Design and Implementation of Gesture Operation for Handheld Instruments Based on Touch Screen
With the increasing use of touch screens,the new generation of handheld spectrum analyzer has abandoned physical buttons and knobs and fully adopted touch screens as the main way of human-computer interaction.In the new human-computer interaction mode,in order to highlight the advantages of touch screens and improve the human-computer interaction experience,a solution for touch screen gesture operation in the spectrogram of handheld spectrum analyzer is designed and implemented through the analysis of commonly used setting parameters in the spectrogram and the recognition analysis of different touch gesture actions.This solution distinguishes different gesture actions,responds in real-time,and calls corresponding interfaces to modify the corresponding spectrum parameters.Compared to using traditional instrument panel buttons and knobs to set parameters,gesture operation is more convenient,greatly improving the user experience.
