Senseg.com is a haptic interface company based in Helsinki which is developing a new “type” of touch screen that let’s you feel different surfaces.
Instead of using vibrating motors, the devices are completely motionless. Instead, the Senseg system stimulates your fingers or hand with an electrical field to simulate the feeling of friction or texture.
Check out the video:
Because it uses no motors you can’t hear it and it doesn’t run down the battery. A small module – about as big as two sugar cubes – controls the sensation by connecting to a thin film that can be placed on any device. The film can even go around curves.
I say it’s pretty cool and I want one 🙂
