Abstract

An input device includes an input section having a detection section which detects a force transmitted via a human body when a trailing operation is performed on a part of the body contacting the input device, and outputs the force as detection data “a”; a timer management control unit which generates a timing for converting the detection data “a” into time-series data and outputs the timing as timing data “c”; an input information specifying unit which converts the detection data “a” into time-series data based on the timing data “c”, compares the time-series data with stored data “b” in a database which has been set beforehand, to thereby specify an input operation and output the input operation as input information specifying data “d”; and an information presenting unit which, upon receiving the input information specifying data “d”, displays a function assigned to the input operation.
