A display device (1) calculates an operation amount of an operation made by a user on the basis of a detected instruction location (step S17). The display device (1) displays on a display screen (31) a configuration image which is in accordance with the operation amount calculated in step S17. Next, in a case where it is determined that the instruction location can no longer be detected (step S19: YES), the display device (1) determines whether the calculated operation amount is no more than a threshold value (step S20). Subsequently, in a case where it has been determined that the calculated operation amount exceeds the threshold value (step S20: NO), the display device (1) executes an action for acquiring a new e-mail (step S21). |
