Detection means of the display device detects a position designated in the space facing the display surface. Specification means of the display device, on the basis of the position detected by the detection means and a position where the virtual keyboard is stereoscopically viewed, specifies a key designated based on the detected position among keys of the virtual keyboard and an overlapping state between the key and the position. Display control means of the display device controls modes for displaying the keys respectively according to the state specified by the specification means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
