Projective capacitive sensing is usually applied to mobile touch screens. To the contrary, most large touch screens such as MS Surface and Perceptive Pixel use camera-based techniques. One reported exception is Sony SmartSkin that uses projective capacitive sensing.
Today, I found another example of large touch screens using projective capacitive technology.
The big difference between those two is the sensor material. In the projective capacitive sensing, a mesh of electrodes acts as a touch sensor. SmartSkin uses copper electrode, while the one shown above utilizes ViP Interactive Foil.
At this time, only thing I know is that it is flexible, transparent and provided by Viual Planet.
I should check it out later.
