Abstract: A detection device includes: a sensor region having a detection region; and a detector disposed on a back surface of a front plate that is a nonconductor. The detector is configured to detect an object to be detected on or above a surface of the front plate opposite to the sensor region and overlapping the detection region based on detection values of electrodes in the detection region. The detector includes: an initial setter configured to set a second distance not smaller than a first distance in a height direction of the front plate and register XY coordinates of an indicator in an XY plane where the object to be detected is detectable; a storage configured to store a parameter generated by the initial setter; and a gesture determination processor configured to determine a gesture corresponding to change in spatial coordinates of the object to be detected based on the parameter.
