Date posted: 13/03/2009 A prototyped capacitive touch panel was demonstrated by Mitsubishi Electric Corp at the Interaction 2009 in Tokyo, Japan. The 3D touch panel can detect not only x- and y- coordinates but also its z- coordinates by detecting the distance between a finger and panel. Screen size is approximately 5.7 inches with a resolution of 640 x 480 pixels. The 3D touch panel functions by switching between two detection methods and would be determined by the position of the finger. When a finger approaches the panel, it's defined as being in "proximity state" After the finger is in contact with the panel it's in "contact state". In "proximity state", priority is given to the screen's sensitivity and in "contact state", resolution has priority. The panel can detect a capacitance change of approximately 0.3pF in the proximity state and about 8 to 19pF in the contact state, according to a spokesperson for Mitsubishi Electric Corp.
