Interface-free computer screen

Question

** not directly related to Java **
This is interesting. Imagine all the new applications. See the presentation after the short BMW ad:

Jeff Han is a research scientist for New York University's Courant Institute of Mathematical Sciences. Here, he demonstrates�for the first time publicly�his intuitive, "interface-free," touch-driven computer screen, which can be manipulated intuitively with the fingertips, and responds to varying levels of pressure.

Answer 1

** not directly related to Java **not at all related really.
but yea WOW! so let me get this right:
instead of using a stylus or wireless mouse with which in a 3 inch
range of motion I get total screen coverage I might now have the ability
to use my dirty greasy fingertips to smear up my entire display system
while having to flail my arms around to traverse the entire 2-3 feet screen display (in the demo).
Or better yet ill be forced to make the horrible compromise -
do I lay it horizontal so i can type on it or vertical so i can see it?
Its essentially a gigantic mouse pad where you use your fingers.
Itll be great to program for. Ill have to calibrate my programs so that
people with varying strengths can use it without their different
touch pressures making the program unusable.
All kidding aside though, itll be great when we are all living with those
Minority Report computers. Instead of carpal tunnel ill have the pleasure
of throwing my arms around in the air to hit invisible keys.
By the way im just playing Devils Advocate. It it pretty cool. I actual bought a small 3 inch touch screen display to program and mess around with at home a few months ago. : )
