<P>PROBLEM TO BE SOLVED: To provide a display device and the like capable of performing intuitive selection by a three-dimentional operation on information having a hierarchal structure. <P>SOLUTION: A display device includes a display unit 14 that can display a 3D image, a 3D image generating unit 20c that includes information for each hierarchy among information having a hierarchal structure and generates a plurality of images displayed three-dimensionally at a position corresponding to the hierarchy via the display unit 14, a finger position sensor 16 that three-dimensionally detects coordinates of a representative point of an object existing in a three-dimensional space including a display region of the plurality of images, and an input signal receiving unit 20d that receives input corresponding to information included in each of the plurality of images based on the coordinates of the representative point detected by the finger position sensor 16. <P>COPYRIGHT: (C)2012,JPO&INPIT |
