Hey all,
I'm new to ez so just wanted to say hello before continuing. It's great to be aboard! Seen a lot of interesting things so far. In kind, hopefully this is something that will pique your interest.
This is a (relatively) new technology patented by Disney dubbed "
Swept Frequency Capacitive Sensing". It could essentially turn any surface in any building as well as any handheld items (Think iPhone/Android/Tablet...) into incredibly accurate, touch-sensitive controllers without any kind of touch-screen hardware required by today's devices.
With this technology it's conceivable that you could one day (very soon) input information into your pc by tapping on the table following an imaginary keyboard or some other pattern, like you might see in certain sci-fi anime or other such fiction... Absolutely fascinating. And concerning at the same time. Imagine what intelligence agencies could accomplish with capabilities like this...
