yes Sony is using new "optical" infrared touch screen tech. infrared beams are projected in a layer above the display towards detectors on the opposite sides. the "touch" is detected by the fingers interference/ blocking the beam. basically a much smaller version of the beams that ring a chime in shops to let employees know when someone has come in the door.
