Abstract
A data input device uses a palatal plate formed of resin that includes multiple sensors. The sensors detect whether the palatal plate is in contact with the tongue or not. An output (on-off) of the sensor is supplied to an IC. The data corresponding to the output of the sensor, i.e. a form of the tongue-palate contact, are transmitted from the IC through an antenna to an external equipment.
