Hey, Mal. We do like to have our fun sometimes, don't we?
In reality, regarding the OmniTouch device, it may not be as new as it first appears. Your post made me think of disabled people (quadriplegics in particular, like famous scientist Stephen Hawking), who are confined to wheelchairs, but are hooked up to electronic devices that let them manipulate a computer.
Some do it by voice command; some by eye movement; I think some have a little tube device near their mouth that they can puff air into to activate certain things.
As technology improves and miniaturizes, these devices will get more portable and more widely used.
And then, of course, there is the burgeoning field of nanotechnology
. Even now, scientists are building programmable structures on a microscopic scale.
I can see the future coming and it is here, now!
