PROBLEM TO BE SOLVED: To obtain an information input device allowing various input choices.SOLUTION: One of a plurality of screens showing input options is displayed on a display panel 12. A three-dimensional position detection device 30 detects three-dimensional coordinate values of an operation body. A cube area determination unit 31 determines, on the assumption that a three-dimensional space on the front side of the display panel 12 is divided into a plurality of cubic virtual spaces, which of the cubic virtual spaces the three-dimensional coordinate values of the operation body are included in. The screens of input options are assigned to the virtual spaces respectively. When a virtual space is determined by the cube area determination unit 31, the screen of the input option corresponding to the virtual space is displayed on the display panel 12. |
