INPUT DEVICE

An input device capable of enhancing operability is provided, including: a display control unit that displays an operation screen on a display surface, and a first detection unit and a second detection unit 8 that detect respective positions of an object in a first sensing layer and a second sensing layer in air formed side by side in a direction substantially perpendicular to the display surface. When the object passes through the first sensing layer in a direction approaching the display surface, the display control unit determines a first partial operation screen including a position on the operation screen corresponding to a position of the object in the first sensing layer based on respective detection results of the first detection unit and the second detection unit, and enlarges and displays the determined first partial operation screen on the display surface.
