Abstract:
1. A method for inputting information executed by the information input device comprising: an applying element being a coil and having a ring shape so that a finger of a user is inserted into the applying element; a receiving element being a coil and having a ring shape so that a finger of a user is inserted into the receiving element and disposed adjacent to the applying element in an extending direction of a center line of the applying element; a signal generating element generating and transmitting a waveform signal to the applying element so that the applying element induces an induction current corresponding to a measurement signal on the finger inserted into the applying element; and a signal extracting element extracting a signal relating to a bending and stretching posture of the finger from a signal relating to an electro motive force as a reception signal, which is output from the receiving element based on the induction current, the method comprising: a standard storing step of extracting a first signal relating to the bending and stretching posture of the finger from the reception signal with the signal extracting element when the finger inserted into the applying element and the reception element takes a standard posture, and storing the first signal relating to the bending and stretching posture of the finger as a standard signal; an extracting step of extracting a second signal relating to the bending and stretching posture of the finger from the reception signal when the finger takes a certain bending and stretching posture; and an output calculation step of subtracting the second signal relating to the bending and stretching posture of the finger extracted at the extracting step from the first signal relating to the bending and stretching posture of the finger stored at the standard storing step, and outputting a subtracted result.
