Until now, I had no contact with deaf-blind people.
One day, I realized that it would be convenient to set the “vibration” of my smartphone to Morse code only for certain people when one can’t use his/her eyes or ears, such as when driving.
For information on how to operate a smartphone in this way, please watch this video.
(…..Oh, sorry ,all in Japanese! )
If you hit simple words slowly in Morse codes, you can clearly distinguish different codes even if the phone is in your breast pocket or pants pocket. Even people who don’t understand Morse code should be able to sense ”the rhythm” well enough.
I also tried it with my toes. They don’t seem to be as sensitive as my fingers, but even if I type a little faster, I can read it as easily as my fingers……Oh, so Morse code can be received anywhere on the body.
It was in the fall of 2022 that I realized this, which is obvious when we think about it. “Morse telegraphy is simple, but somehow profound…” Telegraphy is the world’s first form of electrical communication, so at the time, it was not the time to talk about hardware or software or such casual things, but rather, “It’s fine if it’s simple, but let’s just communicate!”
It’s been 50 years since I bought a telegraph key, even before I started ham radio. I didn’t know why I liked it, but I think it was probably something like that… that is, I was attracted to the DNA of the telegraph, which has become a universal design as a result of its origins.
