Embodiment Construction

[0020] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0021] Such as Figure 1-6 As shown, the gesture recognition device based on FDC2214 of the present invention uses the C8051F020 main control unit 7 as the control core, the FDC2214 capacitive sensor chip 3 as the data acquisition unit, and the TFT liquid crystal display 1 as the display module. The sense plane 4 serves as a sense panel. The C8051F020 main control unit 7 is used as the MCU control core, and it is equipped with an LED digital tube 2 for displaying the sensing value, an LED status indicator 5 for status indication, and a key matrix 6 for setting different detection modes. Equipped with a TFT liquid crystal display driven by an ILI9341 driver to display status information and respond differen...

Abstract

The invention relates to the technical field of gesture recognition, and discloses an FDC2214-based gesture recognition device, which is a capacitive gesture recognition system formed by taking a C8051F020 main control unit as a control core, two FDC2214 capacitive sensing chips as data acquisition units, a TFT (Thin Film Transistor) liquid crystal display screen as a display module and six capacitive sensing planes as sensing panels. The system detects and outputs to the single-chip microcomputer through the capacitance sensing plane and the FDC2214, the frequency is converted into the frequency through a specific formula, and finally the action is analyzed and judged according to the difference value between the frequency and the initial frequency. The whole system has the functions of learning and manual calibration, can accurately and quickly judge the action within a certain range, and can realize the function of controlling the LED small lamp and the LCD screen by gestures through the control of the single chip microcomputer.

Description

technical field [0001] The present invention relates to the technical field of gesture recognition, in particular to a gesture recognition device based on FDC2214. Background technique [0002] The importance of Human Computer Interaction (HCI) in people's work and life is self-evident. Realizing the natural communication between human and working system is the basic goal of human-computer interaction, and gesture is one of the most basic characteristics of human beings, and it is one of the easiest and most convenient control methods for human beings. A more natural, creative and intuitive interactive means of communicating with computers. The application of gesture recognition systems in daily life will become more and more extensive, especially with the continuous development of the Internet of Things era, the market application prospects of gesture recognition systems will surely become wider and wider. [0003] Due to the complexity and meaning of gestures, it not onl...
