1. An input device, in which a detection section is contacted by a portion of an object, and when a trailing operation (an operation of sliding a portion other than a contact portion of the object in the vicinity of the contact portion of the object) is performed in the vicinity of the contact portion of the object, the trailing operation is specified and a display corresponding to the trailing operation is presented, the device comprising: a detection section which is contacted by a portion of the object, and when trailing is performed in the vicinity of a contact portion of the object, detects a force transmitted via the object and outputs the force as detection data; a timer management control unit which generates a timing for recording the detection data at a time interval, and outputs the timing as timing data; and an input information specifying unit which creates time-series data of the detection data based on the detection data and the timing data, compares the time-series data with stored data in a database which has been set beforehand, specifies an input operation, and outputs the input operation as input information specifying data.
