<p>[PLOBLEM] Even when data with a hierarchical data structure is displayed, it can be identified which hierarchy's data a manipulation instruction by a touch operation performed on a touch panel directs to, and thereby a predetermined function can be executed. [SOLVING MEANS] A portable terminal device comprising a touch panel on a display screen is provided with a press operation detection unit for detecting a press operation performed on a predetermined region of the display screen, a sweep operation detecting unit for detecting a sweep operation performed on another region of the display screen, and a terminal data processing unit for identifying the hierarchy of data to be manipulated on the basis of the presence or absence of the press operation detected by the press operation detecting unit and executing processing for the data of the identified hierarchy on the basis of the contents of the sweep operation detected by the sweep operation detecting unit.</p> |
