You have to depress the fingernail edge slightly (where the flesh almost starts). A little like a mouse click. But the finger is not touching from close observation.

I will reiterate your nails are doing nothing,no matter their shape.
lol, I am aware it is not the finger nail per se. Its just being used as a regular and consistent reference point (if you always use the same point) to transmit the capacitance from your finger as you press the nail in. That's probably what gives it its accuracy.

Anyway, I wouldn't be so stupid to suggest something that is easily non-reproducible and easily debunked with common objects. And I am sure what I am doing can be easily explained, but all I know is that it works using the stipulations set.

Again... your nail is not a conductor, so it can't "transmit" "capacitance"...

I will leave the suggestion as an experiment if anybody wants to try it. Or to explain it.

I have long fingernails. In my experience, using nail only results in no response whatsoever from a capacative screen. When using a friend's iphone (I know, I need to change my friends) I am forced to completely change my screen technique to get any reaction out of it. And yes, I have nails long enough to test nail only with no finger contact.

Don't you mean claws, on your paws, not nails?

That'd be right. Claws on my paws like crocodile jaws...

Either way, the point stands.

I can put my finger behind a cotton shirt and manipulate the iphone. I am beginning to think my point stands. Either that or I am superhuman, which wouldn't surprise me either.

This thing still has legs?

Cotton shirt isn't enough to block the effect. Other, thicker materials can be.

EDIT: oh, and I can hover a little over a trackpad and get inadvertant mouse moves/clicks. Way too often for my liking. But the capacitive field only extends so far. I'm betting RevdKathy never suffers this...

Resistive vs. Capacitive fight has just surpassed Amiga vs. Atari ST* as the most boring effing geek-war ever.









*Yes, I'm both old and nerd enough to have taken part in it.
