<p>An operation apparatus is provided with: a touch operation unit equipped with an operation face; and a control device that responds to a selecting operation applied to one of selection items displayed on a display apparatus that is remotely disposed with respect to the touch operation unit, on the basis of the two-dimensional coordinates of a contact point of a finger within the operation face. The control device operates in the absolute-coordinate mode, wherein the coordinate system of the display apparatus corresponds in an absolute state to the coordinate system of the operation face of the touch operation unit, when none of the selection items is selected, and operates in the relative-coordinate mode, wherein the coordinate system of the display apparatus corresponds in a relative state to the coordinate system of the operation face of the touch operation unit, when either of the selection items is selected.</p> |
