  • Publication number: 20170017322
    Abstract: An input device according to the present invention includes a touch panel (1), display means (2) provided to be superimposed on the touch panel (1), measurement means (11) that is able to measure a measurement value corresponding to a situation whether a glove is worn and a thickness of the glove, and sensitivity setting means for setting sensitivity of the touch panel (1) according to the measurement value measured by the measurement means (11). The measurement value may be a value corresponding to a range in which an electrostatic capacitance of the touch panel (1) has changed, for example, and the sensitivity setting means (12) increases the sensitivity of the touch panel (1) as this value increases. It is therefore possible to provide an input device that is able to improve operability regardless of whether the glove is worn or even when a different type of glove is worn.
