摘要 |
Disclosed is an information input device including a touch panel in which a display screen for displaying operations information is integrated with a sensor unit and to which the operations information is input when the display screen is touched with a predetermined unit, the sensor unit having plural sensors, which are capable of measuring a capacitance at a front surface of the display screen, arranged in a staggered manner such that three of the plural sensors adjacent to each other are arranged at positions corresponding to apices of a regular triangle; and a position determination unit that determines a position touched with the predetermined unit on the display screen in accordance with levels of the capacitances detected with the three adjacent sensors in a region of the regular triangle formed by the three adjacent sensors among the plural sensors constituting the sensor unit.
