h a l f b a k e r yIncidentally, why isn't "spacecraft" another word for "interior design"?

Pretty much covered in the title. The "display" could be used in phones or any other interfaces for the blind. The amount of charge could be altered to relate the amount of "darkness" of that point.

How do you convert the charge on the capacitors into
something people can feel? |

You say that like it's a bad thing. |

You'd definitely need something analogous to a brightness control to vary voltages based on skin types. My guess is you'd end up using high voltages (~100V) with no amps. This should give a slight tingle but not anywhere near painful. |

I guess unless you want it to be.... |

This may work, but I doubt it. For one thing, the electrical
conductance of the skin depends hugely on dampness and on
pressure. For another, braille users rely on the light-touch
sensors in the fingertips, which are very densely packed.
This system might stimulate these receptors, but I think it's
more likely to trigger other receptors which are not so
densely packed (eg, heat, pain). |
