PROBLEM TO BE SOLVED: To provide an input device configured to detect an input operation even when a distance to an object to be touched by a user during the input operation is unknown.SOLUTION: An input device includes: a finger area detection unit 11 which detects a fingertip position on an image obtained by a first imaging unit; a fingertip position calculation unit 12 which determines a corresponding point corresponding to a fingertip position on an image captured by a second imaging unit, and calculates a position of a fingertip in a real space, on the basis of the fingertip position and the corresponding point; a touch operation determination unit 14 which determines whether a feature quantity representing a finger motion calculated based on each of fingertip positions in the real space calculated in a predetermined period may satisfy a condition of a finger touching an object; and a confirmation operation determination unit 17 which causes a projection device to project a predetermined mark when the feature quantity satisfies the condition, and an input operation is determined when the fingertip position in the real space is included in a predetermined area corresponding to a projection position of the mark, in a predetermined period after projection.SELECTED DRAWING: Figure 9 |
