No. I've been working as an electronic engineer for 19 years.
I'm feeling seriously burnt out, and I am not happy with being taxed to death, as well as a number of other things which I will not mention.
My post was inappropriate for the thread. I apologize.
I will refrain from posting to FR when in such a depleted, non-optimal state.
I really must sleep now. Good night.
Net porn just got a boost (as if it needed one).
HAHAHAHA...now here's a man who knows what he wants!
Yeah, but I'm still thinking about those prurient uses.
How much will it cost?
Should I buy telecom stocks?
Can I get this through AOL?
Does anyone have Britney's modem number?
(In control theory, it's called transport delay and it limits the achievable performance of feedback control systems.)
Not only do the users need frequent updates of the forces and positions (the article mentions 1000/second), but the system also needs to minimize the round trip time for a force to be propagated across the channel and for its resisting force to be propagated back.
I estimate that you can't do fine manual work with delays of any more than, say, a twentieth of a second. And even then, you'll have to learn to work through the system, mainly by slowing down somewhat.
The internet is not useful for this application because of the round trip delays. Not only are they too big, they're statistically uncertain.
Now, if you're going to do this job with brute force communication speed, you'll have to have a dedicated circuit, the most direct possible route (no satellite links!), and the lowest-overhead messaging protocol. So if you are using this approach and you want a surgeon in Sydney to operate on a patient in Topeka, I think you'd need a dedicated fiber optic line running directly through the center of the earth.
Another alternative, which I suspect they're working on, is to give each participant near-immediate locally generated feedback, based on a model of what's on the other end. The resulting force feedback would be modified by later-arriving data actually coming from the remote end. The model itself would be incrementally constructed in real time, being very rough at first and then getting better as the user continued to 'operate.'
But the construction of the model is quite problematic, especially when the object on the other end is connected to an essentally unmodelable nervous system.
IMHO, a problem nearly comparable to that of AI.

Would give cyber-sex a new meaning!
Does it matter?
I vote for Roberta Vasquez, who was in the first (and only) issue I ever owned (bought it off an older kid when I was 8, 1984).
I'm talking back in the day when we'd punch programs on cards, compile them and then put them through a card reader. If you were lucky and the gods smiled, after a few hours wait you'd get a printout of a nekkid woman done in ASCII. It would be a couple of pages you'd hang on a wall, then move back a few feet and squint to see it.
Those gals got lots of us geeks through lonely nights back in 1968-69!
Of course we were >supposed< to be making pictures of Snoopy or other cartoon characters, but we saw the possibilities right away.
And of course it spawned a race to see who could make the best picture! In the 70's I was printing them out with my Tandy COCO through a 3" wide 4 color inkpen printer. Color brought a whole new dimension to the ...uhhh..art.
Wish I could find some of those old programs now...sigh. Maybe I'll try to ressurect the COCO and dig through the files.

What is Roberta up to nowadays? I would like to see some recent pics of her. BTW, Petra Verkaik was the Playmate in the last issue of the decade of the 80s---December, 1989. After that began the downfall of Playboy with its obsession with implants and Playmates who looked like they all had identical factory stamped artificial looking bodies.
