Portable communication terminals equipped with two touch panels are known. In such a portable communication terminal, there are cases where the two touch panels need to serve as a single touch panel. In such cases, however, since each of the two touch panels is independent hardware and they are controlled separately, there has been a problem that it is difficult to move an object such as an icon displayed on one touch panel to the other. Generally, to drag an object displayed on a touch panel, a user first touches the object on the touch panel with a finger. The object moves as the contact point touched by the user's finger moves, and stops when the contact breaks as the user releases the finger. Hence, even when the user wishes to move an object from one touch panel to the other, the object stops at the position on the former touch panel where the contact breaks.
Patent Literature 1, for example, discloses a method as one approach to this problem. According to this method, a plurality of touch panels are managed as a single touch panel by using an integrated coordinate system. To move an object displayed on a first touch panel to a second touch panel, the user first touches the object displayed on the first touch panel with one hand, and while doing so, touches the second touch panel with the other hand, and then releases the hand from the first touch panel. In addition, Patent Literature 2, for example, discloses a portable communication terminal that reduces the load on a user of moving an object between two touch panels.
