Abstract
An input operation system for use in a vehicle has a protruding marking on a surface of a touch panel, and displays a composite image generated by superposing an outline of user's finger on a switch operation screen. The composite image of the switch operation screen is backed by an image of the protruding marking on the surface of the touch panel, and the user's finger receives a tactile feedback from the protruding marking on the surface of the touch panel to cause sensations of an intuitive positioning in the switch operation screen for controlling a menu item that is displayed on a display unit for an input operation of vehicular devices.
