Claim 0:
1. A detecting device comprising:
a sensor unit having a detection region in which a plurality of electrodes are arrayed; and
a detector configured to detect a gesture corresponding to movement of an object to be detected in a space on the detection region based on a detected value of each of the electrodes, wherein
the detector detects that a predetermined determination gesture is made when a distance between the sensor unit and the object to be detected is equal to or smaller than a first distance,
the detector detects that the determination gesture is made when the distance between the sensor unit and the object to be detected 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 on the detection region is equal to or smaller than a predetermined value,
the detector comprises:
a coordinate calculator configured to calculate a spatial coordinate of the object to be detected in the space on the detection region based on the detected value of each of the electrodes; and
a gesture determination processor configured to determine whether the determination 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 to be detected is smaller,
the gesture determination processor determines that the determination gesture is made when the third data is equal to or larger than a first determination operation determination threshold corresponding to the first distance, and
the gesture determination processor determines that the determination gesture is made when the third data is smaller than the first determination operation determination threshold and equal to or larger than a second determination operation determination 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 movement amount threshold and when a magnitude of a movement amount per unit time in the Z-direction is equal to or smaller than a first movement amount threshold.
