PROBLEM TO BE SOLVED: To notify a user of a fact that an operation is accepted, before a motion according to the user's operation is executed.SOLUTION: A display device 1 calculates a control input that a user has performed, on the basis of a detected indicated position (step S17). The display device 1 causes a display surface 31 to display a configuration image according to the control input calculated in the step S17 (step S18). When determining that the indicated position is no longer detected (step S19: YES), the display device 1 determines whether or not the calculated control input is less than a threshold (step S20). When determining that the calculated control input exceeds the threshold (step S20: NO), the display device 1 executes an operation of obtaining a newly arrived e-mail (step S21). |
