And determining gesture information by capturing the change condition of the electric field, so as to control the controlled equipment according to the gesture information.
First, a gesture control apparatus provided in an embodiment of the present invention is described below.

As shown in fig. 1, the apparatus includes:
a signal receiving element 10 on the top layer, a ground element 30 on the bottom layer, and a signal transmitting element 20 disposed in the middle layer between the top and bottom layers. Insulating material 40 is disposed between the top layer and the middle layer and between the middle layer and the bottom layer.
The signal transmitting assembly 20 includes an emitter electrode positioned below the signal receiving assembly 10.
Fig. 2 is a schematic structural diagram of a signal receiving component according to an embodiment of the present application. Fig. 3 is a schematic structural diagram of a signal receiving assembly according to another embodiment of the present application. As shown in fig. 2 and 3, the signal receiving module 10 includes a metal grid 11, a first receiving electrode 13 connected to the metal grid 11, and a second receiving electrode 12 disposed around the metal grid 11.
As shown in fig. 3, the first receiving electrode 13 is located on the top layer together with the metal grid 11 and below the metal grid 11.
Here, the emitter may be disposed only under the metal grid 11 and the second receiver 12, or may extend over the entire intermediate layer.
Alternatively, the metal grid 11 may be made of copper, or may be made of other metal materials.
In this embodiment, utilize electric field induction principle, upwards launch the electric signal through signal transmission subassembly and form the electric field, because electric field transmission changes when the staff is close to, the gesture is discerned to the electric field change request that senses based on the signal reception subassembly. Therefore, the gesture recognition only needs simple signal comparison calculation, consumes less calculation resources and has higher recognition speed. Moreover, the gesture recognition is only based on the change of the electric field and is not influenced by light rays, so that the application universality and the accuracy of the gesture recognition are improved. In addition, the hardware cost required by the gesture recognition device is reduced.
On the other hand, a metal grid is arranged in the middle of the top layer of the gesture control device, and an electric signal sent by an emitting electrode in the middle layer penetrates out through the hollow-out part of the metal grid to form an electrostatic field. When the hand approaches the metal grid area, the static electric field is disturbed, and the distance change between the hand and the metal grid in the vertical direction is reflected by the disturbance of the electric field.

Through the disturbance condition of the electric field, the hand approaching or departing from the metal grid can be recognized, and the gesture control device can recognize the gesture change in the direction perpendicular to the metal grid, namely the descending or ascending action of the hand can be recognized. Therefore, the device of the embodiment can recognize gesture actions in the horizontal direction and also can recognize gesture actions in the vertical direction, so that the accuracy of gesture recognition is improved, and a user can perform more control on the controlled device through the gesture actions due to the fact that more types of gesture actions can be recognized.
