Summary: Touchscreens are cool and all but everything you touch feels like glass. Until now. Disney researchers have discovered a way to trick the brain into "feeling" different textures. It involves sending tiny vibrations through the display to create a sensation of feeling ridges and shallow bumps. As a bonus, they believe that this algorithm should be simple to add to existing touchscreens.
Our skin detects textures from the stretching of our skin so the vibrations form the surface artificially stretch the skin to simulate the texture. The bigger the feature, the bigger the vibrations.
I can't wait to see this being used in museums and zoos all over the world.
