Input apparatus for vehicle
An input apparatus for vehicle includes a display origin displaying unit, a finger detector, an axial position detector, and a display content selector. The axial position detector causes positions of respective fingers of a driver, detected by the finger detector provided on a steering wheel rim in a circumferential direction thereof, to correspond to axial positions in respective first and second directions of axial directions set to a display. The first and second axial directions are respectively set corresponding to first and second directions of directions, starting from a second origin, in the circumferential direction. The second origin is set to the steering wheel rim and corresponds to a first origin displayed on the display. The display content selector selects a content displayed on the display, on the basis of an intersection of the axial positions in the respective axial directions brought into the correspondence by the axial position detector.
