Abstract: A method and apparatus for tracking input positions via Electric Field Communication (EFC) are provided. The apparatus includes a plurality of receiving electrodes for EFC and a receiver unit. The receiving electrodes detect strengths of input electric fields. The receiver unit compares the strengths of the input electric fields with each other and generates position information regarding the input electric fields.
