Apologies if this has already been covered.



Remember that recent patent that had fingers and hands all over the screen of a (possible) tablet?



You will not believe this.



Click on the Multi-Touch Interaction Experiments.





Wow! Just... wow!

Even if it's fake, it's a neat dream!

    Holy Crap. Were do I get one?



    Better yet... where do I buy stock?

    I was making fun of this about a week ago; said it was fantasy.



    Damn.



    Damn!

    1. I'm buying stock in that technology.

    2. I'm buying stock in Windex.

    In a Video iPod? In about a month? For me, this would well and truly be the actual end of the 20th Century.

    How does this work? Does the surface bend slightly? Since it's reflecting off the inside of the acrylic, how does a finger on top of it affect the light?

    Total internal reflection requires a high refractive index difference between two media (like air and water, glass and air). At the surface-air interface, due to the fact that the electric field of the light cannot be discontinuous (it must extend beyond the surface a ways), this is the so called evanescence wave, when you place your finger on the surface you absorb some of the energy of the light which is being reflected changing the intensity and direction of the reflected wave (scattering)...

    P.S. I asked this in the other thread about this, but that thread died. Does anyone know of a way to get OS X to display two cursors, or as many cursors as there are pointing devices? I'm thinking about the situation with a very large screen or multiple monitors where you might want a graphics pen to be devoted to the drawing area and the mouse to be devoted to interacting with the menus and controls.

    Nice. This is the next step in the evolution of the Mac. Well, it could be Isn't this the kind of stuff Media Lab @ MIT should be doing? I was reading on some tangible media work a few years back. Not sure what they're up to now.

    I am perplexed, thoroughly. I really want to know

    how GUI will look like in 10 or 20 years.
