Abstract

The invention discloses a capacitive sensing-based display screen gesture control circuit and method. The circuit comprises a display screen and sensors arranged around the display; the sensors are arranged in a strip shape; a shielding layer is arranged at the periphery of each sensor; multiple sensors output sensing signals to a detection circuit; the grounded end of the display screen is disconnected with the ground; and the grounded end of the display screen, the sensors and the shielding layers are all connected to a shock signal source. The method comprises the steps of detecting the signals output by the sensors through the detection circuit, and determining the sensors which work currently; loading voltage signals of shock to the sensors which do not work, thereby enabling the voltage signals loaded to the sensors which do not work and the sensors which work to keep synchronous shock; and detecting the signals output by the sensors which work currently through the detection circuit, and according to the changes of the signals output by the sensors which work currently, determining gestures. The changes of the user gestures can be accurately detected; and the production costis relatively low.

Description

technical field [0001] The invention relates to the field of gesture recognition, in particular to a display gesture control circuit based on capacitive sensing and a control method realized by using the circuit. Background technique [0002] Today's electronic devices are becoming more and more intelligent. As people's requirements for electronic devices are getting higher and higher, the gesture recognition function of electronic devices is becoming more and more important. Most existing electronic devices recognize gestures by taking pictures of the user's gestures with a camera, and then recognizing the images to identify the changing process of the user's hand movements based on the images, thereby recognizing the user's gestures. [0003] However, the recognition of user gestures through images and videos captured by the camera device puts forward high requirements on the image processing and image recognition capabilities of electronic equipment, and when electronic e...
