You didn't only use the back of your arm, did you?

    I have a small number of fine hairs on the back of my fingers' first section. That's the sharpest and most sensitive body part that fulfils the criteria and I think I could "scan" the screen with it. I also remember feeling something with the tips of my fingers, maybe ionic wind or capacitive current flow at 60 Hz (refresh rate).

    Wild that most households just used to have a 25kV particle (electron) accelerator but maybe an array of 3x800x600 transistors (TFTs) wired by transparent coating on glass is wilder.
