Abstract

The invention relates to a touch screen pressure sensing method and device, equipment and a storage medium. The method comprises the following steps: acquiring capacitance signal data of the touch screen based on a first touch screen response parameter, and calculating to obtain an initial feature vector; establishing a pressure mapping model according to the initial feature vector, and generating pressure distribution data; performing feature extraction and fuzzy quantization to obtain a fusion feature vector; inputting the fusion feature vector into a Gaussian mixture model, and calculating to obtain a dynamic pressure threshold parameter; carrying out change rate, acceleration and jitter degree calculation on the dynamic pressure threshold parameter to obtain a time domain feature sequence; and performing comprehensive operation on the time domain feature sequence, the pressure value and the contact area to obtain a pressure influence factor, adjusting the first touch screen response parameter according to the pressure influence factor, and outputting a second touch screen response parameter. According to the method and the device, the continuity and the stability of pressure detection are improved, and finally more accurate and smoother touch experience is realized.
