But Science, maintaining careful eye contact, courteously flips that statement the bird. Because not only do they have the technology all figured out, but it's totally going to hit the market within a few years.
You could be TouchSkyping your grandpa by 2015.
In fact, there are two different ways of achieving the seemingly impossible. A company called Immersion is developing a more sophisticated version of the vibration function. Using a set of advanced, localized vibrations, the technology is able to manipulate your sense of touch to make you think that the smooth touchscreen has ridges and bumps. Add a correct set of vibrations to a picture of, say, a tiled wall, and you'll be able to feel all the bumps and cuts of the surface as if it were real.
Which is great news for everyone with a kitchen tile fetish.
