  • Now, \'feel\' images on your smartphone
  • Date: 2013-10-11
  • Smartphone users can now 'feel' images and objects seen on their touchscreen! In a game-changing invention, engineers at Disney Research, Pittsburgh, have developed a new technique that allows you to feel the texture of objects seen on a flat touchscreen.

     

    The novel algorithm enables a person sliding a finger across a topographic map displayed on a touchscreen to feel the bumps and curves of hills and valleys, despite the screen's smooth surface.

     

    The technique is based on the fact that when a person slides a finger over a real physical bump, he perceives the bump largely because lateral friction forces stretch and compress skin on the sliding finger.
