Abstract
A touch pad includes a flat portion and a convex type three-dimensional portion having a hemispherical shape. An outer circumferential surface of the three-dimensional portion constitutes a spherical operation area. A second recognition unit of the touch-pad controller recognizes a gesture operation of at least two fingers to be the same gesture operation as a pinch-in operation in a planar operation area, in a case where movement trajectories of the at least two fingers in the spherical operation area are arc-shaped movement trajectories which are bulged outwardly in a case where the spherical operation area is viewed in a plan view.
