Abstract: An input device includes a display that displays buttons visible through an operation surface of a top panel, a detector that detects a center position of a finger facing the operation surface, and a distance from the operation surface to the finger, and a controller that controls the display based on a detector output and determines an input with respect to a button. The controller displays a cursor image on the display at a finger opposing position based on the finger center position, varies a cursor size according to the above described distance, determines a selected button based on the finger center position, and offsets a cursor center position from the finger center position, and surrounds the selected button with the cursor, in a case where the selected button protrudes from the cursor when the cursor center position is aligned to match the finger center position.

Abstract: A contactless input device includes a plurality of sensor electrodes and a determination unit. The plurality of sensor electrodes are configured to, when a hand performs an operational input over an operating surface of an operating part in a contactless manner, detect individual capacitances correlated to proximity of the hand to the operating surface. The determination unit is configured to calculate sharpnesses of the hand at a plurality of different locations in plan view based on the respective capacitances detected by the plurality of sensor electrodes and determine a location of the operational input based on the sharpnesses.
