Lucid Touch
Microsoft and Mitsubishi are working together to create a new way to use touch screens called “Lucid Touch”. This method uses a touch screen on both sides of a device allowing you to use your fingers on the back screen, and your thumbs on the front screen. While your fingers are near the back screen theya re shown on the front screen so you can see where you are touching.
