Position information input device and position information input method

摘要

A position information input device is provided with input positions assumed to be some positions of the surface of a conductive object, one or more signal receiving electrodes provided in other positions on the conductive object correspondingly thereto, for receiving a positioning signal inputted to each input position, and a signal input transfer module for transferring the same positioning signal specific to the input position. A signal generation/output module is provided together with the signal input transfer module, for generating the positioning signal in which a plurality of signals having different frequencies are defined as one group. The position information input device calculates path resistance values between the input position and the signal receiving electrodes from the respective values of the positioning signals received by the signal receiving electrodes and specifies the input position from the differences thereof.

1. A position information input device being a terminal, comprising:
an input unit formed with a single or a plurality of signal transmitting units for dispatching an electric signal in response to one part of a body that holds the terminal directly touching another part of the body for making an input and a plurality of signal receiving units for detecting the electric signal and outputting detection data; a dispatch/generation module which generates the electric signal for the signal transmitting unit(s), outputs the generated signal as dispatch data, and outputs output chronic timing thereof and a state of the generated signal as generation data; and an input information specifying module which specifies a contact position by referring to the detection data, the generation data, and accumulation data in a database set in advance, and outputs the position as input information specification data, wherein the input information specifying module calculates electric impedance properties from electric current values and voltage values as the detection data based on timings showing each frequency as the generation data, calculates an electric impedance as a target based on physical electric properties of at least one of bones, muscles, tendons, joints, skin, and blood of the body by referring to the accumulation data of the database set in advance, and specifies the contact position from the electric impedance.
