In order to achieve accurate gesture recognition, the circuit schemes of each unit are compared, demonstrated and determined. The system uses the TIVAC series of Texas Instruments as the processing core, obtains the corresponding gesture information through the FDC2214 capacitive sensor, the copper-clad sensing board distributed in the shape of the palm, and other external circuits, and uses 5mm thick glass as the test panel. The bottom wooden board is wrapped with aluminum foil for grounding and shielding. The data of capacitance detection is processed through the variance comparison algorithm, and finally the gesture result is obtained and output through the OLED screen.
