodes may be more effective in improving signal resolution.

To clarify the mechanism of the drive phenomenon in blind people, in which short, discontinuous strikes are connected and become illegible, by quantifying the amount of psychogenic sweating during electric current application to signal interpersonal proximity information to the blind person by quantifying the bioimpedance. Participants were blind people from the Association of the Physically Handicapped and the Blind in Kusatsu Town, Japan. The participants were used by the low-frequency electric current interpersonal distance recognition system, and were considered to have successfully avoided danger (success) if they were able to recognize a human body within 5 seconds of its appearance at a distance of 2 m or 1 m, or if they were able to recognize the absence of a person within 5 seconds. elapsed before the person reacted, it was considered a hazard avoidance failure (hereafter referred to as failure). Outcome: The bio-impedance was measured before and after the experiment together with the success rate. The experiment was conducted in a random order according to experimental design. The results showed that the so-called drive phenomenon occurs when electrodes without hygroscopic material are used and instructions are added to quickly determine interpersonal distance, the only bioimpedance that showed a 250 For the KHz input, there was a significant difference in median variability between risk avoidance success and failure. The mean value was -2.4 Ω for success and -0.4 Ω for failure. Conclusion, the variation in bioimpedance, which indicates the amount of psychogenic sweating during energization in the signalization of interpersonal approach information to a blind person, tended to be larger when the signal resolution was higher.
