1. A detecting device comprising:
a sensor unit having a plurality of electrodes; and
a detector configured to detect a gesture corresponding to movement of an object in a space on the sensor unit, wherein
the detector detects that a predetermined gesture is made when a distance between the sensor unit and the object is equal to or smaller than a first distance,
the detector detects that the predetermined gesture is made when the distance between the sensor unit and the object is equal to or smaller than a second distance larger than the first distance and is larger than the first distance and when a movement speed of the object to be detected in the space is equal to or smaller than a predetermined value,
the detector comprises:
a coordinate calculator configured to calculate a spatial coordinate of the object in the space based on the detected value of each of the electrodes; and
a gesture determination processor configured to determine whether the predetermined gesture is made based on the spatial coordinate,
the coordinate calculator calculates:
first data indicating coordinate data in an X-direction;
second data indicating coordinate data in a Y-direction orthogonal to the X-direction; and
third data indicating coordinate data in a Z-direction orthogonal to the XY-plane,
the third data is larger as the distance between the sensor unit and the object is smaller,
the gesture determination processor determines that the predetermined gesture is made when the third data is equal to or larger than a first threshold corresponding to the first distance, and
the gesture determination processor determines that the predetermined gesture is made when the third data is smaller than the first threshold and equal to or larger than a second threshold corresponding to the second distance, and when a movement amount per unit time in the XY-plane is equal to or smaller than a second threshold and when a magnitude of a movement amount per unit time in the Z-direction is equal to or smaller than a third threshold.
