When you apply pressure to a capacitive screen, it will only recognize the action if it has an electrical current. The naked hand delivers these electrical impulses directly to touchscreens. This is why the wool mittens your Aunt Vi made won't work on most touchscreen devices.
What makes a tech gadget a "gotta have it" item? The answer is simple: It has to offer something useful not featured by any of its competitors.

Touching a screen and moving objects is pretty intuitive. But there will always be people who long for reality. Real buttons to push, real levers to flip, tactile controls that provide immediate feedback.
Suddenly, the boundary between the virtual and the real is all around us, a vanishingly thin plane that can be stretched over any real-world object, and that can connect us, with fingertip pressure, to the deep digital, social, data-rich world behind that object.

For now, Displair remains something of a curiosity, albeit an incredible one. One unit costs about $10,000 (plus one to two
Amazingly, Touche sensors can also be applied to liquids. As seen in the demonstration video above, a single electrode attached
It's a bit of a clichè, but the closest analogy for what this technology enables is really from a scene in "Minority Report
