1. An electronic device comprising: a display unit configured to display a plurality of input objects; a contact detection unit configured to detect a contact of a contact object on the display unit, respective one of the input objects having a predetermined standard of force required to detect a press on the contact detection unit for activating an application associated with the respective one of the input objects; a press detection unit configured to detect a press on the contact detection unit by a pressing operation of the contact object on the display unit; and a control unit configured to detect that a contact of the contact object on the display unit at a position corresponding to one of the input objects to select the one of the input objects displayed on the display unit is detected by the contact detection unit and that data based on the press on the contact detection unit by the pressing operation of the contact object on the display unit at the position corresponding to the one of the input objects detected by the press detection unit satisfies the predetermined standard of the one of the input objects, and then to activate the application associated with the one of input objects, the control unit being configured to differentiate the predetermined standard of the one of the input objects from the predetermined standard of an input object adjacent to the one of the input objects based on a frequency of use of the application associated with the one of the input objects.
