Touch-operating input device, display system, and touch-operation assisting method for touch-operating input device

摘要

A touch-operation guide shape is formed on an input pad for inputting a touch operation by variably deforming the surface of the input pad, forming grooves or the like to enable a user to recognize the operation position on the input pad through finger touch. In addition, an image representing the touch-operation guide shape is displayed on a menu frame of a display together with selection items, whereby the corresponding position on the input pad can be recognized on the screen of the display.
