Some day soon, you'll be able to order a wedding dress on your tablet and feel the fabric and the veil just by touching the screen. When you feel an object, your brain registers the series of vibrations on your skin as being smooth, rough, sharp, etc. Computer sensors are becoming sophisticated enough to do that too.Within the next five years, vibrators within smartphones will be precise enough that they could be designed to mimic the vibrations experienced when your fingers touch a particular surface. Even though you'll just be touching glass, it will feel like you're touching whatever object is displayed on the screen. Source: The Coming Crisis
