1. An input device, comprising:

  • a detection unit for detecting one or more radially directed input forms of vertical pressing, horizontal pressing, tilting pressing, contact, and contact movement;

    an input tool for enabling two or more radially directed input forms corresponding to each of the one or more radially directed input forms detectable by the detection unit to be performed, one or more portions of the input tool selectively contacting with the detection unit; and

    a controller for generating a plurality of radial direction indication locations corresponding to the two or more radially directed input forms performed by the input tool, extracting data assigned to the radial direction indication locations corresponding to the two or more radially directed input forms from a memory unit, and inputting the extracted data when the one or more radially directed input forms are detected by the detection unit,the controller generates one or more of a plurality of first direction indication locations M, and one or more of a plurality of second direction indication locations P on a basis of a portion of the input tool contacting with the detection unit, detects first directional input performed in such a way that the input tool is moved to any one of the first direction indication locations M while contacting with the detection unit, in response to a detection signal output from the detection unit, detects second directional input P, which is performed in such a way that another portion of the input tool contacts with any one of the second direction indication locations P on the detection unit, in response to a detection signal output from the detection unit, extracts data assigned to the first direction indication location M or the second direction indication location P from the controller, and inputs the extracted data,wherein the first direction indication location M and the second direction indication location P are radially arranged from a reference location S,the reference location S is disposed at the center of the first direction indication locations M and the second direction indication locations P.
