PROBLEM TO BE SOLVED: To provide an information input system which dispenses with a signal cable for transmitting information to a computer. SOLUTION: A transceiver 3 provides a transmission electrode 105 with a signal of steady-state intensity. The signal is induced in a human arm as an electric field and is transmitted to a keyboard 5, which grounds a key in a pattern according to the key, when the key 51 is depressed. Therefore, a signal induced in the transceiver 3 as an electric field via a reception electrode 111 generates a signal of intensity, decreased in a pattern according to the key, when the key 51 is depressed. Consequently, the transceiver 3 generates digital data according to a signal received with the reception electrode 111 and provides data to a wearable computer 1, which provides display according to the data on a monitor 1B.
