Acoustic Sensors Make Any Surface a Touch Pad 142
An anonymous reader writes "Using cheap acoustic sensors the surface of any 3D object can be instantly made into a touch-sensitive interface capable of tracking two objects at once. Its creators are planning to make hospitals more hygienic — keyboards and mice will be replaced by desks wired to perform as keyboards and touchpads. A video shows it in action [.wmv]."

While I don't know if this statement is true or not, however the question you should be asking is how many people died at home that would not have died if they were in a hospital.
I eschew drugs unless as an absolute last resort, unlike so many Westerners these days who seem quite happy to self medicate with OTC concoctions at the least symptom and turn to the doctor for prescription medication to cure everything from a head-ache, insomnia, fatigue, and malaise to spoiled children, when usually all that is needed is a good diet, exercise, fresh air and hard work, and in the case of spoiled children, a firm hand.
On this I agree with you. :-)

Will this thing work with the 3D surface of my cluttered desk? I doubt it will track the position of my fingertips on a piece of paper after I've picked it up from the desk, without sensors attached to the paper.
When these sonar sensors can actually track objects inside a 3D volume, not just across a surface in 3D space, they'll have made a major leap in UI. Until then, I don't see how these sensors are different from the touchscreen bezels mounted on monitors for years, except they've figured out how to discard the frame, and supposedly do without calibration.

Some 20 years ago, when electronic daisywheel typewriters were starting to take over, Smith-Corona/Marchant came out with a novel way to keep using their mechanical typewriter tooling. They used a conventional mechanical keyboard, where the keys stuck a bar of steel with a piezoelectric sensor at either end.
The delay between the time the impulse reached each sensor enabled a microprocessor to pinpoint exactly where the bar was impacted, and thus deduce which key was pressed.
That's basically the same principle applied, but in three dimensions.
